Carlson was born in Ironwood, Michigan and earned bachelor's (1930), master's (1932) and Ph.D. (1938) degrees from the University of Michigan. Carlson participated in the University of Michigan Greenland Expedition of 1928–1929 and led the fourth University of Michigan Greenland Expedition in 1930–1931. After completing his education, he joined the University of Minnesota as an assistant professor of education, eventually becoming a full professor and dean of admissions and records.

He served in the Air Force during the Second World War, building air bases in Canada, Greenland, and Iceland for transport to Britain.

After the war, he assumed the presidencies of the University of Delaware, the University of Vermont, and the State University of New York in rapid succession. He undertook his longest Presidency at the University of Toledo, from which he retired after 14 years.

Carlson succumbed to lung cancer in Belleair Bluffs, Florida. The main library on the University of Toledo campus is named after him.
