Lucy Joan Slater (5 January 1922 – 6 June 2008) was a mathematician who worked on hypergeometric functions, and who found many generalizations of the Rogers–Ramanujan identities.
Slater was interested in jazz music and played the piano as an accompanist in her early years.
and Ph.D. from London University while studying hypergeometric equations, including her publication of a list of over 100 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.
Her (unpublished) memoirs include descriptions of life as a teenager in Portsmouth during the bombing of the Second World War, and of working with early computers at Cambridge.
