Elliott Automation

 

In the last few months I have worked my way from the Thames all the way up the east, the Greenwich bank, of Deptford Creek and the Ravensbourne River and, following my piece on the Anchor Brewery last week we are nearly at Lewisham Bridge.  I think it’s now time to turn round and work back down the Lewisham bank of the Ravensbourne, the west bank and get back to the Thames and I hope it’s going to be an interesting journey.

 

Let’s start off with the first big site coming down the river . That was a factory making a lot of interestingly new tech, although it was quite an old firm .They were in the huge Century Works - in the triangle of the Ravensbourne where there is now newish houses along what is now Armoury Road. When Century Works was built this was previously unused marshy meadow and the firm built it was something to be reckoned with.

 

Arpound 1965 I was working as a copy typist for the Buyer in a Dartford factory. The Buyer was a nice young chap who was always telling me about the Rolling Stone whose parents lived just down the road from him. As ever I was told nothing about the Company I was working for – no one in these offices can ever comprehend that the ‘girls’  - the typists - could ever be interested in, or understand such things. I had the impression that what they made was deckchairs - and I’m sure that these were much more profitable than the technical instrumentation with which the company had made its name and then still claimed to make and sell.  However a rumour went round that we had been taken over by another company.  One day the top manager came in with a lot of forms which he said we would need to complete in the future. He was moaning and moaning about them, on and on   - about how the new owners were making them do these silly extra jobs.  Quite honestly it was all very basic management stuff but he was confused – and so resentful.   I later learnt the firm who had taken us over and was going for efficiency was called ‘Elliotts’.

 

One of the industries that gets a bit missed out in accounts of the ‘industrial revolution’ is the making of instruments - the many devices which keep the world measured and monitored; makes it work and keeps it under control. Around the turn of the 19th century there were several firms which were set up to make all sorts of clever bits of equipment.  One, of course, particularly relevant to Greenwich, was the making of telescopes, and also navigation instruments – for istanxe sextants were made in their thousands in New Eltham by Stanleys, and every naval officer had to have one, 

 

William Elliott had opened his first shop in 1817 describing himself as an ‘instrument maker’ in Goswell Street, north of the City in London. By 1824 he was in St. Martin’s Lane in business as an optician. This was quite a common way of starting and skills learnt with lenses could be transferred to other devices as necessary.  In due course William took his two sons, Frederick and Charles, into partnership - hence the company was to become ‘Elliot Brothers’.  He died in 1853 and his sons began to make instruments for surveying railways and related applications. For instance they were advertising a patent ‘electric galvanic pocket battery for personal medical use’ and as the 1850s progressed, other electrical apparatus.

 

Elliott Brothers moved to Charring Cross to an ‘excellent and commanding shop’. This was a double fronted shop with a counting house and workshops.  They were then described as mathematical instrument makers and advertised the invention of a wooden drawing board with a means of preventing it ‘warping and twisting’. Frederick patented "an improved case for aneroid barometers for marine purposes.’ They exhibited in Paris a range of ‘mathematical, optical and philosophical instruments’.

 

By 1870 Elliotts were employing 150 men but still described themselves as ‘opticians’. At an 1876 "Conversaziones" of the Society of Telegraph Engineers they exhibited more than seven different instruments. These included - condensers designed by a Royal Engineer, an Electrometer adapted from Sir William Thomson’s original, and a Replenisher, for use with quadrant electrometer, Resistance Coils for use in India, a Strophometer, for showing and recording the number of revolutions of machinery – and this could to be used on the paying-out gear of a cable-ship. Clearly this was an area important to workers in the Greenwich based telecommunications industries.  The exhibits were said to show ‘all the scientific accuracy and beauty of workmanship for which that firm has so great a name’. Elliot’s had established a works to produce telegraphic equipment in Saint Martin’s Lane off Charing Cross. Eventually this branch of their work was to be transferred to Siemens

 

By 1882 the Elliot brothers had both died and although the firm continued to keep them in the company name there no more Elliotts involved. By 1894 the firm was involved in specialist military and naval work and were making electrical signal equipment for warships. The list of the devices which they made and sold had become much longer..  

 

In 1900 they moved to purpose built premises in  Lewisham – Century Works. Here they produced instruments for telegraphy, electrical engineering, surveying, metrological, marine and more.  They had a staff of about 300 and around the same time acquired a Royal Warrant.

 

The company began increasingly to concentrate on instrumentation for military systems – as well as for vehicles in general.   I note advertisements from the 1900s for ‘speedometers’ for road vehicles –something we would regard as an essential device speedometer. These were offered for sale and included an encouragement to people to buy them for Christmas presents for the motorist in your life.

 

With the government scientist, H.E.Wimperis,  they began to manufacture an accelerometer which he had invented and which measured acceleration and became an important device for testing locomotive and motor-vehicles.  By 1912 they were supplying flight instrument panels and aircraft instrument to the War Office and others. Through this they began to be involved in aircraft instrumentation working on a gyro turn indicator and increasingly developed equipment for aircraft engines. They undertook experiments for devices for use in aerial bombing and patented an optical speedometer, an aircraft rate of roll indicator, and a bomb sight for the Admiralty. They produced equipment for ships' logs, gyro-compasses for use on battleships, Wimperis accelerometers and gradiometers, all kinds of speed indicators, recorders and switchboard instruments, telegraph apparatus etc.

 

Today we look at the days of the early aircraft and tend to see its development in terms of the shape of the aircraft and the techniques of the actual flight.  But this instrumentation was vital for its success and tends to be taken for granted.  They produced tachometers advertised for aircraft engines - one of which Tommy Sopwith used on a 1910 record flight to Belgium.  Their expertise in making barometers let to the development of an altimeter. They worked with Short Brothers, who had established the first aircraft factory in the world Rochester where aeroplanes were made, based on Wright Brothers designs. (We all remember the sea plame moored alongside Rochester Bridge in the 1940s and ‘50s – don’t we?) 

 

A panel of Elliott instruments was offered to customers. They advertised in the new magazine – ‘Flight’ - who enthused about the instrument board and the need for a standard instrument panel like this for all aircraft. It included an altimeter, an airspeed indicator, an ascent/descent indicator, a clock and a tachometer.  It seems beyond belief now that this was not considered essential from the start!

 

At Lewisham in the Great War Elliotts produced a huge volume of aircraft instrumentation and staff numbers rose accordingly. They made airspeed indicators, engine tachometers, clinometers to Farnborough designs as well as altimeters and fuel flow equipment. These were produced in their thousands. They also made machine gun sights to Wimperis' designs.  Many staff were employed on naval fire control equipment. This continued through the 1920s and 1930s with work on Naval gunnery systems and they expanded into control instrumentation and eventually computers for every conceivable type of industry.

 

By the Second World War Elliot’s were employing several thousand people at the Century works. They made naval fire control equipment and electrical and electro-mechanical apparatus for the military and the government departments.   In 1940 an additional building was erected on the Lewisham site by the Admiralty - designed to be bomb resistant. It was used for the design and manufacture of Naval fire control - gun control systems – and associated equipment. Although they were surrounded by areas subject to heavy bombing damage to the factory was limited. 

 

When the war ended the naval work ended with it and eventually a new set of managers arrived who were to move the company into the late 20th century.

                                                                                                                            

In 1946 the company opened a research laboratory at Borehamwood.   This was a significant force for many new industries for Britain and it made important contributions in military radar, industrial instrumentation and the emerging world of digital computers.  

 

People today will find it difficult to realise that in the immediate postwar period through into the 1960s Britain was the leading country in the computer industry. The first business computers were developed in London and many people will know the story of how Lyons, the cake and ice cream making giant, also managed to invent and sell the Leo – the first commercial business computer. The world’s first real-time computer with memory store was built by Elliott’s in Borehamwood in 1947.

 

By the 1960s Elliotts were world leaders in manufacturing computers which conceivably could be used and understood by ordinary people - although these were huge devices which would take up a whole specially built room. The Elliott 401 was the first working machine to be developed in the UK and was the first of a series of digital computers produced by the firm over the next 20 years.  Elliotts were one of three or four companies making this equipment but were to be taken over by US based companies who built on the technology developed in Britain to take over world markets. British computer development was based on university and related research – while the Americans knew about business applications like punched card apparatus, and had marketing know-how.  I suppose I could also add that the same thing happened around the same time with the aircraft industry where Britain led the world in innovation and manufacture – with, for instance, the Comet  - to see American giants move in, copy and take over. 

 

In 1953 an Aviation section was opened at Borehamwood.   A site at Rochester Airport had been used by Shorts and 1962 Elliott Automation began to expand there developing airborne digital systems for Airbus and Boeing.   Meanwhile in Lewisham, through the 1950s,  the electronics division manufactured devices pioneered at Borehamwood and a Nuclear Reactor Control Division was set up there.  This includes specialist computers and simulators as well as process control instrumentation.   Lewisham Library's archive holds a collection of trade brochures from Elliotts giving many, many devices made at Century Works after the Second World War.  Most of them are for uses incomprehensible to most people but which involved measurement and process control for industrial applications.

 

Elliot’s were taken over in 1968 by GEC and Century works finally closed in 1989. The factory was eventually demolished and is now the site of housing. A book which described Elliot’s work which I have promised to mention is Moving Targets: Elliott-Automation and the Dawn of the Computer Age in Britain, 1947 – 67 by Simon Lavington.  There are also number of websites which give quite a lot of detail.  For a long time I have tried to get a speaker for Greenwich Industrial History Society on Elliott’s and have failed completely although I did almost get someone once from the Rochester division. 

I’ve known about Elliotts for a long time and very sorry that their role in the computer world, along with other British firms ceased as the American giants moved in.  I suspect Elliot survived as long as they did because their base always was in industrial world rather than business. We should remember that all the things we take for granted in our cars and computers is based on the technical expertise on developing that instrumentation. Elliotts was a firm we should be proud of and reminds us of a time when Britain led the world in much ‘new tech’.
