A tough but great Professor for whom I had great respect.

Bro. Don was my major professor while I worked to complete my MS in Biology (1969-1971). He is the reason I became a biologist, initially thinking that I would teach Biology, but then ultimately switching to being a research biologist. Beside the science that I learned from Don, I learned a number of life lessons as well, not the least of which is to have confidence and trust my own knowledge and skillset. He was a true mentor and friend, and he will be missed.
