Sir Samuel Frederick Edwards

FLSW (1 February 1928 – 7 May 2015) was a Welsh physicist.[1][2]
The
Sam Edwards Medal and Prize is named in his honour.[3]

Early life and studies

Edwards was born on 1 February 1928 in Swansea, Wales, the son of Richard and Mary Jane Edwards. He was educated at the Bishop Gore School, Swansea, and Gonville and Caius College, Cambridge, the University of Manchester, and at Harvard University, in the United States.[2] He wrote his thesis under Julian Schwinger on the structure of the electron, and subsequently developed the functional integral form of field theory.

Academic research

Edwards's name on Staircase L at Gonville & Caius College, Cambridge in 2010.

Edwards's work in condensed matter physics started in 1958 with a paper[pubs 1] which showed that statistical properties of disordered systems (glasses, gels etc.) could be described by the Feynman diagram and path integral methods invented in quantum field theory. During the following 35 years Edwards worked in the theoretical study of complex materials, such as polymers, gels, colloids and similar systems. His seminal paper[pubs 2] came in 1965 which "in one stroke founded the modern quantitative understanding of polymer matter."[1] Pierre-Gilles de Gennes notably extended Edwards's 1965 seminal work, ultimately leading to de Gennes's 1991 Nobel Prize in Physics.[1]

Edwards invented what is known as the

amorphous solids. His seminal 1971 paper[4] was the first paper to introduce the replica trick and Edwards' seminal work led ultimately to Giorgio Parisi's 2021 Nobel Prize in Physics
.

The Doi-Edwards theory of polymer melt viscoelasticity originated from an initial publication of Edwards in 1967,[pubs 3] was expanded upon by de Gennes in 1971, and was subsequently formalized through a series of publications between Edwards and Masao Doi in the late 1970s.[1]

Administrative activities and professional recognition

He was Chairman of the Science Research Council 1973-1977 and between 1984 and 1995 was

Cambridge University. He was a member of the Board of Sponsors of The Bulletin of the Atomic Scientists
and Past President of Cambridge Society for the Application of Research.

Edwards was knighted in 1975. Awards presented to him include the

Boltzmann medal of the International Union of Pure and Applied Physics (1995),[6] and the Dirac Medal of the International Centre for Theoretical Physics (2005). He was also a Founding Fellow of the Learned Society of Wales
and he held an honorary degree (Doctor of Science) from the University of Bath (1978).

Personal life

In 1953 Edwards married Merriell E.M. Bland, with whom he had three daughters and a son. His relaxations were gardening and chamber music. Edwards died in Cambridge on 7 May 2015.[1][7]

Professor Sam Edwards, who recently became chairman of the Science Research Council, describes himself as someone who has always had a taste for difficult problems. Recently, he talked to Martin Sherwood about some of the problems he has tackled in chemistry and physics, and some of those he will now have to tackle as a full-time administrator.
