Heinrich Klüver

Heinrich Klüver (/ˈkluːvər/; May 25, 1897 – February 8, 1979) was a German–American psychologist born in Holstein.

After having served in the Imperial Germany Army during World War I, he studied at both the University of Hamburg and the University of Berlin from 1920-23. In the latter year, he arrived in the United States to attend Stanford University. He received his Ph.D. in physiological psychology from Stanford University. In 1927 he married Cessa Feyerabend and settled in the United States permanently, becoming a naturalized U.S. citizen in 1934. Klüver was a member of the 'core group' of cybernetics pioneers that participated in the Macy Conferences of the 1940s and 1950s. He collaborated most often and fruitfully with Paul Bucy and made various contributions to neuroanatomy throughout his career.

His expositions of and experiments with mescaline were also groundbreaking at the time. He coined the term "cobweb figure" in the 1920s to describe one of the four form constant geometric visual hallucinations experienced in the early stage of a mescaline trip: "Colored threads running together in a revolving center, the whole similar to a cobweb". The other three are the chessboard design, tunnel, and spiral. Klüver wrote that "many 'atypical' visions are upon close inspection nothing but variations of these form-constants."[1]
