Bob Steele’s career began to take off for good in 1927, when he was hired by production company Film Booking Offices of America (FBO) to star in a series of Westerns. Renamed Bob Steele at FBO, he soon made a name for himself, and in the late 1920s, 1930s and 1940s starred in B-Westerns for almost every minor film studio, including Monogram, Supreme, Tiffany, Syndicate, Republic (including several films of the Three Mesquiteers series) and Producers Releasing Corporation (PRC) (including the initial films of their “Billy the Kid” series), plus he had the occasional role in an A-movie, as in the adaptation of John Steinbeck’s novel, Of Mice and Men in 1939. In the 1940s, Steele’s career as a cowboy hero was on the decline, but he kept himself working by accepting supporting roles in big movies like Howard Hawks’ The Big Sleep, or the John Wayne vehicles Island in the Sky, Rio Bravo and Rio Lobo. Besides these he also made occasional appearances in science fiction films like Atomic Submarine and Giant from the Unknown. Bob Steele also performed on television, including the role of Sergeant Granger in the premiere episode, “The Peacemaker”, in 1957 of the ABC/Warner Brothers western series, Colt .45. In 1957, he was cast as Sam Shoulders in “Bunch Quitter” in another ABC/WB western series, Sugarfoot, with Will Hutchins. He appeared in 1958 and 1959 in two episodes of the NBC western, The Californians, as well as three episodes of Maverick with James Garner, including “The War of the Silver Kings,” “The Seventh Hand,” and “Holiday at Hollow Rock.”

Bob Steele appeared as “Kirby” with Agnes Moorehead and Madlyn Rhue in the 1959 episode “In Memoriam” of another ABC western series, The Rebel, starring Nick Adams. He also appeared as Deputy Sam in four episodes of Hugh O’Brian’s The Life and Legend of Wyatt Earp. In 1959, he appeared with Mason Alan Dinehart, another Wyatt Earp alumnus, in the episode “Half a Loaf” of the syndicated series, Death Valley Days, hosted by Stanley Andrews. Bob Steele appeared in six different episodes of the Walt Disney’s Western television series Texas John Slaughter with Tom Tryon. On January 25, 1960, Steele was cast as the frontier gunfighter Luke Short in an episode of the CBS western series, The Texan, starring Rory Calhoun. Barbara Stuart played the gambler Poker Alice in the same episode, which also features Reed Hadley and Richard Devon. In the middle 1960s, Steele was cast in a regular supporting role as Trooper Duffy in ABC’s F Troop, which allowed him to show his comic talent. Trooper Duffy in the F Troop story line claimed to have been “shoulder to shoulder with Davy Crockett at the Alamo” and to have been the only survivor of the battle forty years before. In real life, forty years before F Troop, Steele played a supporting role in his father’s 1926 film Davy Crockett at the Fall of the Alamo. Bob Steele died on December 21, 1988 from emphysema after a long illness. He was survived by his third wife of forty-nine years, Bertha Virginia Nash Tatum Steele (1914–1992). Steele is interred in the columbarium at Forest Lawn Memorial Park in the Hollywood Hills.
