Hagman's parents divorced in 1936 when he was five years old. He lived with his maternal grandmother, Juanita Presley Martin, in Texas and California while his mother became a contract player with Paramount in 1938. In 1940, Hagman's mother met and married Richard Halliday before giving birth to a daughter, Heller, the following year. Hagman attended a strict academy, Black-Foxe Military Institute. When his mother moved to New York City to resume her Broadway career, Hagman again lived with his grandmother in California. A few years later, his grandmother died and Hagman joined his mother in New York City. In 1946, Hagman moved back to his hometown of Weatherford and attended Weatherford High School. One summer, he worked for oilfield-equipment maker Antelope Tool Company. Although his father wanted Hagman to become a lawyer and join his practice, he was drawn to drama classes and reportedly fell in love with the stage. He graduated from high school in 1949 and decided to pursue acting.
