Thaddeus Eugene Weckowicz (c. 1919 – July 29, 2000) was a Polish-Canadian social scientist, Professor Emeritus of Psychiatry, Psychology, and Theoretical Psychology at the University of Alberta, and Research Associate, Center for Systems Research, University of Alberta,[1] known for his research in chronic schizophrenics since the 1950s.
[3] He received his Bachelor of Medicine (MB and ChB) from the Polish School of Medicine at the University of Edinburgh, his Diploma in Psychological Medicine (DPM) from the University of Leeds and his PhD from the University of Saskatchewan in Saskatoon, Saskatchewan, Canada.
[6] he "undertook perceptual experiments with patients in a long, narrow room that we built for him and established that schizophrenia does distort perception of distance, leaving a victim unsure about the space in which he moves".
From 1962 to 1984 Weckowicz was Professor of Psychiatry and Psychology at the University of Alberta, and Research Associate, Center for Systems Research, University of Alberta.
Weckowicz was married to Helen Pauline Grit Liebel-Weckowicz, Professor of History and Classics at the University of Alberta from 1962 to 1995, with whom Weckowicz co-authored the 1990 book A History of Great Ideas in Abnormal Psychology and some other articles.
