The Lyons Electronic Office (usually referred to by the acronym, LEO) was a computer built by Lyons, a British chain of cafeterias; the first computer ever built for business applications.
It was a brave and audacious start for a company that ran corner tea shops; they decided in 1949 to investigate the computer for their office functions. Their work showed the path to the adoption of computers in businesses - the first non-mathematical task to which they had been put.
The design of their first computer, retrospectively named the LEO I', was based on the EDSAC; an engineer from Lyons was seconded to the EDSAC project, and helped build it.
There was a public announcement in "Electronic Engineering" of its running in production in April 1954, but it had at that time been under test and doing some government work for 18 months.
It was so successful that Lyons set up a subsidiary, Leo Computers, to build more of them.
The increasing capital requirements to build computers eventually resulted in Lyons' computer business being merged with English Electric Computers in 1963 (Lyons exited in 1964); English Electric itself was later merged into International Computers Limited.
