Benjamin Franklin McGrath, known as Frank McGrath (February 2, 1903 – May 13, 1967), was an American television and film actor and stunt performer who played the comical, optimistic cook with the white beard, Charlie B. Wooster, on the western series Wagon Train for five seasons on NBC and then three seasons on ABC. McGrath appeared in all 272 episodes in the eight seasons of the series, which had ended its run only two years before his death. McGrath's Wooster character hence provided the meals and companionship for both fictional trail masters, Ward Bond as Seth Adams and John McIntire as Christopher "Chris" Hale.
McGrath died at the age of sixty-four of a heart attack in Beverly Hills, California. He is interred at Forest Lawn Memorial Park in Glendale, California. His widow, the former Libby Quay Buschlen (1902-1978), a native of Ontario, Canada, was the daughter of George and Caroline Andrews Buschlen. Libby McGrath outlived her second husband by eleven years. She had a son, Quay Casey Dillon (1924-2006), from her marriage to George Vernon Cassey (1896-1949), a native of Kansas who served in World War I and is interred at the Los Angeles National Cemetery. Libby McGrath is interred by neither husband but at Valhalla Memorial Park Cemetery in North Hollywood, California.
McGrath was the second cast member of Wagon Train to die. Ward Bond died early in November 1960. Other Wagon Train co-stars who have since died are Terry Wilson, John McIntire, Robert Horton, and Denny Scott Miller. Still living are former Wagon Train co-stars Robert Fuller and Michael Burns.
In the fall of 1968, CBS resurrected McGrath's Charlie Wooster character for the western series, Lancer, starring Andrew Duggan as a ranch owner. The Wooster-style role was taken by Paul Brinegar, formerly the Wishbone character on Rawhide, who then played a cantankerous cook named Jelly Hoskins.
