Questionnaire with brief, typed responses, in which Kopal refers often to his published memoir, Of Stars and Men: Reminiscences of an Astronomer (UK: Adam Hilger, 1986). Recipients were asked to discuss their decision to enter astronomy; their work during the Second World War; their professional work outside astronomy; the fields in which they have been most active, the advances in both those fields and others, and their own accomplishments and satisfactions; sources of funding; their perceptions of public attitudes; the influence of religion or philosoophy on their work as astronomers; and their opinions on questions relating to the Big Bang Theory, cosmology, up-coming important developments, and the search for extraterrestrial intelligence.
