Fifteen Fellows of the Royal Society and three Nobel Laureates (Chandrasekhar, Dirac, and Mott) were supervised by Fowler between 1922 and 1939. In addition to Milne, he worked with Sir Arthur Eddington, Subrahmanyan Chandrasekhar, Paul Dirac and Sir William McCrea. It was Fowler who introduced Dirac to quantum theory in 1923. Fowler also put Dirac and Werner Heisenberg in touch with each other through Niels Bohr. At Cambridge he supervised the doctoral studies of 64 students, including John Lennard-Jones, Paul Dirac and Garrett Birkhoff. The Fowler Islands, in Crystal Sound, on the Antarctic Peninsula were named by the UK Antarctic Place-Names Committee in his honour. Personal life Fowler was a keen amateur cricketer who played as a wicket-keeper. He played for Norfolk in the Minor Counties Championship in 1908 and 1909.

Eileen died after the birth of their last child, Ruth Fowler Edwards, a geneticist and wife of Robert G. (Bob) Edwards, the "father" of in vitro fertilization and 2010 Nobel Prize in Physiology or Medicine laureate. One of his grandchildren is Mary Fowler, a geophysicist and the sixth Master (2012–2020) of Darwin College, Cambridge. Selected publications with E. A.
