Martin Sam Milner (born December 30, 1931) is an American actor best known for his performances in two popular television series, Adam-12 and Route 66. He has also appeared in other television series, numerous films, radio dramas, a Broadway play, and even a radio fishing show. In addition, his appearance was the inspiration for Guy Gardner, the Green Lantern Corps superhero created in 1969 by John Broome and Gil Kane. Milner was born to film distributor Sam Gordon Milner and Paramount Theater circuit dancer Mildred E. "Jerre" Martin in Detroit, Michigan. The family left Detroit when he was very young, and moved frequently before settling in Seattle by the time he was nine. It was in Seattle that he became involved in acting, first in school, and then in a children's theater group at the Cornish Playhouse. When Milner was fourteen, he moved with his family to Los Angeles where his parents hired an acting coach and later an agent for the budding star. Milner had his first screen test and began his film career with his debut in the 1947 film Life With Father, in the role of "John Day," the second oldest son of "Clarence Day" played by William Powell.
