Following a period of U.S. government service in Bolivia and military service in Germany, he returned to MIT in 1946 as an Assistant Professor of Mineral Engineering. Mr. Spedden was the recipient of an honorary professional degree of Mineral Dressing Engineer from Montana School of Mines in 1964.

Leaving his academic position in 1952, he joined the Metals Research Laboratories of Union Carbide, Niagara Falls, where he was Manager of the Minerals and Chemical Engineering Group until he was assigned to Union Carbide's New York headquarters as Director of Research for its Ore Division in 1957. He transferred to his present position with Kennecott in 1964.
