Professor Kathleen Booth, one of the last of the early British computing pioneers, has died. She was 100.
Kathleen Hylda Valerie Britten was born in Worcestershire, England, on July 9, 1922. During the Second World War, she studied at Royal Holloway, University of London, where she got a BSc in mathematics in 1944. After graduating, she became a junior scientific officer at the Royal Aircraft Establishment, a research organization in Farnborough. Two years later she moved to Birkbeck College, first as a research assistant, and later a lecturer and then research fellow.
She also worked at the British Rubber Producers’ Research Association (BRPRA), where she met and worked with mathematician and physicist Andrew Donald Booth, who later became her husband. After studying with X-ray crystallographer Professor J D Bernal – inventor of the Bernal Sphere – A D Booth was working out crystal structures using X-ray diffraction data, and finding the manual calculations very tedious; he built an analog computer to automate part of this.
