20th-century psychologists

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.

Hans Bender (5 February 1907 – 7 May 1991) was a German lecturer on the subject of parapsychology, who was also responsible for establishing the parapsychological institute Institut für Grenzgebiete der Psychologie und Psychohygiene in Freiburg. For many years his pipe smoking, contemplative figure was synonymous with German parapsychology. He was an investigator of 'unusual human experience', e.g. poltergeists and clairvoyants. One of his most famous cases was the Rosenheim Poltergeist.
