Born on this date (Jun. 24) in 1915, the maverick English astrophysicist and cosmologist Fred Hoyle, who did important work in nucleosynthesis and championed the steady-state theory of the universe. Educated in mathematics and theoretical physics at Cambridge University, he returned there after wartime work on radar development and remained from 1945 to 1973, with many long-term visits to the California Institute of Technology and the Mount Wilson and Palomar Observatories. He was appointed Plumian Professor of Astronomy and Experimental Philosophy in 1958 and founded Cambridge's Institute of Theoretical Astronomy and served as its first director. His early work on stellar evolution led to his famous collaboration with Margaret and Geoffrey Burbidge and William Fowler on the synthesis of the elements beyond helium in stars. Hoyle successfully predicted the existence of a resonance in carbon-12 that was essential to helium burning in stars. In 1948 Hoyle, Hermann Bondi, and Thomas Gold developed the steady-state cosmological model. Hoyle provided a mathematical theory of the model consistent with the general theory of relativity and served as the leading spokesman for the new theory, coining the term “Big Bang” for the competing model during a radio lecture.
Hoyle was an early supporter of the modern view that extrasolar planets and life are ubiquitous. In his standard text Frontiers of Astronomy (1955) he wrote:
“[W]e may expect planetary systems to have developed around the majority of stars.... Living creatures must it seems be rather common.”
Hoyle allowed his fertile imagination full rein in his science fiction novels, such as The Black Cloud (1957), in which an intelligent interstellar cloud arrives in the solar system, and A for Andromeda and its sequel, in which he turned to some of the possible consequences of SETI.
