David Wechsler

David Wechsler was a prominent Romanian-American psychologist, born in 1896. His work had a significant impact on the field of psychology, particularly in the development of intelligence scales. Wechsler's most notable contributions include the creation of the Wechsler Adult Intelligence Scale (WAIS) and the Wechsler Intelligence Scale for Children (WISC), which were designed to assess the cognitive abilities of individuals.

Wechsler's intelligence scales were initially developed during his time at Bellevue Hospital, where he utilized these tools to better understand his patients. His work has endured long after his passing in 1981, with his intelligence scales remaining widely used today. A testament to his lasting influence, Wechsler was ranked as the 51st most cited psychologist of the 20th century in a 2002 survey published in A Review of General Psychology, solidifying his position as a leading figure in the field of psychology.
