In the 1950s, Eden was a leading British exponent of analytic S-matrix studies in elementary particle physics.
He was subsequently a founding Fellow of Clare Hall, Cambridge in 1966, and from 1987 to 1999 he was vice president of the college.
On the occasion of the 10th anniversary of the founding of Clare Hall, Lord Ashby referred to him as the ‘Father of the Society’.
Malcolm Longair’s Scientific History of the Cavendish Laboratory states ‘there can be no doubt that Eden was ahead of his time in advocating the importance of physics-based interdisciplinary research for the benefit of society.
His students included Michael Boris Green, John Clayton Taylor, Elliot Leader and Geoffrey C. Fox.
