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 Nietzsche's philosophy of the will. Crookshank committed suicide in 1933, dying at his house in Wimpole Street, Westminster.
