This series consists of the general files that Mr. Grenville assembled in his attempt to write Dr. Solandt’s story. It begins with a variety of biographical information on Dr. Solandt, including curriculum vitae, tributes and obituaries, his memorial service, press clippings, and an article about him. This is followed by grant applications, a project outline, correspondence, and files on sources, family history, and Dr. Solandt’s activities (including summaries of diaries), arranged alphabetically. The principal areas of activity covered are the atomic bomb/nuclear weapons, Canadian National Railway, Defence Research Board, forestry, medical research, operational research, the Science Council of Canada, and ‘voyaguers’. The photographs associated with some of the files have been removed and stored separately.
