Gregory Bateson
Upon completion of military service in 1960, he accepted a position as a research associate with Leonard Krasner at the Palo Alto Veterans Administration Hospital, working on a grant focused on the operant conditioning of verbal behavior in psychiatric patients. Ekman also met anthropologist Gregory Bateson in 1960 who was on the staff of the Palo Alto Veterans Administration Hospital. Five years later, Gregory Bateson gave Paul Ekman motion picture films taken in Bali in the mid-1930s to help Ekman with cross-cultural studies of expression and gesture.
