A native of Germany, he came to this country as a teenager and served in the Army from 1943 to 1946. In 1949 he graduated from Rensselaer Polytechnic Institute and in 1952 Princeton awarded him a Ph.D. in chemistry.

From 1952 until he retired in 1984, Frensdorff worked for DuPont in various research capacities. He published 20 papers in scientific journals and was awarded two patents. From 1977 through 1980, he was the editor of Rubber Chemistry and Technology, the official journal of the rubber division of the American Chemical Society. After retiring from DuPont, he was the editor of the Journal of Macromolecular Science – Chemistry from 1985 to 1989.
