Gaston Vandendriessche (28 November 1924[1] – 14 October 2002) was a Belgian psychologist, best known for his extensive study on the so-called Haizmann case, first analyzed by Sigmund Freud in 1923.
Vandendriessche was born in Roeselare. He studied psychology at the University of Leuven and published his doctoral thesis, Het Haizmann-geval van Sigmund Freud: Onderzoek betreffende het grondmateriaalen de psychologische interpretaties, in 1962, and continued to research and write on the Haizmann case until the 1990s in Dutch, French, German and English language.
His best-known work is probably the book The Parapraxis in the Haizmann Case of Sigmund Freud from 1965. According to H. C. Erik Midelfort, this book is a “devastating demolition of Freud’s interpretation” but he also thinks that Vandendriessche is “careful and respectful”[2] in his argumentation.
Vandendriessche served as a professor of psychology at the University of Leuven. He died in 2002 in Leuven, aged 77.
