She was considered a "great scientist and a gracious person" over a career of sixty years. Helen Battles Sawyer Hogg (August 1, 1905 – January 28, 1993) was an American-Canadian astronomer who pioneered research into globular clusters and variable stars. For her first year there, Hogg continued her work photographing globular clusters, amassing thousands of photographs which she used to identify many thousands of variable stars. During the late 1930s, Hogg became one of the first astronomers to travel and work around the world to advance her research, as the globular clusters she was observing were best seen from the southern hemisphere.
