We are very sorry to have to announce the death of Honorary Fellow Professor Sir Tony Leggett, who died at the age of 87. 

Tony’s time as a student in Oxford began with an undergraduate degree in Classics at Balliol College and ended with a DPhil in Physics supervised by Professor Dirk ter Haar, a Fellow of Magdalen. 

Tony was subsequently elected to a Fellowship by Examination at Magdalen College in 1963, followed by a Fellowship in Physics in 1965, and Honorary Fellowship in 2006. 

In 1967, Tony took up a lectureship at the University of Sussex, where he was to spend the majority of the next fifteen years of his career.

During the mid-1970s, Tony spent considerable time in Japan at the University of Tokyo and also at Kwame Nkrumah University of Science and Technology in Kumasi, Ghana. 

In 1983, Tony was elected the John D. and Catherine T. MacArthur Professor and Centre for Advanced Study Professor of Physics at the University of Illinois Urbana-Champaign.

Tony was widely recognised as a world leader in the theory of low-temperature physics, and his pioneering work on superfluidity earned him the 2003 Nobel Prize in Physics.
