Sir Robert Lewis Fullarton Boyd (19 October 1922 – 5 February 2004) was a pioneer of British space science and founding director of the Mullard Space Science Laboratory (part of University College London).
His scientific career started at the Admiralty Mining Establishment in 1943 where he worked with some notable scientists, including Francis Crick, Thomas Gaskell and Harrie Massey.
Boyd succeeded Harrie Massey as the chair of the British National Committee for Space Research in 1976.
He became a Fellow of the Royal Society in 1969, was awarded its Bakerian Medal in 1978, and was knighted in 1983 in recognition of his services to space science.
Boyd was a committed Christian and he saw no conflict but subtle complementarity between science and religion.
