F. G. Crookshank

Francis Graham Crookshank (1873, Wimbledon – 27 October 1933, Wimpole Street, London) was a British epidemiologist, and a medical and psychological writer, and Fellow of the Royal College of Physicians.

Crookshank was educated at University College London, and trained in medicine at University College Hospital. His work attempted to combine medicine with the individual psychology of Alfred Adler, along with eugenics and the Nietzsche's philosophy of the will.

His 123-page scientific racist publication The Mongol in our Midst (1924) was both popular and controversial in both England and the United States. In 1931, Crookshank published a "greatly enlarged and entirely rewritten" 524-page edition "with numerous illustrations," with responses to critics and additional theories and claims. That work associated the disorder now known as Down syndrome with the admixture of Asian with European "blood".

Crookshank committed suicide in 1933, dying at his house in Wimpole Street, London.
