Correspondence about Thomas Gold's appointments at Cornell University and Harvard University, 1956-1957 Contains correspondence between Thomas Gold and various individuals, such as McGeorge Bundy, Donald H Menzel, Director, Harvard College Observatory, Arthur Kantrowitz, E E Salpeter and Harry Plaskett, Nov-Dec 1955, Jan-Sep 1956. The correspondence relates to Thomas Gold working at Cornell University during the first semester of the 1956-1957 academic year and his appointment as Professor of Astronomy at Harvard University. It also relates to his move to America in general e.g. obtaining a visa to go to America, finding a house to rent for himself and his family during his time at Cornell University. According to the correspondence, Gold resigned from his position as Chief Assistant to the Royal Astronomer at the Royal Greenwich Observatory with the intention of spending just a year in America (the plan being for him to spend one semester at Cornell University and another at Harvard University) and then returning to England to take up a position as a Senior Research Officer at the University Observatory, Oxford. However, Harvard University offered him a permanent full professorship (which he took up in February 1957). Nov 1955-Sep 1956
