James Arthur "Jim" Krumhansl (August 2, 1919 – May 6, 2004) was an American physicist who specialized in condensed matter physics and materials science. He spent much of his career at Cornell University. He also served as president of the American Physical Society and assistant director for mathematics, physical sciences, and engineering for the National Science Foundation. In 1987 he testified before Congress that the Superconducting Super Collider would be too costly.
Krumhansl was born August 2, 1919, in Cleveland, Ohio. He married twice; each marriage ended in divorce. He had three children: Carol L. Krumhansl, James L. Krumhansl, and Peter A. Krumhansl.
Krumhansl did his undergraduate work in electrical engineering at the University of Dayton, earning a B.S. in 1939. He went on to receive an M.S. from Case Western Reserve University in 1940 and a Ph.D. from Cornell University in 1943. Both graduate degrees were in physics. His doctoral dissertation concerns the klystron.
After earning his Ph.D. Krumhansl spent one year as an Instructor in Physics at Cornell. In 1944 he left Cornell for the Stromberg-Carlson Company, where he researched microwave pulse communication systems for the U.S. Navy during World War II. He remained at Stromberg-Carlson until 1946, when he became an assistant professor of physics and applied mathematics at Brown University. He was promoted to associate professor in 1947. In 1948 he moved back to Cornell as an assistant professor of physics and was promoted to associate professor in 1950. In 1955 he returned to industry as a research director for the National Carbon Company.
