Roberto Assagioli (27 February 1888 – 23 August 1974) was an Italian psychiatrist and pioneer in the fields of humanistic and transpersonal psychology. Assagioli founded the psychological movement known as psychosynthesis, which is still being developed today by therapists and psychologists who practice the psychological methods and techniques he developed. His work, including two books and many monographs published as pamphlets, emphasized the possibility of progressive integration (that is, synthesis) of the personality.
