American-Canadian astronomer and academic (died 1993)

Helen Sawyer Hogg

Helen Battles Sawyer Hogg was an American-Canadian astronomer who pioneered research into globular clusters and variable stars. She was the first female president of several astronomical organizations and a scientist when many universities would not award scientific degrees to women. Her dedication to sharing astronomy with the wider public led to scientific advocacy and journalism, including columns in the Toronto Star and the Journal of the Royal Astronomical Society of Canada. She was considered a "great scientist and a gracious person" over a career of sixty years.
