General semantics has survived most profoundly in the cognitive therapies that emerged in the 1950s and 1960s. Albert Ellis (1913–2007), who developed rational emotive behavior therapy, acknowledged influence from general semantics and delivered the Alfred Korzybski Memorial Lecture in 1991. The Bruges (Belgium) center for solution-focused brief therapy operates under the name Korzybski Institute Training and Research Center. George Kelly, creator of personal construct psychology, was influenced by general semantics. Fritz Perls and Paul Goodman, founders of Gestalt therapy are said to have been influenced by Korzybski Wendell Johnson wrote "People in Quandaries: The Semantics of Personal Adjustment" in 1946, which stands as the first attempt to form a therapy from general semantics.
