Lucy Joan Slater

Lucy Joan Slater (born January 5, 1922 and died June 6, 2008) was a mathematician who worked on hypergeometric functions, and who found many generalizations of the Rogers–Ramanujan identities. In the early 1950s she played a leading role at Cambridge University in devising a precursor of modern computer operating systems, and subsequently she helped to develop computer programs for econometrics, working for much of the time with UK government officials.

In retirement she devoted much of her time to genealogy.

Her (unpublished) memoirs include descriptions of life as a teenager in Portsmouth during the bombing of the Second World War, and of working with early computers at Cambridge.

She is buried at the Parish of the Ascension Burial Ground in Cambridge; in 1997 she completed a remarkable listing of all the graves and their inscriptions in the burial ground; she wrote a paper called "A Walk round the Ascension Burial Ground, Cambridge" which describes over 100 of the graves as though the reader is walking around the burial ground and includes detailed maps. The fourth edition is dated December 1994.

She herself was buried there in 2008, in the same grave as her mother Lucy Dalton Slater (1893 - 1975), widow of John Wardle Slater F.I.C., Admiralty chemist, buried in Portsmouth.
