Gertrude Lilian Entwisle (12 June 1892 – 18 November 1961) was an electrical engineer. She was the first British woman to retire from a complete career in industry as a professional engineer; the first female engineer to work at British Westinghouse; and the first female student, graduate, and associate member of the Institution of Electrical Engineers (now the Institution of Engineering and Technology).[2][3] Entwisle was known for her work on designing DC motors and exciters. She was in her Journal of the Institution of Electrical Engineers obituary as "[breaking] through many barriers of prejudice to become a respected designer of electrical rotating machinery."[2]

Early life and education[edit]

Entwisle was educated at Manchester High School for Girls and obtained a scholarship to the University of Manchester where she studied from 1911 to 1914. Entwisle originally studied physics including under Ernest Rutherford, but was able to attend engineering classes when they were opened to female students.[1][2] In July 1914, Entwisle failed her preliminary physics examination and left the University of Manchester without graduating.[1]

Early Career during World War I[edit]

In 1915, at the beginning of the World War I, British Westinghouse (later Metropolitan-Vickers) was looking into the recruitment of women engineers to manage the shortages of skilled technical employees at the time.[4] The Chief Engineer John S Peck (who had taken out patents on electrical distribution systems[5]) had approached the Manchester College of Science and Technology to enquire about suitable candidates, and when the invitation came to Entwisle's attention she joined the company, working first on test results and then on the design of DC motors.[6] There was some consternation among the management when she asked for permission to enter the engineering works: eventually it was decided that she was permitted as long as she did not wear trousers.[7] During World War I, Entwisle spent her weekends nursing in a Red Cross hospital and also attended evening classes at Manchester College of Science and Technology.[1]

Later career[edit]

Being an umarried woman, Entwisle was able to continue working at British Westinghouse after the war's end as they did not hire married women. She spent most of her career working on the design, manufacturing, and cost of AC and DC machines, in particular DC motors.[1] Towards the end of her career, Entwisle concentrated on exciters, on which she became something of a specialist.

On 20 June 1954, Entwisle retired from Metropolitan-Vickers after an uninterrupted professional career of thirty-nine years as an electrical design engineer.[1] She was the first British woman to retire from a complete career in industry as a professional engineer.[2]

Professional organisations[edit]

Entwisle joined the Institution of Electrical Engineers as a Student Member in 1916 and became a Graduate Member in 1919 and an Associate Member in 1920 - she was the first woman to become a member in each of these grades.[3] When she attended her first IEE lecture, the chairman of the meeting stopped proceedings as he suspected her of being a militant suffragette bent on disrupting the meeting. She was, however, soon accepted by her fellow engineers, and the next time she was barred from a meeting the secretary appeared to vouch for her.[7]

The Women's Engineering Society (WES) had been founded in 1919, and Entwisle was one of its founder members. She was a member of Council, first secretary of the Manchester Branch and President from 1941-1943.[8] Entwisle retired from the WES council in 1954, the year of her professional retirement.

Entwisle also had a significant involvement with the Electrical Association of Women (EAW), founded in 1924 and a "daughter organisation" of the Women's Engineering Society.[1] She was a member of its national executive committee during the society's early years and the first honorary secretary of the EAW's Manchester branch, formed in 1926. Entwisle also belonged to the British Federation of University Women and of the Association of Scientific Workers trade union. She was also the first female member of the Society of Technical Engineers.[9]
