[1] She helped design three different machines including the ARC (Automatic Relay Calculator), SEC (Simple Electronic Computer), and APE(X)C. Kathleen Britten was born in Stourbridge, Worcestershire, England,[2] on 9 July 1922.
[7] While at Princeton, she co-authored "General Considerations in the Design of an All Purpose Electronic Digital Computer," [8][9] describing modifications to the original ARC redesign to the ARC2 using a von Neumann architecture.
[13] Booth regularly published papers concerning her work on the ARC and APE(X)C systems and co-wrote "Automatic Digital Calculators" (1953) which illustrated the 'Planning and Coding' programming style.
[14] In 1957, she, her husband, and J.C. Jennings co-founded Birkbeck College's Department of Numerical Automation,[15] now the School of Computer Science and Information Systems, in 1957.
[6] 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.
