Sir Francis Graham-Smith

Abstract Sir Francis Graham-Smith was a towering figure in British astronomy, whose career spanned much of the history of radio astronomy itself. Appointed as the thirteenth Astronomer Royal in 1982 and knighted in 1986, he made foundational contributions to our understanding of radio sources, the interstellar medium, pulsars and the development of radio telescopes. In a multi-faceted career he also made major contributions to science leadership, education, policy and public engagement. As a leader, he established the Isaac Newton Group of telescopes and the Roque de los Muchachos Observatory on La Palma, and his directorship at Jodrell Bank during a critical period ensured the observatory's continued international relevance and scientific excellence. As an educator, he authored numerous textbooks and was a warm mentor to students and junior colleagues. As a policy-former, he served as a pro-vice-chancellor of the University of Manchester and Physical Secretary of the Royal Society. Throughout his long career and retirement, Sir Francis left indelible marks on many people. We will remember his sharp intellect and generosity with time and ideas.
