Thesis title: ``Problems in the classical and quantum theories of gravitation’’ (Salam bet with Bondi) First postdoc at ICTP Trieste 1972-73 Faculty colleague at Imperial College 1979-88 Two kinds of genius? Salam was a ``magician’’ Abdus Salam Chair of Theoretical Physics, Imperial College, 2006-2015

13. © Imperial College LondonPage 13 Salam: a cultural amphibian A man of two worlds: ``Salam has the heart of a poet and the mind of a scientist. He is an excellent physicist concerned with deep patterns; he is also a deeply compassionate man. These two threads intertwined throughout his life’’ Robert Walgate, New Scientist, 1976
