Fifth Presentation of the James B. Macelwane Award, April 20, 1966
Don Anderson was born in Frederick, Maryland, thirty-three years ago. He took his Bachelor's degree at Rennselaer Polytechnic Institute in 1955. Between 1955 and 1958 he worked for Chevron Oil Company, served in the Air Force, and conducted research for the Arctic Institute of North America. He...
