The medal and cash prize is awarded once in three years to a woman astronomer anywhere in the world for outstanding contribution to the science. She is considered one of thé foremost authorities on the North American continent on variable stars, and spends 8 to 10 hours a night at the large telescope at the Observatory, the fourth largest in the world.
Dr. Helen Hogg was born in Lowell, Mass. U.S. and studied astronomy at Mount Holyoke College, and later at Redcliffe where she married Dr. Frank Hogg, a fellow astronomer. She is a past president of the American Association of Variable Star Observers, and also a Fellow of the Royal Society of Canada, the only woman in the section devoted to physical sciences.
Dr. Frank Hogg was one of the leading men in his field in Canada, calculating the radial speed at which stars travel to or away from the earth.
He was born in Preston, Ont., graduated from an English University, and took further training at Harvard University, where he met his wife, Dr. Helen Hogg. He was awarded a travelling fellowship, on which he studied a year at Cambridge, and then served as a professor and research worker at Amherst College in Mass. For three years he was astronomer at the Dominion Astro-Physical Observatory in Victoria B.C. In 1935, when the David Dunlop Observatory was Opened, he came to Toronto as associate professor of astronomy at the University. In 1946 he became a full professor, and on the retirement of Dr. R.K. Young became head of the Department and Director of the Observatory. He was also past president of the Royal Astronomical Society of Canada.
