Fred Hoyle
Sir Fred Hoyle (24 June 1915 – 20 August 2001) was an English astronomer. With Margaret and Geoffrey Burbidge and William Alfred Fowler, he formulated the theory of stellar nucleosynthesis in the influential B2FH paper.
He held controversial views on some scientific matters — in particular, in his rejection of the "Big Bang" theory (a term he jokingly coined on BBC Radio, though he later denied doing so in derision) in favour of a "steady-state model", and his promotion of panspermia as the origin of life on Earth.
He spent most of his working life at St John's College, Cambridge, and served as the founding director of the Institute of Theoretical Astronomy at Cambridge.
Hoyle also wrote science fiction novels, short stories, and radio plays, co-created television serials, and co-authored twelve books with his son, Geoffrey Hoyle.
Hoyle was born near Bingley in Gilstead, West Riding of Yorkshire, England. His father Ben Hoyle was a violinist and worked in the wool trade in Bradford, and served as a machine gunner in the First World War. His mother, Mabel Pickard, had studied music at the Royal College of Music in London and later worked as a cinema pianist. Hoyle was educated at Bingley Grammar School and read mathematics at Emmanuel College, Cambridge. As a youth, he sang in the choir at the local Anglican church.
In 1936, Hoyle shared the Mayhew Prize with George Stanley Rushbrooke.
In late 1940, Hoyle left Cambridge to go to Portsmouth to work for the Admiralty on radar research, for example devising a method to get the altitude of incoming aeroplanes. He was also put in charge of countermeasures against the radar-guided guns found on the Graf Spee after its scuttling in the River Plate. Britain's radar project was a large-scale operation, and was probably the inspiration for the large British project in Hoyle's novel The Black Cloud. Two colleagues in this war work were Hermann Bondi and Thomas Gold, and the three had many discussions on cosmology. The radar work involved several trips to North America, where he took the opportunity to visit astronomers. On one trip to the US, he learned about supernovae at Caltech and Mount Palomar and, in Canada, the nuclear physics of plutonium implosion and explosion, noticed some similarity between the two and started thinking about supernova nucleosynthesis. He had an intuition at the time "I will make a name for myself if this works out" (he published his prescient and groundbreaking paper in 1954). He also formed a group at Cambridge exploring stellar nucleosynthesis in ordinary stars and was bothered by the paucity of stellar carbon production in existing models. He noticed that one existing process would be made a billion times more productive if the carbon-12 nucleus had a resonance at 7.7 MeV, but nuclear physicists at the time omitted such an observed value. On another trip, he visited the nuclear physics group at Caltech, spent a few months of sabbatical there and persuaded them against their scepticism to find the Hoyle state in carbon-12, from which a full theory of stellar nucleosynthesis was developed, co-authored by Hoyle and members of the Caltech group.
In 1945, after the war ended, Hoyle returned to Cambridge University as a lecturer at St John's College, Cambridge (where he had been a Fellow since 1939). Hoyle's Cambridge years, 1945–1973, saw him rise to the top of world astrophysics theory, on the basis of a startling originality of ideas covering a wide range of topics. In 1958, Hoyle was appointed Plumian Professor of Astronomy and Experimental Philosophy in Cambridge University. In 1967, he became the founding director of the Institute of Theoretical Astronomy (subsequently renamed the Institute of Astronomy, Cambridge), where his innovative leadership quickly led to this institution becoming one of the premier groups in the world for theoretical astrophysics. In 1971, he was invited to deliver the MacMillan Memorial Lecture to the Institution of Engineers and Shipbuilders in Scotland. He chose the subject "Astronomical Instruments and their Construction". Hoyle was knighted in the 1972 New Year Honours.
