Margaret Howell Mitchell

Margaret Knox Howell Mitchell (28 October 1901–3 October 1988) was Canada's first internationally recognized ornithologist.
Career highlights.
One of her most notable career achievements was becoming a Secretary at the Royal Ontario Museum in which she worked in the palaeontology department. After Mitchell's position at the Royal Ontario Museum she became a volunteer with the task of helping create and write the "Passenger Pigeon Inquiry" which later became "The Passenger Pigeon in Ontario" (1935). Her volunteer work in ornithology lead to Mitchell to attain the title of the first woman research affiliate in any natural history museum in Canada. She was also a member of the American Ornithologists' Union (AOU) in 1928 and the Wilson Ornithological Society in 1933, although at the time was not allowed to join the all-male birds clubs in the Toronto Area.
