Two different head and shoulders images of Dr. Don Gray, Division of Hydrology, Agricultural Engineering.

Bio/Historical Note: Dr. Donald M. Gray was born on 27 October 1929 in Princeton, British Columbia, where he completed his schooling and was very active in athletics, notably skiing and baseball. He continued his education at the University of Guelph where he obtained his MA and then completed his PhD in Agricultural Engineering at the University of Iowa. In 1960 he accepted a position at the University of Saskatchewan. There was little formalized hydrology study in Canada until Dr. Gray provided "Familiarization Seminars on the Principles in Hydrology" in 1967. Notes for this course eventually led to the publication of the Handbook on the Principles of Hydrology (1970) and his subsequent book, Handbook of Snow: Principles, Processes, Management and Use (1981, 2004) which is recognized globally as the key technical book on snow and, in either the original issue or translation, is the core textbook for snow hydrology and engineering courses at universities around the world. Dr. Gray had a distinguished career as a professor of Agricultural and Bioresource Engineering, the Chairman of the Division of Hydrology and as Assistant Dean of Research and Extension, College of Engineering at the University of Saskatchewan. Dr. Gray was considered to be one of the world's leading scientists in the fields of snow hydrology and prairie hydrology. He was instrumental in the establishment of the National Hydrology Research Center in Saskatoon in the 1980s and was the chair of a committee of Deans who recommended that the University form a Research Corporation. Innovation Place is now one of the most advanced and successful research parks in North America. In recognition of Dr. Gray’s many accomplishments, he was awarded the J. Tuzo Wilson Award in 2000 by the Canadian Geophysical Union. Dr. Gray died on 20 January 2005 in Saskatoon.
