Elizabeth Muriel Gregory MacGill (March 27, 1905 – November 4, 1980), known as the "Queen of the Hurricanes", was a Canadian engineer. She was chief aeronautical engineer at Canadian Car and Foundry (CC&F) in Fort William, Ontario during the Second World War. There she oversaw manufacturing of 1,451 Hawker Hurricane fighter aircraft for the Royal Canadian Air Force and the British Royal Air Force, then 835 Curtiss Helldivers for the U.S. Navy, which contributed greatly to the war effort and did much to make Canada a powerhouse of aircraft manufacturing. After her work at CC&F, she ran a successful aeronautical engineering consulting business. Between 1967 and 1970, she was a commissioner on the Royal Commission on the Status of Women in Canada, which published a report in 1970.
MacGill was born in Vancouver on March 27, 1905, youngest daughter of James Henry MacGill, a prominent Vancouver lawyer, part-time journalist, and Anglican deacon, and Helen Gregory MacGill, a journalist and British Columbia's first woman judge. She had two older stepbrothers from her mother's first marriage, and an older sister with whom she was very close.
In the early years, the MacGill children were home-schooled in a formal setting to mimic that of Lord Roberts, the public school that the older boys attended. This included drawing lessons with Emily Carr, and swimming lessons with Joe Fortes. They later attended King George Secondary School, which was affiliated with McGill University. This rigorous education facilitated Elsie's entrance to the University of British Columbia when she was 16. She was admitted to the Applied Sciences program, but the Dean of the Faculty asked her to leave after only one term.
When MacGill was 12 years old, her mother was appointed judge of the juvenile court of Vancouver. After 1911, racial strife in British Columbia continued to escalate, and Jim MacGill's immigration-related legal work was directly impacted. This caused severe financial strain for the family during the war years. Her early aptitude for "fixing things" stood the family in good stead, and informed discussions of possible careers.
MacGill's mother was an advocate of women's suffrage and influenced Elsie's decision to study engineering.
My presence in the University of Toronto's engineering classes in 1923 certainly turned a few heads.
Although I never learned to fly myself, I accompanied the pilots on all test flights – even the dangerous first flight – of any aircraft I worked on.
MacGill was admitted to the University of Toronto's Bachelor of Applied Sciences program in 1923. During the summers she worked in machine shops repairing electrical motors to supplement the theory and practical teachings during the school year. It is also here that she became exposed to the nascent field of aeronautical engineering. Contracting polio just before her graduation, MacGill was told that she would probably spend the rest of her life in a wheelchair. She refused to accept that possibility though, and learned to walk supported by two metal canes. Elsie graduated from the University of Toronto in 1927, the first Canadian woman to earn a degree in electrical engineering.
After graduating, MacGill took a junior job with Austin Aircraft Company in Pontiac, Michigan, which furthered her interest in aeronautics. She also began part-time graduate studies in aeronautical engineering at the University of Michigan, enrolling in the fall of 1927 in the full-time Master of Science in Engineering program to begin aircraft design work and conduct research and development in the university's new aeronautics facilities. In 1929, she became the first woman in North America, and perhaps the world, to be awarded a master's degree in aeronautical engineering.
She pursued PhD studies at MIT in Cambridge from 1932–34. In order to help finance her doctoral studies, MacGill wrote magazine articles about aircraft and flying. Her contemporary at MIT was aeronautical engineer and technical writer, M. Elsa Gardner.
In 1934, MacGill started work at Fairchild Aircraft's operations in Longueuil as an assistant aeronautical engineer. She contributed to various aviation projects including the Fairchild Super 71 (the first aircraft designed and built in Canada featuring a metal fuselage), the Fairchild 82 (a bush plane), and the Fairchild Sekani (twin-engined transport aircraft). She presented a paper, "Simplified Performance Calculations for Aeroplanes", to the Royal Aeronautical Society in Ottawa, on March 22, 1938, to high praise. It was later published in The Engineering Journal. She also participated in the Canadian Broadcasting Corporation's six-part series, The Engineer in War Time; her segment was called "Aircraft Engineering in Wartime Canada". In 1942, she was elected to the position of chairman of the EIC, Lakehead Branch, after having also served as their vice-chairman.
Later that year MacGill was hired as Chief Aeronautical Engineer at Canadian Car and Foundry (CanCar). There she designed and tested a new training aircraft, the Maple Leaf Trainer II.
The Maple Leaf Trainer was designed and first built in CanCar's Fort William (now Thunder Bay) factories, where MacGill had moved. Although the Maple Leaf II did not enter service with any Commonwealth forces, ten (two were completed, but eight had to be assembled in Mexico) were sold to Mexico where its high-altitude performance was important, given the many airfields from which it had to operate. Her role in the company changed when the factory was selected to build the Hawker Hurricane fighter aircraft for the Royal Air Force (RAF). The factory had to be quickly expanded from about 500 workers to 4,500 by war's end, half of them women. McGill was responsible for tooling up production for more than 25,000 precision parts; the parts had to be interchangeable with Hurricanes manufactured in the U.K. For much of the war MacGill's primary task was to set up and streamline operations in the production line as the factories rapidly expanded. This involved designing and adapting machine tools to enable quantity manufacturing to exacting specifications. She was also responsible for designing solutions to allow the aircraft to operate during the winter, introducing de-icing controls and a system for fitting skis for landing on snow.
By the time the production line shut down in 1943, CanCar had produced 1,451 Hurricanes. In 1940 she wrote and presented a paper on the experience, "Factors Affecting Mass Production of Aeroplanes", later published in The Engineering Journal . Her role in this successful production run made her famous, to the point of having a comic book biography appear in an issue of True Comics in 1942, using her nickname, "Queen of the Hurricanes”. Numerous popular stories were published about her in the media as well, reflecting the public's fascination with this woman engineer.
After Hurricane production ended, CanCar looked for new work and secured a contract from the United States Navy to build Curtiss SB2C Helldivers. Again MacGill was responsible for all engineering and production work, and the plant ultimately produced 835 aircraft, significantly contributing to Allied air power. This production did not go nearly as smoothly, and a continual stream of minor changes from Curtiss-Wright (in turn demanded by the U.S. Navy) meant that full-scale production took a long time to get started.
MacGill moved to Toronto, where she set up an aeronautical engineering consulting business with Bill Soulsby in 1943. In 1946, she became a Technical Adviser for International Civil Aviation Organization (ICAO), where she helped to draft International Air Worthiness regulations for the design and production of commercial aircraft. In 1947 she became the chairman of the United Nations Stress Analysis Committee, the first woman ever to chair a U.N. committee.
In 1952, MacGill presented a paper to the Society of Women Engineers (SWE) conference, "The Initiative in Airliner Design", that was subsequently published in The Engineering Journal. A year later SWE awarded her their annual Achievement Award.
