Ken Curtis (July 2, 1916 – April 28, 1991) was an American singer and actor best known for his role as Festus Haggen on the long-running CBS western television series Gunsmoke.

Though born as Curtis Wain Gates in Lamar in Prowers County in southeastern Colorado, Curtis was reared west of there in Las Animas, the seat of Bent County. His father, Dan Gates, was the Bent County sheriff. The family lived above the jail and his mother, Nellie Sneed Gates, cooked for the prisoners. The jail is now located for historical preservation purposes on the grounds of the Bent County courthouse in Las Animas.

Curtis played quarterback for his high school football team.

Curtis was a singer before moving into acting and combined both careers once he entered films, performing with the popular Sons of the Pioneers from 1949 to 1953 as well as singing with the Tommy Dorsey band. Curtis replaced Frank Sinatra as vocalist for the Dorsey band. He was with the Dorsey band in 1941, prior to Sinatra's departure, and may have served simply as insurance against Sinatra's likely defection. Dick Haymes contractually replaced Sinatra, in 1942. Curtis then joined Shep Fields and His New Music, an all-reeds band that dispensed with a brass section.

Milburn Stone (July 5, 1904 – June 12, 1980) was an American television actor, a nephew of Broadway comedian Fred Stone and the son of a shopkeeper, best known for his role as "Doc" (Dr. Galen Adams) on the CBS western series Gunsmoke. He also played a doctor, CDR Blake, in the 1943 film Gung Ho!.

Stone was born in Burrton in Harvey County in central Kansas. He began his screen career in the 1930s, having been featured in Monogram Pictures' series of "Tailspin Tommy" adventures. In 1940, he appeared with Marjorie Reynolds, Tristram Coffin, and I. Stanford Jolley in the comedy espionage film Chasing Trouble. He also played the liberal minded warden in Monogram Pictures', "Prison Mutiny", in 1943. Stone was signed by Universal Pictures in 1943 and became a familiar face in its features and serials. One of his film roles was a radio columnist in the Gloria Jean-Kirby Grant musical I'll Remember April. He made such an impression in this film that Universal gave him a starring role (and a similar characterization) in the 1945 serial The Master Key.

Shep Fields (September 12, 1910 – February 23, 1981) was the band leader for the "Shep Fields and His Rippling Rhythm" orchestra during the Big Band era of the 1930s.

He was born Saul Feldman in Brooklyn, New York on September 12, 1910, and his mother's maiden name was Sowalski. Edward Fields, a carpet manufacturer; and Freddie Fields were his brothers. Their father died at the age of 39.

He played the clarinet and tenor sax in bands during college. In 1931 he played at the Roseland Ballroom. By 1933 he led a band that played at Grossinger's Catskill Resort Hotel. In 1934 he replaced the Jack Denny Orchestra at the Hotel Pierre in New York City. He left the Hotel Pierre to join a roadshow with the dancers, Veloz and Yolanda. In 1936 he was booked at Chicago's Palmer House, and the concert was broadcast on radio.

Fields was at a soda fountain when his wife was blowing bubbles into her soda through a straw, and that sound became his trademark that opened each of his shows. A contest was held in Chicago for fans to suggest a new name for the Fields band, in keeping with the new sound. The word "rippling" was suggested in more than one entry, and Fields came up with "Rippling Rhythm."

Louis Burton Lindley, Jr. (June 29, 1919 – December 8, 1983), better known by the stage name Slim Pickens, was an American rodeo performer and film and television actor who epitomized the profane, tough, sardonic cowboy, but who is best remembered for his comic roles, notably in Dr. Strangelove and Blazing Saddles.

Pickens was born Louis Burton Lindley, Jr. in Kingsburg, California, the son of Sally Mosher (née Turk) and Louis Bert Lindley, Sr. He was an excellent rider from age 4 and quit school to join the rodeo at 12. He was told that working in the rodeo would be "slim pickings" (very little money), giving him his name, but he did well and eventually became a well-known rodeo clown.

After 20 years on the rodeo circuit, his distinctive Oklahoma-Texas drawl (even though he was a lifelong Californian), his wide eyes and moon face and strong physical presence gained him a role in the western Rocky Mountain (1950) starring Errol Flynn. He appeared in many more westerns, playing both villains and comic sidekicks to the likes of Rex Allen.

Amanda Blake (February 20, 1929 – August 16, 1989) was an American actress best known for the role of the red-haired saloon proprietress "Miss Kitty Russell" on the television western Gunsmoke.

Born Beverly Louise Neill in Buffalo, New York, she was a telephone operator before taking up acting.

Nicknamed "the Young Greer Garson," she became best known for her 19-year stint as the saloon-keeper Miss Kitty on the television series Gunsmoke from 1955 until 1974. In 1968, Blake was inducted into the Hall of Great Western Performers at the National Cowboy & Western Heritage Museum in Oklahoma City. She was the third performer inducted, after Tom Mix and Gary Cooper, who were selected in 1958 and 1966 respectively.

Because of her continuing role on television, Blake rarely had time for films. She appeared in a TV comedy routine with Red Skelton and was a panelist on the long-running Hollywood Squares and Match Game 74. In 1957, she guest-starred as Betty Lavon-Coate in the episode of "Coate of Many Colors" on Rod Cameron's syndicated series western-themed crime drama, State Trooper.
