Elizabeth "Betty" Audrey Killick (10 September 1924 – 7 July 2019) FREng was a British naval electronics engineer who worked on radar and weapons systems for the Ministry of Defence.

[1] Her maternal grandfather was a political agent, and her mother's brothers worked for the London Stock Exchange.

[2][1] When she was demobilized in 1947, Killick was briefly at the Royal Air Force Institute of Aviation Medicine as a laboratory assistant, before going to the University of St Andrews where she earned a degree in natural philosophy in 1951 and was awarded an honorary doctorate in 1998.

[1] By 1966 she had risen to the civil service grade of Senior Principal Scientific Officer – and was the first woman to achieve this rank[1] – although the ASRE had by then been absorbed into the Admiralty Surface Weapons Establishment (ASWE).

[2][4][1] She served as a board member for the Marine Technology Directorate, where she coordinated projects between the government, academia and industry.

[1] Killick was described as "a brilliant, if somewhat volatile, engineer who was both terrifying and inspiring to her colleagues" but who was at the same time "a formidable authority" with a strong sense of humour.
