of high-level programming languages. For a contract to produce the autocode for the Ferranti Orion computer, Strachey hired Peter Landin who became his one assistant for the duration of Strachey's consulting period. In 1962, while remaining a consultant, he accepted a position at the University of Cambridge. In 1965, Strachey accepted a position at the University of Oxford as the first director of the Programming Research Group and later the university's first professor of computer science and fellow of Wolfson College, Oxford. He collaborated with Dana Scott. Strachey was elected as a distinguished fellow of the British Computer Society in 1971 for his pioneering work in computer science. In 1973, Strachey (along with Robert Milne) began to write an essay submitted to the Adams Prize competition, after which they continued work to revising it into book form. Strachey can be seen and heard in the recorded Lighthill debate on AI (see Lighthill report). Strachey contracted an illness diagnosed as jaundice which, after a period of seeming recovery, returned and he died of infectious hepatitis on 18 May 1975. Strachey developed the concept of time-sharing in 1959. He filed a patent application in February that year and gave a paper "Time Sharing in Large Fast Computers" at the inaugural UNESCO Information Processing Conference in Paris where he passed the concept on to J. C. R. Licklider. This paper is credited by the MIT Computation Center in 1963 as "the first paper on time-shared computers". He developed the Combined Programming Language (CPL). His influential set of lecture notes Fundamental Concepts in Programming Languages formalised the distinction between L- and R- values (as seen in the C programming language). Strachey also coined the term currying, although he did not invent the underlying concept. He was instrumental in the design of the Ferranti Pegasus computer. He was a pioneer of early video games creating a version of draughts for the Ferranti Mark 1. The macro language m4 derives much from Strachey's GPM (General Purpose Macrogenerator), one of the earliest macro expansion languages. Legacy The Department of Computer Science at the University of Oxford has a Christopher Strachey Professorship of Computing, currently held by Samson Abramsky FRS. In November 2016, a Strachey 100 event was held at Oxford University to celebrate the centenary of Strachey's birth, including a viewing at the Weston Library in Oxford of the Christopher Strachey archive held in the Bodleian Library
