Joseph Leo Mankiewicz (11 February 1909 – 5 February 1993) was an American film director, screenwriter, and producer.
Mankiewicz was born in Wilkes-Barre, Pennsylvania to Franz Mankiewicz (?–1941) and Johanna Blumenau, Jewish immigrants from Germany. He had a sister, Erna Mankiewicz (1901–1979), and a brother, Herman J. Mankiewicz, who became a screenwriter.
At age four, Mankiewicz moved with his family to New York City where he graduated in 1924 from Stuyvesant High School. In 1928, he obtained a bachelor's degree from Columbia University. For a time he worked in Berlin, Germany, as a foreign correspondent for the Chicago Tribune newspaper before being lured into the motion picture business.
