Elizabeth MacGill's entire life was defined by "firsts". She was born in Vancouver in 1905 to James MacGill, a respected lawyer, and Helen MacGill, British Columbia's first woman judge. Encouraged by her mother, she decided to study engineering at the University of Toronto, and thus a lifetime of "firsts" began: no woman in Canada had ever graduated with an Electrical Engineering degree until MacGill did in 1927. After earning her degree, she moved to Michigan to work for the Austin Automobile Company, and it was there that her interest in aircraft was sparked. She began pursuing a Master's in Aeronautical Engineering at the University of Michigan, and in 1929 she became the first woman in North America (and probably the world) to earn such a degree.
In the coming years, she had the distinction of being the first ever woman aircraft designer, was put at the head of important aircraft design projects during World War II, was the first woman corporate member elected to the Engineering Institute of Canada, and served as president of the Canadian Federation of Business and Professional Women's Clubs for two years. She also recieved a number of awards during her lifetime, both Canadian and international, including the Order of Canada in 1971. Because of her, women across Canada and the world were inspired to defy boundaries and make their own lives a series of "firsts".
Update: Excitingly, Elizabeth MacGill has made the short-list of women who could end up on Canada's bank notes! and help make sure this incredible pioneer for woman in STEM is recognized for all of her accomplishments.
