Her daughter the engineer

"Elsie MacGill, the world's first female aeronautical engineer and professional aircraft designer, influenced early bush planes and guided production of famous aircraft in World War II. 'Elsie the engineer' was also the driving force on Canada's Royal Commission on the Status of Women and every inch the daughter of the suffragette judge Helen MacGill. Affected by muscle paralysis at 24, Elsie often struggled to walk as she pursued her amazing career."--Provided by publisher.
