East London manufacturing history 19th and 20th centuries

 

Docklands

The first decade of the nineteenth century saw an expansion in docks which would guarantee London's position as the world's trading city. The first was a West India Docks which had in addition to the docks themselves, warehouses all surrounded by a secure wall. The work was privately funded and financed by a 21 year monopoly of West Indies trade. They were located on the then marshy Isle of Dogs. Next came London Docks serving Europe and North America located in Wapping. Lastly the East India Company opened their walled and policed dock at Blackwall.

The East India docks speak of the vast international trade that poured through London and I am drawn to John Masefield’s poem Cargos which I quote at the start of How Britain Shaped the Manufacturing World. I also remember from childhood sailing from the docks on a banana boat bound for Tenerife.

We are still talking of ships made of wood and powered by sail for which London shipbuilders were rightly famous. Anthony Slaven in his book British Shipbuilding 1500-2010 suggests that eight major yards on the Thames were in the van in building iron hulled ships. These yards had the skills in shipbuilding but also engines. The 1860s were a boom time for London's yards with at one time as many as 27,000 people employed in shipbuilding. 1860 saw the first British ironclad, HMS Warrior, built by the Thames Ironworks, clad with armour by John Brown and armed with guns from Armstrongs. The boom came to a grinding halt as the Clyde, Tyne and Tees took over the lead largely because raw materials were close by and so vastly cheaper that those London shipbuilders had to buy in. I write in another blog piece of Henry Maudslay's influence on machine tools; his company Maudslay Son and Field were highly influential in steam power for ships. In Greenwich, John Penn owned the largest marine engine business in Britain.

In shipbuilding 1,700 worked in John Penn’s boiler works at Greenwich and many more at Wigham and Green’s yard at Blackwall.

Joseph Rank saw the vast quantity of grain imports coming through London docks and saw the opportunity for flour mills which he built by the river. These worked alongside huge warehouses and markets. London had cornered world trade, for example Australian wool was shipped to London for onward sale. The domination in trade was mirrored and amplified in banking and finance where London took an unassailable lead until 1914.

The docks needed expanding again, this time to fit the larger steam powered steel hulled ships and the Victoria and Albert docks were built.

The final expansion of the docks on the Thames can look to Tilbury docks in 1886 which provided a massive deep water dock east of the then docklands. Somewhat later Samuel Williams created a huge industrial development around Dagenham Dock. Tilbury would once again take the lead in 1967 in the move to containers which transformed the docks from a community ruled by dockers to an international business controlled by computers.

Woolwich

Woolwich was of course home to the Arsenal where some 75,000 worked in 1917 and I write of this and more in Ordnance and How Britain Shaped the Manufacturing World. At the start of the Crimean War an engineer, John Anderson, was appointed to undertake a major programme of modernisation and expansion. He introduced steam power into the Foundry and the Royal Carriage Factory. Similar building programmes and modernisation were undertaken at the Royal Small Arms Factory at Enfield, which had been set up after the Napoleonic Wars following bad experience with commercial suppliers, and the Royal Gunpowder Factory at Waltham Abbey. Another key appointment was made in 1854, when Frederick Abel took the office of Ordnance Chemist which had fallen into disuse in 1826. Under Abel, the technology of ammunition took major strides with Woolwich as a centre of excellence.

William Siemens was another major employer in Woolwich. As I write in How Britain Shaped the Manufacturing World, William was the British end of the German family and took on the manufacture of cables for telegraph. In time cables crossed the globe with Siemens purpose built ship The Faraday laying them. Siemens worked in partnership with steel rope makers, Newall & Company of Newcastle. This latter company became part of British Ropes which later changed its name to Bridon. Siemens factory became part of GEC but was closed by Arnold Weinstock attracting acrimony from the community and unions. The factory had also produced telephone equipment. As well as hand-sets, they supplied their first public automatic telephone exchange in Grimsby in September 1918 handling 1,300 lines. This was followed by exchanges in Stockport, Southampton and Swansea; in all some forty-three out of one hundred exchanges brought into service by the Post Office up to 1927. They also set up exchanges in Canada and Australia. Such was the demand that they took new space in Hartlepool and Spennymoor.

In the Second World War in order to protect the Clyde, Siemens were commissioned to supply not only the five miles long loop cable through which high currents would be passed to explode such mines, but to commission and build all the necessary switch-gear and power plant. They also supplied cables equipment for radar and line communications. They were of course the perfect company to produce a submarine cable which could contain petrol at high pressure for the PLUTO project. For the HAIS pipeline (Hartley, Anglo-Iranian, Siemens) cable of seventy miles in length was required and a whole new building had to be constructed to contain it. Elsewhere, lamp production became even more specialised for the war effort, and the research laboratories were kept busy with demands by the British Aircraft Establishment for specialist bulbs for aircraft signalling.

Shoreditch and Bethnal Green

The furniture trade continued stongly into the nineteenth century. Timber would be provided from local saw mills such as Lathams which prospered and is now a leading UK timber supplier. One or two larger establishments emerged. In the lead was Lebus, but Hille and others would follow. Herrmann was said to have the largest furniture business in Europe; they were also in New York. The Lusty family made Lloyd Loom furniture.

It was a mixed economy with some warehouses making space for manufacturing. West End retailers, like Maples, began to source their products from East End makers. The large hire purchase companies like Times and Great Universal Stores dealt with the warehouses and the larger makers. Mechanisation came with electricity and, with the establishment of the National Grid, larger makers took advantage of cheap land in the Lea Valley, leaving little furniture making in the East End. When Lebus moved they had 1,000 employees. They now manufacture in Scunthorpe. Hille, which employed two of Britain's most talented designers in plastic injection moulding, moved to Watford and now manufacture in Ebbw Vale. Meredew moved to Letchworth.

Barking, Silvertown, Dagenham and Shadwell

Barking had an unhappy start to industrialisation. In How Britain Shaped The Manufacturing World I wrote in the context of communication of the great stink, the Thames doubling up as a massive open sewer. The river attracted all sorts of industry and processes often highly polluting especially outside the county boundary where by-laws restricting offensive trades did not apply. In Barking this meant chemical and related industries. Barking's other problem was that the sewerage from north London carried by Bazalgette's new sewer emptied to the west of Barking creek, creating, along with market gardens (where some of the sewerage was used raw as fertiliser) and polluting industries, a massive public health problem. In time local authorities were established which could enforce regulations and act together to improve the environment with sewers but also railways and means of communication. J.B.Lawes discovered a method of making fertiliser from treated sewerage, thus overcoming the health hazards.

The coming of the railways opened up east London and Essex for development. Barking attracted the largest gas works in Britain and much later a massive coal fired power station. Handley Page’s first aeroplane was made in Barking. After the First World War a number of new companies opened factories: P.C. Henderson doors (subsequently relocated to County Durham and now part of the Finish ASSA Alloy company), A.F. Bulgin radios and Dicky Birds crackers and ice-cream. Abbey Match works became part of the British Match Corporation.

In the Second World War, Barking creek was used for building Mulberry Harbours; companies in the borough also produced chemicals, life jackets, wood craft including Mosquito aircraft, and steel drums.

The local authority built the largest council house estate at Becontree which leads on to....

Dagenham which became home to Ford UK which moved manufacture from its plant in Manchester; many employees from Manchester moved into the Becontree estate. The Dagenham plant was vast with its own furnaces for casting engine blocks. One of their paint suppliers, Lewis Berger, was at nearby Shadwell Heath (I remember well working on their audit in the seventies). Dagenham also had an industrial alcohol distillery run by the Distillers Company, a May & Baker factory and pharmaceutical research facility drawing employees also from the Becontree estate.

Whilst most manufacturing still took place in the home or in small workshops, Jerry White highlights some of the other larger factories. Silvertown had a factory employing 3,000 making tyres and footballs, and insulation from rubber. The company The India Rubber, Gutta Percha and Telegraph Works Company was bought by the American Goodrich who then sold it to British shareholders and it became the British Tyre and Rubber (BTR). The insulation was probably used by Siemens Brothers at Woolwich which employed 1,700 making cables. Rope making took place in Shadwell with Frost’s works being the largest in the world.

At the start of the twentieth century the Great Eastern Railway employed 3,100 at their Stratford works. The workshop was originally intended for repair, but went on to build locomotives. Their famous engineer James Holden built an early electric powered locomotive capable of reaching 30mph in 30 seconds. It never went into service for the rail infrastructure at the time was not up to the challenge.

Bryant &  May employed 1,400 in Bow making matches. Bow was also home to porcelain manufacturer Thomas Frye and Edward Lloyd's paper mill. The paper industry blossomed following the abolition of the newspaper stamp in 1855.

Plessey had their main factory was at Ilford and relocated during the war to Central Line Tube tunnels to escape enemy bombing. Ilford manufactured photographic film here. Britvic manufactured soft drinks in Beckton.

Ilford manufacturing history

 The manufacturer of photographic film that shares the name of the town was founded in 1879 and moved to a larger factory in Basildon in 1976

Plessey had started out in Marylebone in London after the First World War as mechanical engineers exploiting the talents of a German born engineer, William Oscar Heyne. The first products were jigs and tools. In 1919 the company moved to Holloway with investment from American, Bryan Clark.

Marconi, through their Marconiphone company, produced valve receivers, but not many. They subcontracted manufacture to Plessey and the relationship continued successfully until Marconi established their own manufacturing in 1926, and Plessey reverted to component manufacture. In 1923 Plessey had moved to Ilford where they also manufactured telephone equipment and equipment for the RAF and motor manufacturers. In 1929 Plessey made the first television invented by John Logie Baird. They also made the first portable radio. Bryan Clark's son, Allan, introduced mass production of standard components.

Plessey took on licences to produce American aircraft equipment. In the Second World War, Plessey produced many different types of components and equipment for the war effort, including shell cases, aircraft parts, and radio equipment such as the R1155 (receiver) and T1154 (transmitter). Following bombing of their Ilford factory they moved production to unused sections of the Central Underground Line. They also opened a factory in Swindon and took on the management of shadow factories. They set up a research establishment at Caswell House near Towcester. At the end of the war they employed 11,000 people, a workforce which reduced with the coming of peace.

Allan Clark's sons, John and Michael joined the company and senior managers, John Cunningham and Raymond Brown, left Plessey to form Racal. The company made many thousands of television sets for EMI. With the growth of the hydraulics business, the company formed two separate divisions, Fuel Systems which was moved to Titchfield, Hampshire and Industrial Hydraulics which went to Swindon, Wiltshire.

The next break came with telephones. The existing system, Strowger, was ‘hopelessly out of date’ and the development of electronic exchanges still some way off. The answer was the Crossbar system which AT & E had developed. Plessey bought both Automatic Telephone & Electric (with their Liverpool and Bridgnorth factories) and Ericcson, taking over the Beeston factory, and won twenty-six out of the thirty-two orders placed. I write of this in Vehicles to Vaccines.

In 1961 the company had 17,500 employees. Six years later the payroll had grown to 68,000 employees with 6,500 in research and development with R&D labs at Caswell in South Wales, Roke Manor near Romsey, Taplow in Berkshire and Havant and Poole in Hampshire and Dorset.

Plessey were important suppliers to the Ministry of Defence and I write of this in my piece on Kingston upon Thames and Isle of Wight. Plessey made a failed bid for English Electric in 1968. In the eighties they went head to head with GEC over the next generation of telephones. In the event it was Ericcson which won with their System Y as opposed to System X which was developed by Plessey and GEC. Through the machinations of corporate bids, the Plessey telecoms business ended up with Ericcson and its defence related business eventually became part of BAE Systems via its merger with Marconi (the new name of GEC). I also wrote of this in Vehicles to Vaccines.

One part of Plessey did survive intact in Plymouth as Plessey Semiconductors which also took in Marconi Semiconductors.

I am grateful to Graces Guide which supplemented the earlier research I did for my books How Britain Shaped the Manufacturing World and Vehicles to Vaccines.

Plymouth manufacturing history

 Set on the western approaches, Plymouth was in many ways Britain's door to the wider world. It was from Plymouth that so many of our adventurers sailed: Sir Francis Drake to the Pacific, the Pilgrim Fathers to America, James Cook to Australia and Charles Darwin to the Galapagos. I have written separately about our adventurers and explore in How Britain Shaped the Manufacturing World their role in the beginnings of the Industrial Revolution.

In the later seventeenth century the city became home to a Royal Dock known now as Devonport. The docks built many hundreds of ships and maintained the fleet. In the nineteenth century it was subject to a major extension to allow for larger ships, also the Royal William Victualling Yard was built. The Great Western Railway was linked to the docks. A regular domestic service to Brittany began. The Royal Dockyard in 1912 employed 12,000 civilians. The biggest vessel ever constructed in Devonport was the 30,600 ton Warspite launched in 1913.

Other industries arrived. Isaac Reckitt took over a Plymouth factory in 1905 and made Robin starch and washing powders. Bryant and May experimented making lucifer matches. Their factory burnt down and they moved to London to make Swan Vestas. Lever Brothers developed a presence in the city by buying soap companies.

War time bombing left Plymouth with gaping wounds and the great task of reconstruction began as early as 1942. Reckitts had been bombed and decided to concentrate their activity in Hull. Companies were encouraged to set up: C&J Clark, Slumberland mattresses and Browne & Sharpe machine tools arrived in the fifties. Tecalemit were in production by 1948 as were Berketex dress makers.

Plymouth attracted electronics companies. It is home to Plessey Semiconductors. Bush Television built a factory in Plymouth to expand on its west London premises. BAE Systems have a Systems and Equipment establishment in the city.

A good number of American owned companies have bases in Plymouth and work in life sciences, composites and other technologies. Mars Wrigley make gum in the original Wrigley factory. You can read more detail in this link to research carried out by students in Plymouth.

Burts Crisps was founded in 1999 by Richard and Linda Burt with premises in Kingsbridge. They moved to a bigger factory in Plymouth in 2006.

Kawasaki Precision Machinery has been making hydraulic equipment in Plymouth for 25 years.

The work of the former Royal Dockyard has now been passed to Babcock International at Devonport and Rosyth. Princess Yachts were founded in 1965 and manufacture high class yachts sailed the world over
