Bernd Theodor Matthias (June 8, 1918 – October 27, 1980) was a German-born American physicist credited with discoveries of hundreds of elements and alloys with superconducting properties. He was said to have discovered more elements and compounds with superconducting properties than any other scientist.
Matthias was born in Frankfurt, Germany on June 8, 1918. He received his PhD in physics from the Federal Institute of Technology in Zurich in 1943. He immigrated to the United States in 1947 and went to work for Bell Laboratories.
He taught at the Massachusetts Institute of Technology and the University of Chicago before joining the physics faculty of University of California, San Diego in 1961. He remained at UCSD for the rest of his career, conducting research and mentoring students who became distinguished physicists in their turn. He is best known for his work on solid state physics and the behavior of matter at extremely low temperatures; he also did important work on ferroelectricity. Matthias was also a member of the JASON defense advisory group.
In 1965 he was elected to both the National Academy of Sciences and the American Academy of Arts and Sciences.
He received the Oliver E. Buckley Condensed Matter Prize in 1970 and James C. McGroddy Prize for New Materials in 1979.
The University of California, San Diego has an endowed chair in physics named for him; the Bernd T. Matthias Chair in Physics is currently held by M. Brian Maple, who received his PhD under Mathias.
