Phyllis Nicolson

Nicolson was born Phyllis Lockett in Macclesfield and went to Stockport High School for Girls. She graduated from Manchester University with a B.Sc. in 1938, M.Sc. in 1939 and a Ph.D. on Three Problems in Theoretical Physics in 1946. ==Hartree Differential Analyser work==

Nicolson's Ph.D. was expected to be submitted in 1941 but was interrupted by wartime work with Douglas Hartree's research group at Manchester University from 1940 to 1945. During this time, Nicolson became a proficient numerical analyst and an expert user of Hartree's differential analyser. Nicolson, along with other members of the research group worked on defence-related problems for the Air Defence Research and Development Establishment (later the Radar Research and Development Establishment), both part of the Ministry of Supply. Nicolson's two significant bodies of wartime research, "Transient behaviour in the single anode magnetron" and "heat conduction", formed the basis of parts II and III of her 1946 PhD thesis Three Problems in Theoretical Physics. ==Postwar life and work==

Nicolson was a research student in Cambridge from 1945 and completed her Ph.D. thesis completed at the Victoria University of Manchester (now Manchester University) in 1946. Nicolson moved to Leeds around January 1950 with her husband Malcolm Nicolson, also a physicist, as he had been appointed to a lectureship in Physics at Leeds University. and geology. Nicolson died from breast cancer in 1968 in Sheffield. ==Publications==
