Robert Hudson Walker (October 13, 1918 – August 28, 1951) was an American actor, best known for his starring role in Alfred Hitchcock's 1951 thriller Strangers on a Train.
He started in youthful boy-next-door roles, one of them opposite his first wife Jennifer Jones. He also played Jerome Kern in Till the Clouds Roll By. Twice divorced by thirty, he suffered alcoholism and psychiatric disorder, and died during an attempt at medicating his condition.
Born in Salt Lake City, Utah, to Zella (née McQuarrie) and Horace Walker, he was the youngest of four sons. Emotionally scarred by his parents' divorce when he was still a child, he subsequently developed an interest in acting which led his maternal aunt Hortense (McQuarrie) Odlum (the president of Bonwit Teller) to offer to pay for his enrollment at the American Academy of Dramatic Arts in New York City in 1937. Walker lived in her home during his first year in the city.
While attending American Academy of Dramatic Arts, Walker met fellow aspiring actress Phylis Isley, who later took the stage name Jennifer Jones. After a brief courtship, the couple were married in Tulsa, Oklahoma on January 2, 1939 and moved to Hollywood to find work
