Robert M. Lindner (May 14, 1914 – February 27, 1956) was an American author and psychologist, best known as the author of the 1944 book Rebel Without A Cause: The Hypnoanalysis Of A Criminal Psychopath,[1] from which the title of Nicholas Ray's 1955 film was adapted. His book described a psychopath as someone who is "incapable of exertions for the sake of others".[2] Lindner's arguments on gambling psychology are well regarded and have been noted as "definitive statements" by the American Academy of Political and Social Science.[3]
