The correspondence and papers of Thomas Gold, astrophysicist, 1920-2004. The papers that comprise this collection provide a fascinating insight into Thomas Gold's research, views and life as an academic. They relate to almost very aspect of his career from his work at the Admiralty Signal Establishment, research into the theory of hearing and controversy over his proposal that the surface of the moon would be covered with a layer of fine-grained rock powder, to his advocacy of the contentious theory that oil and gas deposits are non-biological (abiogenic) in origin and his proposal, proved correct, that microbial life exists deep beneath the earth's surface.
