Timothy Francis Leary, Jr. (1920-1996), a psychologist and writer, became known as an advocate for the use of psychedelic drugs and a counterculture icon. David Clarence McClelland (1917-1998) was an American psychologist, noted for his work on motivation Need Theory. McClelland published a number of works during the 1950s and the 1990s and developed new scoring systems for the Thematic Apperception Test (TAT) and its descendants. The majority of the collection (1959-1962) consists of letters written to David and Mary McClelland during the period Leary was living in Denmark with his family. He discusses his work; personal life and family; his travels; and arrangements for moving back to America and working at Harvard University. There are also two undated reports on the effects of psilocybin written by subjects.
