Verena Winifred Holmes (23 June 1889 – 20 February 1964) was an English mechanical engineer and multi-field inventor, the first woman member elected to the Institution of Mechanical Engineers (1924), and a strong supporter of women in engineering. She was one of the early members of the Women's Engineering Society, and its president in 1931. She was the first practising engineer to serve as president of the society.
She was born at Highworth, Ashford, Kent to Florence Mary Holmes (née Syme) (d. 1927), and Edmond Gore Alexander Holmes, chief inspector of elementary schools for England. She was one of three children, her brother Maurice Gerald Holmes (1885–1964) became a leading British civil servant.
She took night classes at the Shoreditch Technical Institute and attended a technical college in Lincoln; she served as an apprentice form-fitter and drafter before graduation from Loughborough Engineering College in 1922 with a BSc(Eng) degree.
Her technical specialities included marine and locomotive engines, diesel and internal combustion engines. She became an associate member of the Institution of Marine Engineers in 1924 and was admitted to the Institution of Locomotive Engineers in 1931.
She was employed by Research Engineers Ltd. from 1932–39, during which time she developed and patented many inventions, including the Holmes and Wingfield pneumo-thorax apparatus for treating patients with tuberculosis, a surgeon's headlamp, a poppet valve for steam locomotives, and rotary valves for internal combustion engines. She held patents for 12 inventions for medical devices as well as engine components.
During World War II she worked on naval weaponry and in 1940 became adviser to Ernest Bevin, the minister of labour, on the training of munition workers. She was appointed headquarters technical officer with the Ministry of Labour (1940-1944). She was heavily involved in encouraging and supporting women in engineering. Together with Caroline Haslett and Claudia Parsons, she was active in the Women's Engineering Society founded in 1919. She served that society in several capacities, including president in 1930 and 1931.
Support for women's engineering
Her work in support of women in engineering was based partly upon her own experiences; although she had been admitted to the Institution of Mechanical Engineers as an associate member in 1924, it took twenty years for her to be admitted as a full member. She founded the engineering firm of Holmes and Leather in 1946, which employed only women. Using a design created by Holmes, this firm created the first practical safety guillotine for paper, making it suitable for introduction into schools. In 1958, she published a booklet, Training and Opportunities for Women in Engineering.
From 1969, the Women's Engineering Society supported a yearly Verena Holmes lecture, given at various venues across Britain to children aged nine to eleven to encourage interest in engineering,  although now the programme is closed. Verena Holmes' birthday of 23 June coincides with International Women in Engineering Day and she is commemorated as part of that celebration.
