He directed the Tales of the Texas Ranger radio series from 1950 to 1952, which made the transition to TV, also created, produced and directed by Stacy Keach, Sr.

Keach appeared in a 1955 episode of The Lone Ranger. Keach also appeared as Sheriff Ben Mason in the 1957 episode "Last Chance" of the ABC/Warner Brothers western television series, Colt .45.

That same year, he was cast as Jed Hammer in the episode "Trail's End" of the ABC/WB western series, Sugarfoot, starring Will Hutchins. Keach was cast in 1957 and 1958 in five episodes of the NBC western series, The Californians.

Keach is probably best known for his role as Carlson in the NBC sitcom, Get Smart. In 1965 he appeared on Perry Mason in the role of the trial court judge in "The Case of the Cheating Chancellor."

Keach was born in Chicago, Illinois. He was of English descent. His career ranged from 1942 to 1997, with more than seventy movie and television appearances.

Keach's lookalike son, Stacy Keach, Jr., enjoys an acting career with far greater name recognition than his father's. The younger Keach is perhaps best known for starring in the title role of the Mike Hammer television series in the 1980s and 1990s. Another son, James Keach, an actor, director, and producer, was married to the actress Jane Seymour.

Keach, Sr., died of congestive heart failure at the age of eighty-eight in Burbank, California.
