Taunton manufacturing history

In a sense this is a story about the most simple manufacturing process, the turning of apples into cider. Yet it draws in strands of the commercial world which are common to a great many manufacturing businesses.

Apples grow well in a number of areas of the country and from early times local people have found the benefit of extracting their juice and allowing it to ferment. Being a simple industry, anyone can do it - to a degree. It is also a local industry with lovers of cider fiercely loyal to the taste of the apples they know. The same is true of breweries, except that cider can be made on a very small scale.

R.W. Holder traces the story of Taunton cider back to the Rectors of Heathfield in the early nineteenth century. Rural areas were suffering in what became known as the hungry forties, but land owners generally escaped and it was the poor who suffered. A Rector was in sense a land owner since he lived off the rents of the Glebe and the proceeds of the Tithe. The Rector of Heathfield lived in cider country and was in the financial position to exploit his product and he did so by supplying the rich and famous.

As was the case in many places it was the railway that unleashed the business of Taunton which was not served by decent roads nor by easily navigable rivers. Railways, the GWR, proved ideal to transport hogsheads of cider to London and all parts of the country. The railways also expanded the market for local food producers and Holder tells the story of Mrs Langdon who built a business supplying eggs, chicken and rabbit to the London market.

The Taunton cider business grew by building relationships with brewers and their tied houses. Slowly the number of brewers increased each having a shareholding in Taunton Cider. Mrs Langdon's business, now run by her sons, recognised the role of logistics in their business and realised that they were at heart hauliers and could compete well with the stuck-in-the-mud railways. Langdons grew and Taunton grew and eventually the former was transporting the cider of the latter in large quantities.

The cider market was tough. H.P. Bulmer of Hereford was in the lead, with also Whiteways of Whimple in Devon and Gaymers of Attleborough in Norfolk close behind. The drinks market was also changing. Britvic of Chelmsford and Showerings of Shepton Mallet were transforming the image of the drink. With this background Taunton Cider was sold first to management, then floated on the London Stock Exchange until it became part of Matthew Clark plc and in turn C&C (Cantrell and Cochrane) founded in Belfast but then based in Dublin. C&C already owned Gaymers and Matthew Clark the Irish firm of Magners. The original Taunton Cider moved production elsewhere, but Heritage Cider has taken its place in the town.

Cheltenham & Gloucester manufacturing history

 In the fifteenth century Gloucester was another centre for the wool and cloth industry. Work with iron was if anything more important with smelting from the Forest of Dean and foundries in the city. There is evidence then of further metal trades: cutlers, bladesmiths, coopers, farriers and pinners. In the thirteenth century, more towns had come to be known for their product: Lincoln for cloth (dyed green or scarlet), Grimsby for fish, Corfe for marble and Gloucester for iron.

In the sixteenth century the wool trade declined, but the city was appointed a port which went some way to increase trade, although Bristol continued to dominate. Cheltenham made its name as a Spa Town. The eighteenth century also saw Gloucester run more by the gentry, but the coming of the canals and railways, as elsewhere, brought manufacturing industry to the city.

This was in the shape of one remarkable company, the Gloucester Carriage and Wagon Company formed in 1860. Its traditional business had been fine carriages for the gentry, but the need to transport coal brought in the coal wagon for use on railways of which the company manufactured a great many. The design of wagons was developed and a greater use was made of iron and steel. Passenger carriages were produced mainly for overseas customers. The London Underground became a major customers with carriages produced for a number of lines. The company worked with English Electric on rolling stock for electrified railways. The company ceased manufacture in 1986.

In Cheltenham in 1888, Herbert Henry Martyn founded a company of wood, stone and plaster carvers, metal and glass workers. The company gained a national reputation for the excellence of their work. During the First World War, Hugh Burroughs of the Aircraft Manufacturing Company of Hendon (Airco) was looking for subcontractors to make wooden DH2 Scout aircraft. He was advised to visit Alfred Martyn who had taken over from his father. Burroughs was impressed and gave the order. Clearly a good relationship developed because Burroughs and Martyn set up a new company, the Gloucestershire Aircraft Company, owned by their respective companies.

The Gloucestershire Aircraft Company or Gloster Aircraft as it became, began by building large numbers of Bristol Fighters and Nieuport Nighthawks and, after the war ended, set about using large quantities of surplus Nighthawk parts to produce a series of planes derived from the Nighthawk which they named the Sparrowhawk and many of which were bought by the Japanese Navy. The Schneider Trophy beckoned and the company made a number of racing seaplanes. The interwar years were spent in experimentation as designs were tried out moving from wood to metal construction. This cost dear and Gloster became part of the much larger Hawker Siddeley which drew the company into the Hawker fold. A large number of aircraft were built including the Gladiator, the last bi-plane fighter.

Gloster had the distinction of being the first aircraft manufacturer in the UK or US to design, build and fly an aircraft fitted with a jet engine. I write about the development of the jet in How Britain Shaped the Manufacturing World. The company went on to produce the highly successful Meteor.

Gloucester was home to Rotol, formed by Bristol aircraft and Rolls-Royce to manufacture propellers. Dowty Aviation with which Rotol later merged was based in Cheltenham specialising in undercarriages. The Dowty Heritage site has much more excellent detail. George Dowty, the founder of the company in 1930, had been a draughtsman at Gloster Aircraft designing internally sprung aircraft wheels in his spare time. Joe Bowstead and John Dexter joined him on their first contract for struts for the de Havilland autogyro. Soon they went full time and began building a company that would provide vital parts for the growing aircraft industry. George Dowty was a great believer in subcontracting, both to hold steady the company's employee numbers and to drawn on more specialist skills. I write more of the post war British aircraft industry in Vehicles to Vaccines.

Unilever set up their Walls ice cream factory in Gloucester. In nearby Coleford, Lucazade and Ribena are produced. Ribena was produce by H.C Carter and was bought by Beecham and joined by Lucazade. They were sold by GSK to Suntori in 2013.

Bristol manufacturing history

 In 1843 Isambard Kingdom Brunel built a revolutionary ship in Bristol’s western dock. It was iron hulled and had both steam engine and sails. The principal innovation was the screw propeller replacing the paddles used up to that point. The image is of a replica of the original propeller on the conserved SS Great Britain at its home in the dry dock in Bristol.

The ship made the trip to Australia some thirty times and ended its service coaling the British fleet in the First World War. It offered luxury

Alongside hardship

Steerage class

Bristol’s history is maritime and inevitably bound up with slavery as were so many British ports. The maritime link led to the city’s principal businesses WD and HO Wills with cigarettes and JS Fry with chocolate. The city also refined sugar. The presence of these businesses and extensive foreign trade encouraged the development of banking in the city which, until comparatively recently, prided itself on its ability to finance its own business.

Shipbuilding was important, but, like textiles and iron, Bristol didn’t have the advantages of competing northern cities. Nonetheless the city had a major cotton mill for over a century. Before this, like many parts of the country, it was a centre of the woollen cloth trade. It gained a reputation for skilled iron work. The size of the dock limited the size of ships that could be built. The same was less true of non-ferrous metals.

The Mendips had reserves of both lead and zinc. Lead was mined and smelted during the nineteenth century. The arsenic content hardened the metal making it suitable for use as shot. It was a Bristol engineer who invented the process of making shot by dropping it from a tower through a sieve into cold water thus producing perfectly spherical shot.

Zinc had many uses. Added to copper, mined in Cornwall, it made brass largely for Birmingham manufacturers. The smelting of the ore released sulphuric acid used in the production of tin in Swansea just over the Bristol channel. Zinc was also used in galvanising first iron and then steel. John Lysaght set up in Bristol to exploit this process; he added mills in Newport and Wolverhampton and eventually became part of GKN. A fourth use of zinc as an oxide is used in medical products.

Bristol's relationship with zinc came in two major phases. William Champion began exploitation in 1743 and the industry thrived and then declined as Birmingham took more of the processing. The First World War offered a resurgence. Then zinc ore was coming from Australia and was being smelted in Germany before subsequent import into Britain. Clearly the war put a stop to this and Winston Churchill commissioned a major zinc production plant on Avonside, the National Smelting Corporation, which was completed in 1923. In 1928 it became part of the Imperial Smelting Corporation and then faced a long period of decline as the demand fell back to peacetime levels. Imperial Smelting, also in Swansea, became part of RTZ.

WD and HO Wills distinguished themselves from the many other cigarette makers by their technical innovation and marketing. In 1902 they became the largest part of the new Imperial Tobacco. Both Wills and Fry had attracted packaging businesses. ES & A Robinson emerged as a leader and later merged with Dickinson of Hemel Hempstead. Printed packaging materials were needed in ever increasing quantities. The most significant manufacturer became part of Imperial which later dramatically increased production only for it to fall back as cigarette smoking declined in popularity.

The GWR connected Bristol to London in 1841, with the workshops at Swindon. Nevertheless there was room for more, and engineering came to Bristol in the form of locomotive and railway wagon builders. These were followed by trams, out of which the Bristol Aeroplane Company emerged. In the Second World War it employed over 50,000 people and built such iconic aircraft as the Blenheim. Bristol Aero Engines was later bought by Rolls-Royce; their Olympus powered Concorde. The British Aircraft Corporation, into which Bristol Aircraft merged, built their Concorde at nearby Filton. I write of this in Vehicles to Vaccines. BAE Systems still manufacture aircraft at Filton where Airbus UK also carry out design work. At nearby Abbey Wood, BAE Systems manufacture combat vehicles. The Bristol Motor Company was a child of the city. The Douglas Motor Cycle company manufactured many thousands of motor bikes in the First World War. This was bought by Westinghouse Brake and Signal and made brakes and signals but also Vespa scooters.

More recently Bristol attracted service businesses and also inward investment; Hewlett Packard built a factory to the north of the city in the 1980s. The semiconductor manufacturer Inmos (later owned by Thorn EMI) had a design centre in Bristol. Bristol now thrives as a predominantly service economy.

Crawley manufacturing history

 Crawley was a village on the Weald and had played its part in the early Wealden iron industry until the seventeenth century. The Weald supplied iron ore to local and then London based foundries for the production of weapons before both trades gravitated to the coal of the West Midlands. I write more about the Wealden iron industry in a separate blog piece.

In the eighteenth century Crawley's position on the main London to Brighton road brought carriage trade which increased with Brighton's popularity. The arrival of the London to Brighton railway put pay to this, but brought Crawley closer to the ever growing London.

After the Second World War, Crawley was eventually designated a new town and prospered as a result. Manufacturers were attracted but only few larger concerns, the majority being SMEs.

Vent Axia was formed with the invention of the first electrically operated window ventilator in 1936. The company provided ventilation equipment for 10 Downing Street during the Second World War and moved to a factory in Putney in 1946. In 1957 it took a 99 year lease of a factory in Manor Royal, Crawley where it still manufactures after a short period of offshore manufacture in China. Vent Axia was bought by Halls of Dartford and the combined business became part of APV.

APV, founded in Wandsworth in 1910, set up in Crawley in the fifties. Its full name was the Aluminium Plant and Vessel Company and was working with a new way of welding aluminium. It began making heat exchangers and developed into supplying equipment for the dairy, food and chemical industries. In 1987 it merged with Baker-Perkins, but the APV business was bought be Siebe in 1997. At one time it had 1,600 employees.

The subsequent massive growth of Gatwick airport encouraged a good many supporting businesses and housing for a large number of airport employees. The Manor Royal business district has also attracted a good number of businesses, many with international connections.

In recent years Crawley had become the headquarters for Gatwick Diamond a designated economic development area comprising Crawley, Epsom & Ewell, Horsham, Mid Sussex, Reigate & Banstead and Tandridge. It is home to 45,000 businesses and claims better economic performance than similar areas: Thames Valley including Reading, South East Midlands including Milton Keynes and Enterprise M3 including Woking and Greater Medway including Chatham. It highlights Life Sciences and Knowledge Based Industry as key areas.

Reigate and Redhill manufacturing history

 This area of Surrey is rich in sand, chalk, clay and rock all suitable as building materials. Some of the sand is very fine and so ideal for glass making. There is also evidence of some twelve windmills dating from early times. Geared water mills had been introduced by the Romans and some 6,000 are mentioned in the Domesday Book. It was long thought that these were only for grinding grain and a good many were. However, certainly by the early Middle Ages water mills were adapted to other uses including fulling cloth, hammering hot metal and sharpening tools.

The Reigate area had the disadvantage of a lack of constantly running water. I write elsewhere of the use of ponds to regulate water flow; the solution in Reigate was the windmill and a number of the twelve mills mentioned were powered by wind. Fullers earth was also found nearby and so the application of wind mills to fulling was entirely feasible; there was also no shortage of sheep.

The Surrey Iron Railway built in 1805 was planned to go all the way to Portsmouth to facilitate transport during the Napoleonic wars, but in fact ended at Merstham just short of Reigate. Nevertheless it did serve to assist in the transport of Merstham rock and other building materials in great demand as London expanded.

One of the watermills, Salford Mill, was extensively upgraded including the installation of steam power and this was said to have been used by Dr Kellogg for the flaking of wheat until he moved his breakfast cereal business to Manchester

In 1919, the Redland Tile Works began making concrete tiles using the local reserves of sand; local chalk and clay were also available to make the necessary cement. The business was successful, given the demand for building following the war; there was also ample labour in the shape of ex-servicemen.

Carter Wilkinson engineers invented a tile making machine that dramatically speeded up the process and it became a subsidiary of Redland which then exploited the invention through granting licences in many countries. The Redland Engineering business remained in Reigate, but tile making moved to the Moorhouse Tile Works in Kent. In time Redland opened tile works at Syston in Leicestershire and elsewhere across the country. It bought small local brick companies, and in 1984 bought the famous traditional tile manufacturer, Rosemary Roof Tiles. Redland expanded considerably in the seventies and eighties. A revolutionary flat roof system, Icopal invented by David Anderson, had followed the concrete roof tile in 1923 with a factory in Trafford Park in Manchester. Redland was acquired in 1997 by the French Lafarge. The Anglo-Irish company BMI now owns both Redland and Icopal.

A survivor from early times was the British Wax Refining Company of Redhill which purifies and bleaches beeswax. Beecham Research Laboratories were at nearby Brockham Park

The Monotype works at Salfords, near Redhill, was founded in 1899 to manufacture compositing machines for the rapidly expanding printing industry. Monotype Corporation originated in the USA and owner Tolbert Lanston invented a method of mechanical hot metal typeset whereby a typed script could be automatically converted into metal characters. As the twentieth century progressed, the style of type face became more and more important and different families of fonts were devised, for example the well known Times New Roman. Monotype Ltd was very much a partner with its US parent being as involved in developing technology and design. The UK company was floated on the London Stock Exchange with a British board of directors including Harold Macmillan of the publishing house of the same name. Monotype expanded and bought the rival system Linotype which worked with lines of text rather than individual characters.

Reigate, Redhill and the surrounding area are now predominantly residential.

Maidstone manufacturing history

 A market town and the county town of Kent, the 'Garden of England', Maidstone was home to manufacturers exploiting local produce. Kent is known for hops and so breweries flourished. The county is also known for its fruit and so Grants Cherry Brandy but also jam and confectionary makers most notably Sharp's Toffee. Sharps were bought by Trebor which had started out in South London, set up a factory in Chesterfield to escape enemy bombing during the Second World War and became the fourth largest confectionary manufacturer with main competitors Cadbury and Rowntree. Cadbury bought the expanded Trebor in 1989 and the Maidstone factory closed in 2000. The Maidstone factory was known as the Kreemy Works, the largest toffee factory in the world.

It is a town on the Medway and so had a plentiful supply of water for paper making both for specialist uses and newsprint. Hayle Mill made the renowned Bockingford water colour paper.

It is not far from London and so took on a role in support of the metropolis in terms of homes for commuters but also manufacturers to support the London infrastructure. WA Stevens experimented converting a motor car to electric power. In conjunction with London bus company Tilling this developed a drive system whereby a petrol engine powered an electric motor which in turn drove the front wheels of a bus. For a bus driver this held the advantage over a crash gearbox before synchromesh was invented. London bus operator Thomas Tilling bought Stevens in 1910 and the invention was exploited to good effect. However, experience in the First World War taught an increasing number of drivers how to manage a crash gearbox and so the Tilling-Stevens option lost some of its attraction.

In the interwar period the motor car was gaining popularity and the Maidstone based Rootes company had built an astonishing position as the top motor retailer in Britain. They already provided service and repair back up for their sales but expanded this by building charabancs on Tilling-Stevens chassis. As I wrote in How Britain Shaped the Manufacturing World, Rootes explored manufacturing options elsewhere including the Humber company as shown in the image, but also bought Tilling-Stevens in 1950.

In nearby Harrietsham, Marley Concrete roofing tiles were introduced after the First World War when building materials were in short supply. Owen Aisher was building bungalows in Kent, but found he was being held up by supply shortages. He took the initiative and began using an adapted second-hand machine to produce concrete roof tiles. The availability of cement further up the Medway clearly made this cost effective. Manufacturing techniques developed, and a number of factories were built around the country to improve access to customers. By the time of the Second World War, Marley was producing two hundred million tiles a year. In the fifties, demand continued to grow, manufacturing techniques were further developed, and more factories built. Marley added floor tiles, including those made from vinyl to their range. Later, they produced whole roofing systems and more recently integrated solar panels. In 2022, the business was sold with roofing being bought by Marshalls plc.

Medway towns manufacturing history

 Rochester was a cathedral city until local government changes caused the status to lapse on its joining the Medway unitary authority. Nevertheless, its cathedral is the seat of the Bishop of the Rochester Diocese dating back to the sixth century. Rochester boasts a castle whose keep is one of the best preserved in England or France. Rochester has been occupied by Romans, Saxons, Danes and Normans.

Chatham in contrast was a small village on the mud flats of the Medway not far from Rochester and close to Gillingham, Strood and Rainham. It was the mud that attracted naval use. Henry VIII had built the first substantial Royal Navy including the Mary Rose, the first purpose built warship. The Medway then came into its own since the ships could safely be beached and there have their hulls cleaned, caulked and tarred.

Elizabeth I added to the navy, galleys - ships with both sail and oars. These were stationed at Chatham where they could easily be maintained. The dockyard was already bigger than Portsmouth, Deptford and Woolwich and it maintained and improved on this position through the years of war with the Dutch. The yard attracted shipwrights, carpenters, sailmakers, smiths, sawyers, riggers and mast makers.

In the early seventeenth century a new dry dock was built along with mast docks, sail loft and rope house - the latter being 1,000 feet long, the length of the longest rope. The tactic for naval ships was simple, to be massively armed to wreak destruction at short range. The massive PRINCE was an exemplar of this ship type known as the First Rate with three gun decks. These early ships would be armed by cannon cast in iron works in the nearby Weald.

With the eighteenth century came another opponent - the French - and so the centre of gravity for the navy moved westward to Portsmouth and Plymouth. More than this, the theatre of naval warfare moved from the sea between Britain and the Continent to the oceans: the Mediterranean, Caribbean and Atlantic. The ships required for this more open warfare needed to be more agile and so tended to be Third Rate with seventy-four guns or frigates with thirty-two guns. In the course of the century the Royal Navy moved to a position of increasing strength where victory was always expected. This was great credit to the men who sailed the ships and lived in the most appalling conditions, but also to the dockyards.

For Chatham, the eighteenth century meant first completion of the improvement programme, but then decline as resources were directed to Portsmouth and Plymouth. The century ended with restoration ready for the next great conflict: the Napoleonic Wars. At the end of the eighteenth century the Chatham dockyard was the largest employer in the South East with some 2,000 men.

The navy's most famous ship, the VICTORY, was built at Chatham in 1765 and had a chequered career culminating in her being fitted out as a hospital ship in 1797. Two years later she was to be converted into a prison hulk. Instead, orders were given for her to be rebuilt and she left Chatham in 1800 as a superb fighting First Rate ship. These vast ships were built from four thousand oak trees with a compliment of 850 men. The lower of three gun decks was equipped with 42-pounders, the middle deck with 24-pounders and the top deck with 12-pounders giving a broadside of 1,176 pounds. Iron guns were most likely now cast at the Carron works in Falkirk with brass cannon made by Samuel Walker in Rotherham.

The nineteenth century saw reduced employee numbers with the ending of hostilities, but also the introduction of industrial process with a steam-powered sawmill designed and built by Marc Brunel. This incorporated a canal and and overhead rail system, with seasoned uncut timber entering at one end with sawn planks emerging at the other. I wrote in my blog on Portsmouth of Brunel's other inistiative of mechanising the process of pulley production.

The new century also saw the beginning of a dramatic change with steam power taking over from wind and sail. I write in How Britain Shaped the Manufacturing World of the transition from wooden hulls through iron clads to iron and then steel hulled ships. Mid-century saw a major investment in Chatham as it became the only eastern yard with the closure of Woolwich (although its continuance as the army's arsenal) and of Deptford. The work was substantial with new dry and wet docks, repair and fitting out basins all demanding some 110 million bricks made on site from a 21 acre brickfield. As the century drew to a close, ships became ever bigger culminating in the Dreadnaught Class which was too big either to be built or repaired at Chatham.

Her days seemed to be numbered until the Navy decided that they needed to build the newly invented submarines alongside private contractors not least to test their costings. The yard went on to build many submarines alongside Vickers at Barrow. In the Second World War it built smaller surface vessels and refitted a great many vessels of all kinds. At its peak the yard employed 13,000 people from Chatham, Rochester, Gillingham and Strood, and further afield.

The dockyard closed in 1981.

Rochester itself became home to Short Brothers which from 1913 manufactured flying boats or float planes was they were called at their factory at the Borstal end of the city. Their planes served with distinction during the First World War. Shorts survived the slump of the twenties by diversifying into buses, barges and motor boats. They came back into the limelight with the Shorts Singapore which in 1927 made a spectacular flight around the coast of Africa. The thirties saw the Shorts Empire operated by Imperial Airways and offering their 24 passengers a choice of cabins, births and a smoking room. From the design of the Empire came the Sunderland with innovations including a powered gun turret. Many saw service during the Second World War as did the Stirling four engine bomber of which I wrote in my book MacRoberts Reply. In 1943 the company was compulsorily purchased by the government and production dispersed to Belfast away from enemy bombing. With the return of peace, the company moved its operations to Belfast.

BAE Systems Faraday test centre and Advanced Aerospace Technologies are now based in Rochester.

In the nineteenth century Strood became home to Stewart Brothers and Spencer which extracted oil from seeds and sold the residue as cattle feed. Seeds would come by ships from as far afield as India, America and Russia.

Aveling and Porter manufactured agricultural machinery and went on to manufacture steam engines. In the thirties they became part of Agricultural Engineering and joined Barford & Perkins of Peterborough to form Aveling Barford which also took the Hornsby steam and road roller business based in Grantham.

Wingets took the Aveling site to manufacture cement mixers. Strood had attracted cement manufacturers like many sites on the Thames and Medway. Portland cement had become an essential part of building in the mid-nineteenth century. I write more about this in my piece on Dartford.

Gillingham had a history of textile manufacture with the Gillingham Silk Company in business from 1769 to 1875. There was also linen manufacture and glove making. The Copperas Works produced dyes and inks. In the late 19th century the Brennan Torpedo works was established.

Gillingham is also headquarters of Delphi Automotive Systems which had been spun out of General Motors and included AC Delco, Automotive Products of Leamington and Lucas Diesel Systems based in Gillingham. It was bought by BorgWarner which spun it into PHINIA.

Wealden iron masters and gunfounders

 Iron had been produced in Britain since the Iron Age! wherever ore was readily available. Later, in nearly every village there were blacksmiths skilled in moulding the metal.

The Weald in Sussex and Kent was a particularly rich area. In my tour of manufacturing places I had hoped to find a single identifiable place, Heathfield perhaps, but the truth is that the iron works of the Weald were not tied to any town or indeed county. Iron was made where iron was found. There was plenty of wood for charcoal for smelting.

Things changed at the end of the fifteenth century when French iron masters arrived at Buxted with a new technique of blasting air into the smelting process. The air was pumped into the furnace by bellows driven by water wheels and the forging process to make wrought iron then required more bellows to power a large hammer. All this demanded the location of iron works close to flowing water that could be managed in large ponds to power the water wheels for long periods.

Iron works emerged in numbers estimated between 50 and 100 and many took on the skilled task of casting cannon. Periodic battles had been the story of England from time immemorial, with brief periods of peace. So there were blacksmiths who made swords, chain mail and eventually articulated armour. Fletchers made arrows, and bowmen bows. Gun powder was a sea-change. The first cannon appeared possibly in the thirteenth century, but the increased production of iron with blasting enabled more to be cast and the casting process to be improved.

England was moving towards the industrialisation of war.

The use of charcoal meant that the forests were being lost at an alarming rate and Queen Elizabeth had cried halt! She needed the wood for her navy. I write about this in How Britain Shaped the Manufacturing World. The iron masters of the Weald had served their nation well, but the discovery of a process during the seventeenth century whereby coal could be used to smelt iron ore changed all that.

Iron works now moved nearer to coal. Carron in Scotland began to cast cannon at a price much below the Wealden iron masters could match. In the Black Country smelters and foundries came into their own. Telford and Abraham Darby perfection of the process changed everything again and places like Dudley, Wolverhampton and of course Birmingham prospered.

Slowly the Weald's iron masters lost business both from the Board of Ordnance and for pig iron. Nonetheless they had enabled England to win nation defining battles against the Dutch, French and Americans.

Dartford and Thameside manufacturing history

 Dartford in the well-watered, sheltered valleys of the Darent and Cray invited occupation, certainly by the Romans and successive invaders. Over the centuries trades emerged and prospered. One of particular note was the making of paper from rags. John Spilman was granted a monopoly for the collection of rags for paper making. A number of paper mills followed including the Phoenix Mill of TH Saunders noted for the quality of its early machine made paper.

Armament production came to Dartford in the mid eighteenth century in the shape of a gun powder factory. This was succeeded by Vickers, Son and Maxim in the nineteenth century in Powder Mill Lane with an ammunition factory.

In 1889, Burroughs Wellcome took over a former mill for pharmaceutical manufacture and in 1914 built a new factory which was added to over the years reaching some 65 acres and over a million square feet of building. They had 2,800 employees in 1979.

A significant if lesser known manufacturer was John Hall a blacksmith who arrived in Dartford in 1785. By the time of his death in 1836 he had a iron works in Dartford, a gunpowder works in Faversham, a paper mill in Horton Kirby and a flour mill at Chislehurst. One of his apprentices was Bryan Donkin who with Hall built a works in Bermondsey to make tin cans for preserving food. I wrote of this in How Britain Shaped the Manufacturing World. The Hall iron works supplied many local industries: gas works, zinc mills, paper mills and cement works. Of greatest importance was their work on refrigeration. It was said that in the Second World War 37% of the nations storage capacity was cooled by Hall's machines.

In 1886 Halls had installed their first cold air cooling machine on a large cargo ship carrying perishable foodstuffs. At that time Britain was the world's leading importer of food from Australia, South America and elsewhere and so refrigeration was essential. Cold air was better than previous methods but a better solution was needed. In 1889 Halls added carbon dioxide in a two stage compressor. To achieve yet colder temperatures, Ammonia was used and a plant was installed in Grimsby to make ice for the trawler fleet. In 1959, the company merged with Thermotank of Glasgow which made patented cooling and ventilation devices. The merged company bought Vent-Axia of Crawley in 1959 and was itself bought by APV in 1976. It is now part of the Japanese Daikin Group and continues to manufacture in Dartford.

The south bank of the Thames with its reserves of chalk and mud turned out to be the ideal location for cement manufacture.

Lime had been used for millennia in the making of mortar to join stone and brick. The Romans built lime kilns to burn limestone and produce quicklime. Such kilns were to be found across Britain where limestone was to hand. In the seventeenth century it was found that quicklime spread on fields would aid the growth of crops by reducing the acidity of the soil. The demand for quicklime kept growing.

There is evidence that as early as 8,000 BC it had been found that the addition of small amounts of volcanic ash gave the lime the capacity to set under water. In England, John Smeaton, known as the father of civil engineering, building the Eddystone lighthouse discovered that the property of hardening whilst submerged in water was linked to the clay content of the cement. In 1824, a Leeds stonemason, Joseph Aspdin, took this a stage further and invented a method of making from limestone and clay a cement which he called Portland Cement given the similarity in colour between it and Portland stone. He patented his invention and his son William exploited it further setting up a manufacturing plant in Rotherhithe. Other plants followed along the banks of the Thames and Medway using local deposits of chalk and clay taken from the mud of the river banks.

It seems likely that Portland cement was used by Marc Brunel in the construction of the Thames Tunnel in 1828. The story is that Brunel had been using the cheaper Roman Cement patented by James Parker of Northfleet in 1796, but the tunnel collapsed. Tons of Portland Cement were poured in and sealed the tunnel which could then be completed.

Limestone was also used as a flux for the smelting of iron to remove the impurity of silica, which when heated combines with the lime to form slag which is then removed and used for road making.

The exact proportion of lime to clay was crucial and depended on the make up of the local deposits used. The mixing would be either using water or by grinding the dry rocks. In time, cement plants appeared across Britain exploiting local mineral deposits and the availability of coal to heat the mixture until it calcined. In 1845, Isaac Johnson, then manager of the Swanscombe Works close to Dartford, fired the mixture to a higher temperature (1400-1450C) until the mixture clinkered. This was then ground to a fine powder and is essentially the Portland cement we use today.

Cement making was a dirty process and the towns folk complained. Johnson though went ahead with larger works at Greenhithe. In time there were some thousand kilns along the banks of the Thames and Medway.

In 1900 the Associated Cement Manufacturers Company was formed bringing together some twenty four companies all but two on the Thames and Medway including two of the early plants Robin's and Swanscombe. This company became Blue Circle Cement and is now owned by the French Lafarge.

Erith manufacturing history

 Erith was not on Watling Street (unlike neighbouring Crayford) and so until the arrival of the railways it was restricted in industrial activity to that enabled by the Thames, so brick works and loam quarrying principally to provide ballast for ships.

The first manufacturing industry was the engineering factory of Easton, Amos and Anderson in 1864; the last named being also Director General of Ordnance Factories and I wrote about him in the context of the modernisation of the Royal Arsenal at Woolwich. The factory closed in 1904 but left well made pumping engines some of which were still working after the Second World War.

A significant early industrial newcomer was the Callender Bitumen, Telegraph and Waterproof Company in 1880. At this time electric cables were being run for telegraph and soon power transmission. A little further upstream at Woolwich, Siemens was much involved in the same area. The company became Callenders Cable and Construction Company and in 1945 merged with British Insulated and Helsby Cables itself a product of the British Insulated Wire Company which had been founded in Manchester in 1890 by Sebastian de Ferranti, Colonel Pilkington of St Helens and others. British Insulated Callender Cables or BICC (as the combined company became) and its predecessors can claim credit for much of the national grid. In 2000 BICC changed its name to that of its construction subsidiary Balfour Beatty. It had previously disposed of its cable interests.

In 1887, the Nordenfeldt Gun Company built a factory in Erith and a year later combined with Maxim at Crayford. The combined business was then bought by Vickers. The business was renamed Vickers, Sons & Maxim and manufactured many machine guns during the First World War including the heavy 'PomPom' which had been used in the Boer War. Production was moved to other Vickers factories in 1932.

Fraser and Chalmers were to be another Erith manufacturer. They had originated in the USA and had focused on the manufacture of mining machinery. They set up in Erith in 1891, but by 1903 severed all US connections and expanded their range of products into steam plants, milling machinery and general engineering. In 1918, the business was bought by GEC and its was repurposed into manufacturing turbines. In the mid twentieth century it employed 4,000 people in a site extending to thirty-four acres.

Turner's Asbestos Cement Company set up in 1912 to manufacture asbestos roofing material, guttering, piping and fireproof and thermal insulating material. The company was owned by Turner and Newall of Manchester. The subsequent discovery of the dangers of asbestos effectively ended the business.

Continuing with construction, Royal Doulton Potteries made salt glazed stoneware piping. British Plaster Board processed imported gypsum. The Hercules Powder Company and Borax Consolidated Ltd provided raw materials for glass enamel and pottery.
