Herbert Fröhlich

Personal life Fröhlich was born on 9 December 1905 in Rexingen, Baden-Württemberg. He was the son of Fanny Frida (née Schwarz) and Jakob Julius Fröhlich, members of an old-established Jewish family, and the brother of Albrecht Fröhlich, a mathematician who was elected Fellow of the Royal Society in 1976.

Career In 1927, Fröhlich entered Ludwig-Maximilians-Universität München (LMU Munich) to study physics, and received his doctorate under Arnold Sommerfeld in 1930.

In 1950, Bell Telephone Laboratories offered Fröhlich their endowed professorial position at Princeton University. However, at Liverpool he had a purely research post which was attractive to him. He was then newly married to an American, Fanchon Angst, who was studying linguistic philosophy at Somerville College, Oxford under P. F. Strawson, and who did not want to return to the United States at that time.

From 1973, he was Professor of Solid State Physics at the University of Salford, however, all the while maintaining an office at the University of Liverpool, where he gained emeritus status in 1976 and remained there until his death. During 1981, he was a visiting professor at Purdue University. He was nominated for the Nobel Prize in Physics in 1963 and in 1964.

Fröhlich, who pursued theoretical research notably in the fields of superconductivity and bioelectrodynamics, proposed a theory of coherent excitations in biological systems known as Fröhlich coherence. A system that attains this coherent state is known as a Fröhlich condensate, similar to room-temperature non-equilibrium Bose–Einstein condensation of quasiparticles.

Honours and awards Fröhlich was elected a Fellow of the Royal Society (FRS) in 1951. In 1969, he received an honorary DSc from Trinity College Dublin.
