Charles Dawson "Daws" Butler (November 16, 1916 – May 18, 1988) was a voice actor originally from Toledo, Ohio. He worked mostly for Hanna-Barbera and originated the voices of many familiar animated cartoon characters, including Yogi Bear, Quick Draw McGraw, Snagglepuss, and Huckleberry Hound.

Daws Butler was born on November 16, 1916 in Toledo, Ohio, the only child of Ruth Butler and Charles Allen Butler. The family later moved from Ohio to Oak Park, Chicago, where Butler got interested in impersonating people.

In 1934, the future voice master started as an impressionist, entering multiple amateur contests and winning most of them. He had entered them, not with the intention of showing his talent but as a personal challenge to overcome his shyness, with success. Nonetheless, Butler won professional engagements at vaudeville theaters. Later he teamed up with fellow performers, Jack Lavin and Willard Ovitz to form the comedy trio The Three Short Waves. The team played in theaters, radio and nightclubs, generating positive reviews from regional critics and audiences. They dissolved when in 1941, Daws Butler joined the U.S. Navy as America entered World War Two. Some time after, he met his wife Myrtis during a wartime function at North Carolina.

Stanley Victor "Stan" Freberg (born August 7, 1926) is an American author, recording artist, animation voice actor, comedian, radio personality, puppeteer and advertising creative director, whose career began in 1944. He is still active in the industry in his mid-80s, nearly 70 years after entering it.

Born in Pasadena, California, Freberg is the son of a Baptist minister. His work reflects both his gentle sensitivity (despite his liberal use of biting satire and parody) and his refusal to accept alcohol and tobacco manufacturers as sponsors—an impediment to his radio career when he took over for Jack Benny on CBS radio. As Freberg explained to Rusty Pipes:

Stan Freberg's first wife, Donna, died in 2000. He has two children from that marriage, Donna Jean and Donavan. He married Betty Hunter in 2001, and she adopted the personal and family names Hunter Freberg.

Freberg was employed as a voice actor in animation shortly after graduating from Alhambra High School. He began at Warner Brothers in 1944 by getting on a bus and asking the driver to let him off "in Hollywood." As he describes in his autobiography, It Only Hurts When I Laugh, he did this, getting off the bus and finding a sign that said "talent agency." He walked in, and the agents there arranged for him to audition for Warner Brothers cartoons where he was promptly hired.

James Gilmore "Jim" Backus (February 25, 1913 – July 3, 1989) was an American radio, television, film, and voice actor. Among his most famous roles are the voice of nearsighted cartoon character Mr. Magoo, the rich Hubert Updike III on the radio version of The Alan Young Show, Joan Davis's character's husband (a domestic court judge) on TV's I Married Joan, James Dean's character's father in Rebel Without a Cause and Thurston Howell, III on the 1960s sitcom Gilligan's Island. He also starred in his own show of one season, The Jim Backus Show, also known as Hot off the Wire.

An avid golfer, Backus made the 36-hole cut at the 1964 Bing Crosby Pro-Am tournament.

James Gilmore Backus was born February 25, 1913 in Cleveland, Ohio, and raised in Bratenahl, Ohio, a wealthy village surrounded by greater Cleveland. He was the son of Russell Gould Backus, a mechanical engineer, and Daisy Gilmore (née Taylor) Backus. Backus was expelled from the Kentucky Military Institute for riding a horse through the mess hall.^{[citation needed]}

Sandra Gould (July 23, 1916 – July 20, 1999) was an American actress, who appeared mainly in television. Among her many credits was a regular role on the sitcom Bewitched as the second Gladys Kravitz.

Gould began acting in films with an uncredited role in T-Men (1947). She appeared in several uncredited roles for the remainder of the decade, and received her first screen credit with The Story of Molly X (1949). During the same decade, Gould enjoyed a four-year run as Miss Duffy, the man-hungry daughter of the forever-unheard owner of radio's Duffy's Tavern.In 1953, Gould appeared as a guest in an episode of Letter to Loretta with Loretta Young.

She continued to guest star in the 1950s and 1960s in such television series as I Love Lucy, December Bride, Maverick, The Flintstones, The Twilight Zone, The Lucy Show, Burke's Law, I Dream of Jeannie, Love, American Style, Gilligan's Island and Mister Ed. She played a prominent supporting role in the film The Ghost and Mr. Chicken in 1966. In 1963, Gould released a comedy single record entitled Hello Melvin (This Is Mama) as an answer to Allan Sherman's hit "Hello Muddah, Hello Fadduh".

Donald Earl "Don" Messick (September 7, 1926 – October 24, 1997) was an American voice actor best known for his work for Hanna-Barbera. His best remembered vocal creations include Scooby-Doo, Muttley the dog in Wacky Races and Dastardly and Muttley in Their Flying Machines', Papa Smurf, and Dr. Benton Quest. He also did the voice of "Snip" in the Rankin/Bass 1979 movie "Jack Frost".

Messick was born in Buffalo, New York, the son of Lena Birch (née Hughes) and Binford Earl Messick, a house painter. He first wanted to be a ventriloquist, and even supported himself as one for a time. His big break came in the mid-1940s. At MGM, Tex Avery was producing the Droopy cartoons. The regular voice actor, radio actor Bill Thompson, was not available. Daws Butler, who voiced characters for MGM, suggested that Avery seek out Messick, and so, he was hired to voice Droopy. Later, in the mid-1950s, when Bill Thompson parted company with MGM, Messick took over the role of Droopy.

Messick and Butler became a voice acting team for the Hanna-Barbera unit in 1957 with the arrival of Ruff and Reddy. Don was Ruff the cat and the Droopy-sounding Professor Gizmo. Butler was the southern-speaking dog, Reddy. Messick also narrated the show, which played out like an animated soap opera.
