Michael Landon

Landon was born Eugene Maurice Orowitz on October 31, 1936, in Forest Hills, a neighborhood of Queens, New York. His parents were Kathleen "Peggy" (née O'Neill; a dancer and comedian) and Eli Maurice Orowitz. His father was Jewish, and his mother was Roman Catholic. Eugene was the Orowitz family's second child; their daughter, Evelyn, was born three years earlier, in 1933. In 1941, when Landon was 4, he and his family moved to the borough of Collingswood, New Jersey. He attended, and celebrated his bar mitzvah at Temple Beth Sholom. His family recalls that Landon "went through a lot of hassle studying for the big event, which included bicycling to a nearby town every day in order to learn how to read Hebrew and recite prayers."

During his childhood, Landon was constantly worrying about his mother attempting suicide. He reported that on a family beach vacation, his mother tried to drown herself, but Landon rescued her. Shortly after the attempt, his mother acted as if nothing happened, and a few minutes later, he vomited. He said that it was the worst experience of his life. Stress overload from the suicide attempts of his mother caused Landon to battle the childhood problem of bedwetting, which was reported in the unauthorized biography Michael Landon: His Triumph and Tragedy. His mother put his wet sheets on display outside his window for all to see. He ran home every day and tried to remove them before his classmates could see. Some of these experiences were incorporated into his semi-autobiographical television movie, The Loneliest Runner, which he wrote, produced and directed.

Landon attended Collingswood High School and was an excellent javelin thrower, with his 193 ft 4 in (58.93 m) toss in 1954 being the longest throw by a high schooler in the United States that year. This earned him an athletic scholarship to the University of Southern California, but he subsequently tore his shoulder ligaments, putting an end to his days as a college athlete and as a student. Landon considered show business and served as an attendant at a service gas station opposite the studios of Warner Bros. He was eventually noticed by Bob Raison, a local agent. Following advice, Landon changed his surname, selecting a new one from a phone book.
