J. Robert Kantor was born on 8 August 1888 in Harrisburg, Pennsylvania, to Russian immigrants. His first interest in science was in chemistry at the University of Chicago, but an introduction to psychology changed his focus. He earned a PhB in 1914 and a PhD in psychology in 1917 from the University of Chicago. His dissertation, “Functional Nature of the Philosophical Categories,” examined the history of philosophy and explored how this historical analysis can aid psychology to overcome the prevailing model of psychology as the study of simple reflexes.
