John Patrick Mahon, a director, writer and actor known for his roles in “L.A. Confidential” and “Zodiac,” died of natural causes in his home in Los Angeles, Calif., on May 3. He was 82.

Born in Scranton, Pa., Mahon attended the University of Scranton where he studied classical languages and English literature. In 1950, he contracted poliomyelitis and never recovered full motor function of his left arm, spending much of his career in entertainment paralyzed by the infection.

Mahon is survived by his two children, Katharine Elizabeth Ann and Joseph Patrick Mahon.
