Research Scientist at British Rubber Producers' Research Association and for ten years from 1952 to 1962 she was Research Fellow and Lecturer at Birkbeck College, University of London. Booth's research on neural networks led to successful programs simulating ways in which animals recognise patterns and characters. She and her husband resigned suddenly from Birkbeck College in 1961 after a chair was not conferred on her husband despite his massive contributions; an ICT 1400 computer was donated to the Department of Numerical Automation but was in fact installed in the London School of Hygiene and Tropical Medicine. In 1962, after leaving Birkbeck College the Booth family moved to Canada to where she became a Research Fellow, Lecturer and Associate Professor at the University of Saskatchewan until 1972. At Lakehead University in Canada she became the Professor of Mathematics from 1972 to 1978. Kathleen Booth retired from Lakehead in 1978. Her last current paper was published in 1993 at the age of 71. Titled "Using neural nets to identify marine mammals" it was co-authored by Dr. Ian J. M. Booth, her son. Personal life and death She died on 29 September 2022, at the age of 100. Bibliography . . Booth A.D. and Britten K.H.V.
