   Helen Sawyer’s husband got a job at an observatory in Victoria, BC. Officially, she worked there as his "volunteer assistant."

   It was there that she began her work on variable stars in clusters. The detailed catalogs that she started compiling during this period (and first published in 1939) are still in use today.
