Peter Pauson

Peter Ludwig Israel Pauson FRSE FRIC (1925–2013) was a German–Jewish emigrant who settled in Britain and who is remembered for his contributions to chemistry, most notably the Pauson–Khand reaction and as joint discoverer of ferrocene.

Life

He was born in Bamberg, Germany on 30 July 1925, the son of Stefan Pauson and his wife, Helene Dorothea Herzfelder. His parents escaped to England in 1939 with Peter and his two sisters to flee the Nazi persecution of Jews.

In 1942 the family moved to Glasgow and he began studying chemistry in the University of Glasgow under Thomas Stevens Stevens. After graduating in 1946, he moved to Sheffield University as a postgraduate, studying under Robert Downs Haworth and receiving his doctorate in 1949. He then went to Duquesne University in Pittsburgh, Pennsylvania and pursued research on tropolones and other aromatic non-benzenoid molecules. His discovery of ferrocene with his student, Thomas J. Kealy, arose from an attempt to dimerize cyclopentadienylmagnesium bromide using Iron(III) chloride; the orange-yellow solid with formula C10H10Fe was described as a "molecular sandwich" in Pauson's note which was published in Nature in 1951.

Pauson and his postdoctoral assistant, Ihsan Khand, discovered the reaction now renowned as the Pauson–Khand reaction in 1971, though Pauson always referred to it as the "Khand reaction".

Pauson retired in 1995 and died peacefully at home on 10 December 2013. He was cremated at Clydebank Crematorium. In his obituary, he is described as "a gentleman of modesty, humility, and compassion … a fine man and a marvellous scientist". having met her at a party hosted by Enrico Fermi when Pauson was at the University of Chicago in the early 1950s. They went on to have two children, Hilary and Alfred.
