Morris R Cohen was born probably on Jul 25,1880, and spent his first years in a Jewish ghetto in Minsk, Russia. He early displayed a preference for the contemplative life. His education was that of an Orthodox Jew. In 1892 the family emigrated to New York, where, during the next 7 years, Cohen drifted away from organized religion and eventually gave up all belief in a personal God. Ever since he had shared a room with Felix Frankfurter at Harvard, Cohen had indulged a lively interest in jurisprudence, which resulted in, amongst others, "Reason and Studies in Juristic Philosophy". When Cohen died on Jan 28,1947, he left many works half finished which his son, Felix, a scholar in his own right, published.
