After the war, he got a degree from Oberlin College. He worked in New York for several years, working his way up from copy boy to reporter for the New York Sun, and then working for the New York Daily News, and worked there for two years. In the 1950s he moved to Miami to pursue writing full-time. He started writing the Two-Minute Mysteries series in 1959, and he started writing his popular Encyclopedia Brown mystery series for children in 1963.
