Helen Battles Sawyer Hogg (August 1, 1905 – January 28, 1993) 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 ("With the Stars", 1951–81) and the Journal of the Royal Astronomical Society of Canada ("Out of Old Books", 1946–65). She was considered a "great scientist and a gracious person" over a career of sixty years.
