1920 Jan. Physical and Optical Societies Exhibition. Exhibitor of electrical instruments. [19]

1937 Electrical and mechanical instrument makers. [20]

Post WWII The number of employees at Lewisham reduced about 4000 to under 1000.

1946 Due to the company’s long-standing provision of analogue computers for naval fire control, the Admiralty decided to set up an Elliott Research Laboratory in a redundant fuse factory at Borehamwood, tasked with developing an innovative ship-borne anti-aircraft gunnery predictor. The head of the laboratory was John Coales. The Admiralty contract stipulated that the project was to be digital rather than analogue (a far sighted decision).[21]

1946 Elliott Brothers and B. and P. Swift were allocated space in the Shorts' factory at Rochester. Elliotts would employ about 500 on all types of electrical and mechanical precision instruments. Swifts will employ about 450 on automatic scales, gears and hydraulic pumps.[22].

1947 The company merged with the weighing machine manufacturers B. and P. Swift; Leon Bagrit, the founder of B and P Swift, became joint managing director of Elliott Bros.

1950s the research laboratories at Borehamwood consisted of seven divisions, two of which were developing digital hardware - Computing, and Circuits. In addition there was a small Theory Group.

The real time computer upon which Coales’ team worked was called the Elliott 152. It had a multiply time of 60 microseconds and first ran a program in 1950. For comparison, the American Whirlwind real-time computer first ran a program in 1951 and had a multiplication time that varied between 36 and 44 microseconds.

1950 The first Elliott real time computer, the 152, was put into operation; this was intended to be the Admiralty's anti-aircraft gunnery predictor.

1951 NRDC gave Elliott Bros a study contract to consider whether their constructional technique could be applied to something like a re-engineered version of the Manchester University computer. Eventually this led to a proposal for the development of a packaged computer. NRDC agreed to pay for the development and construction of a prototype - which became the 401.[23]

Leon Bagrit negotiated with the National Research Development Corporation for a contract to produce a small, reliable digital computer that would complement the much larger Ferranti Mark I machine.

1952 The prototype 401 computer was sent to Cambridge and then to Rothamstead.

1952 Members of the Theory Group conceived a general purpose stored program computer to meet the requirements of an RAE computing project; the machine was later called Nicholas. This played a significant part in the design thinking behind ferranti's Pegasus computer[24]. At the same time, several analogue computers were developed at Borehamwood.

1953 Aviation Division was formed at Borehamwood; this formed the basis for Elliott Aviation

1953 After a difficult few years post-war, whilst the company was being redirected from armaments work to civilian products, Elliott Brothers had made profits in 1951 and 1952. It now took the opportunity to raise funds for investment with the issue of new shares. It was noted that Bendix Aviation Corporation had recently subscribed for shares at twice the par value.[25].

1954 Elliott Brothers acquired Bristol's Instrument Co to strengthen its process control activities[26]

1957 Elliott Automation issued shares to the shareholders of Elliott Brothers and Associated Automation to effect a merger of the 2 companies, forming 'the largest automation and instrumentation company in Europe'. Elliott Brothers continued to exist as a subsidiary company of the Elliott Automation Group.[27]. Leon Bagrit became deputy chairman and managing director.

1958 Associated Insulation Products subsidiary sold to Associated Electrical Industries (AEI).

1959 Elliott Nucleonics formed as subsidiary company.

1960 Bendix Corporation sold its remaining shareholding in Elliott Automation

1960 The computer scientist, Sir Tony Hoare, was an employee from August 1960 for 8 years. He wrote an ALGOL 60 compiler for the Elliott 803 and also worked on an operating system (Elliott 503 Mark II), although this was less successful and abandoned along with "over thirty man-years of programming effort."

1961 Electrical and mechanical engineers, manufacturing fire control apparatus, precision and electronic equipment for H.M. Ships and instruments and equipment for aircraft. Commercial products include measuring and control instruments, control valves weighing and food preparing machinery and hydraulic pumps. 5,500 employees. [28]

1961 Firth Cleveland Instruments was purchased by Elliott Automation; business would continue from the same site under the name Elliott (Treforest).

1962 Leon Bagrit knighted.

1963 John Lansdown pioneered the use of computers as an aid to planning; making perspective drawings on an Elliott 803 computer, modelling a building's lifts and services, plotting the annual fall of daylight across its site, as well as authoring his own computer aided design applications.

1964 Two new management divisions formed - Mechanical Automation and Elliott-Automation Nucleonics - bringing the total to 14 business divisions in the Group.

1967 In the first deal arranged by the Industrial Reorganization Corporation, English Electric Co took over Elliott Automation to form the leading European group in computing and process control.

1968 Supplied plug stringers for the Winfrith power station. [29]

1968 English Electric Computers Ltd was taken over by International Computers and Tabulators (ICT); this marriage was forced by the British Government, who believed that the UK required a strong national computer company. The combined company was called International Computers Ltd (ICL). English Electric Co retained the military and industrial automation activities of its Marconi and Elliott Automation subsidiaries.[30].

1968 GEC took over English Electric Co

1969 GEC reorganised the businesses it had acquired from Elliott Automation, English Electric Co, AEI and Marconi. In electronics, GEC-Marconi Electronics was created with 4 subsidiaries Marconi-Elliott Avionics Systems Limited, GEC-Elliott Space and Weapons Systems, Marconi Communications Systems and Marconi Radar Systems.[31]. GEC-Elliott Automation comprised the automation and control activities of the predecessor companies.[32].
