- 1911 – Anna Terruwe, Dutch psychiatrist and author (d. 2004).
Dr. Anna A. A. Terruwe (19 August 1911 to 28 April 2004, Deurne) was a Catholic psychiatrist from the Netherlands. She discovered emotional deprivation disorder and how obsessive-compulsive disorder could be healed: the “bevestigingsleer,” the idea of “affirmation.”
Terruwe based her work on that of Thomas Aquinas and “the relevance of Thomistic rational psychology to neurosis and its treatment.” Her work is also based on that of Professor W.J.A.J. Duynstee, C.SS.R., LL.D. who studied Aquinas. Her theories are based on Aquinas’ understanding of what he calls the “nature of man.”
