Canada lost one of its most famous and best-loved astronomers with the death of Professor Helen B. Sawyer Hogg in Richmond Hill, Ontario on January 28, 1993. She was a life-long variable star observer who served as President of the AAVSO from 1939 to 1941, and maintained a keen interest in the Association throughout her life.
