Earlier today I heard the sad news of the death at the age of 85 of astronomer Roger Griffin. He passed away on 12th February 2021.

Roger Griffin worked at Cambridge for over six decades, except for one year when he had a post-doctorate position at the Mount Wilson and Palomar Observatories, of the Carnegie Institution of Washington. He was the Assistant Director of Research in Astronomy at the University of Cambridge for nine years before he was promoted to a Readership of Observational Astronomy and later a Professorship. He appeared in the film Starmen alongside Donald Lyndon-Bell, Wal Sargent and Neville “Nick” Woolf.

Roger Griffin worked on astronomical spectroscopy and his main scientific claim to fame was that he invented a method of measuring radial velocities of stars in binary systems described in this classic paper published in 1967:

Over the subsequent years he published many radial velocity curves thus obtained in a long series of papers in the Observatory Magazine and the same method was subsequently used for measuring orbits of black holes and detecting extrasolar planets.

Despite the Cambridge connection I never met Roger Griffin personally but people who did talk about him with great affection and he will be greatly missed.

Rest in peace, Roger Griffin (1935-2021)
