In 1946 Frankl became Executive Director of the Viennese Neurological Health Centre and kept this position until 1971. Frankl married his second wife, Eleonore Schwindt in 1947 and bore a baby daughter, Gabriele. In his post-war career, Frankl received 29 honorary doctorates from universities all over the world. He wrote over 30 books and became the first non-American to be awarded the American Psychiatric Association's prestigious Oskar Pfister Prize and was a visiting professor at Harvard, Stanford and other universities in Pittsburgh, San Diego and Dallas. Frankl has given lectures at 209 universities on five continents. The California International University installed a special chair for Logotherapy - this is the psychotherapeutic school founded by Frankl - often called the “Third Viennese School”, after Freud's Psychoanalysis and Adler's Individual Psychology. The American Medical Society, the American Psychiatric Association and the American Psychological Association have officially recognized Dr. Frankl's Logotherapy as one of the scientifically based schools of psychotherapy.
