A Study of Association in Insanity

About the author
Born in Pinsk in the Russian Empire on June 26, 1878, Aaron Joshua Rosanoff later built his career in the United States as a psychiatrist and author of medical texts. He became known for studying psychosis and for writing on mental illness in a way that reached both specialists and students.
Rosanoff is especially associated with Manual of Psychiatry, a book that saw multiple editions and helped introduce psychiatric ideas to generations of readers. His name also appears on research into word association and insanity, showing his interest in how mental disorders might be studied systematically.
At the same time, his life and work are closely linked with the Eugenics Record Office and the Eugenics Research Association. That connection places him in an important, uneasy chapter of medical history: a period when psychiatry, heredity studies, and eugenic thinking were often intertwined. He died on January 7, 1943.
