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

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.

Farnborough manufacturing history

The Factory, as the Royal Aircraft Factory was known to the early aircraft manufacturers, came to Farnborough as the Army School of Ballooning which had been formed at Woolwich during the Boer War and then moved to nearby Aldershot before coming home to Farnborough with the formation of the Army Balloon Factory.

In the early days its mission was to try to impose safety standards on the reckless adventurers who were the first to take to the air. When the Wright Brothers succeeded with powered flight the army turned its attention to the marriage of aircraft and the internal combustion engine and the Royal Aircraft Factory was born.

All this came just in time for the First World War and initially the use of aircraft for reconnaissance. The Factory came up with designs alongside the commercial manufacturers and, as I suggest in How Britain Shaped the Manufacturing World, played leapfrog with the Germans, and aeroplanes became ever more technically advanced. I write about this in my chapter on the First World War.

The interwar years presented something of a hiatus of aircraft design until re-armament began. The Factory was once again up with the pack in aircraft design.

After the Second World War, the British aircraft industry was vast but, unlike the Americans and Germans, relied too much on old technology. The Royal Aircraft Establishment as it had been renamed was tasked with the challenge of leading the drive to ever more advanced technology. We were at war, but it was a Cold War demanding a whole different approach.

In 1962 the Establishment employed 8,500 people including 1,500 scientists.

This remarkable team of people tackled a good number of knotty problems.

  • jet lift and the control of vertical takeoff aircraft, culminating in the Hawker Harrier
  • supersonic interception aircraft culminating in the English Electric Lightning
  • the V bombers
  • the enquiry into the Comet crashes to understand why it happened and how it could be avoided in future
  • Concorde and supersonic transport, employing the wind tunnels to full effect.

The site comprised a range of buildings:

  • Q121 24ft wind tunnel
  • R133 Transonic wind tunnel
  • R52 1916 wind tunnel building
  • R136 11.5 ft x 8.5ft wind tunnel
  • R178 Materials and chemistry building
  • R51 Forge and Foundry
  • Q120/Q146 Seaplane test tank
  • R173 Romney buildings
  • Q134 Weapons testing building
  • Q65 The fabric shop
  • Q170 Telephone exchange
  • Q153 Structural test building

The site was decommissioned in 1998 and had been redeveloped as Farnborough Business Park. However the legacy was preserved to an extent in the air tunnel buildings owned by the Farnborough Air Sciences Trust, a museum in the Balloon Factory named Trenchard House and a massive portable airship hangar. There is of course the annual Farnborough International Airshow held at the Farnborough International Exhibition and Conference Centre.
