Abraham S. Luchins (March 8, 1914 – December 27, 2005) was an American Gestalt psychologist and a pioneer of group psychotherapy.
Luchins was a student and staff member of Max Wertheimer, the main originator of Gestalt psychology.
After Max Wertheimer fled to the US and started lecturing at the New School for Social Research, Luchins worked as his assistant and became one of his closest collaborators from 1936 till 1942.
In the 1970s he and his wife Edith Hirsch published a series of transcripts and reports on Wertheimer's advanced seminars and workshops.
He researched the role of a mental set (Einstellung effect) in the use of the various water jar refill problems.
