# Wally Cox
**Wally Cox** (Wallace Maynard Cox, December 6, 1924 – February 15, 1973) was an American actor and comedian best known for playing the shy science teacher Robinson J. Peepers on the live NBC sitcom *Mister Peepers* (1952–1955) and for voicing the title character of the animated series *[Underdog](https://www.edgepedia.org/underdog-tv-series)*.[1](https://www.imdb.com/name/nm0185281/bio/) • [2](https://www.worldradiohistory.com/BOOKSHELF-ARH/History/Total-Television-Programming-1948-1991-McNeil.pdf) His television persona, a timid man in horn-rimmed glasses with a soft, precisely enunciated voice, was one his lifelong friend [Marlon Brando](https://www.edgepedia.org/marlon-brando) said was completely at odds with the real man.[1](https://www.imdb.com/name/nm0185281/bio/)

## Early life and nightclub career
Cox was born in Detroit and moved as a child to [Evanston, Illinois](https://www.edgepedia.org/evanston-illinois), where he met the young Marlon Brando at school; the two became lifelong friends and later roommates in New York City.[1](https://www.imdb.com/name/nm0185281/bio/) • [3](https://www.latimes.com/local/obituaries/la-me-wally-cox-19730216-story.html) The family moved frequently, and Cox graduated from Denby High School in Detroit.[9](https://doyletatum.com/2025/10/22/wally-cox/) During World War II he attended [City College of New York](https://www.edgepedia.org/city-college-of-new-york), served about four months in the [United States Army](https://www.edgepedia.org/united-states-army), and then studied at New York University.[9](https://doyletatum.com/2025/10/22/wally-cox/) • [7](https://walkoffame.com/wally-cox/)
**From silversmith to stand-up.** Supporting his invalid mother and sister, Cox made and sold jewelry in a small shop and at parties, where he began performing comedy monologues.[7](https://walkoffame.com/wally-cox/) These characterizations, offbeat stories of a boyhood pal and imitations of an Army drill sergeant rather than joke-telling, led to regular nightclub work, beginning with a December 1948 debut at the Village Vanguard in [Greenwich Village](https://www.edgepedia.org/greenwich-village).[10](https://www.allmusic.com/artist/wally-cox-mn0000814216) • [11](https://www.tvinsider.com/people/wally-cox/) Brando encouraged him to study acting with [Stella Adler](https://www.edgepedia.org/stella-adler).[1](https://www.imdb.com/name/nm0185281/bio/) In early 1950 Cox appeared in the Broadway musical revue *Dance Me A Song*, winning raves even though the show itself received lukewarm reviews, and he went on to appear on radio and television shows headlined by [Perry Como](https://www.edgepedia.org/perry-como), Ed Sullivan, Garry Moore, and Arthur Godfrey.[11](https://www.tvinsider.com/people/wally-cox/)
## Mister Peepers
In 1952 producer Fred Coe and writer David Swift created *Mister Peepers* for Cox after NBC liked the audience response to his appearance in a Swift comedy on the *Goodyear TV Playhouse*; as Swift recalled, "What could you do for Wally Cox? You write Mr. Peepers. It's the only thing he could do."[12](https://www.worldradiohistory.com/BOOKSHELF-ARH/History/Storytellers-to-the-Natioin-Stempel1992.pdf) The half-hour series, broadcast live from New York, starred Cox as Robinson J. Peepers, a mild-mannered science teacher at Jefferson Junior High, and was introduced in July 1952 as a summer replacement for *Ford Theater*.[2](https://www.worldradiohistory.com/BOOKSHELF-ARH/History/Total-Television-Programming-1948-1991-McNeil.pdf) When the fall replacement series *Doc Corkle* failed after three episodes, NBC brought *Mister Peepers* back with a new sponsor, Reynolds Aluminum, and it stayed on the air until June 1955.[2](https://www.worldradiohistory.com/BOOKSHELF-ARH/History/Total-Television-Programming-1948-1991-McNeil.pdf) • [13](https://eyesofageneration.com/remember-mr-peepers-this-photo-was-taken-by-mike-mathews-mother-in/)
The show's humor came from gentle exaggerations of mundane situations rather than jokes or broad physical gags, a style Cox insisted on.[11](https://www.tvinsider.com/people/wally-cox/) The supporting cast included [Tony Randall](https://www.edgepedia.org/tony-randall) as history teacher Harvey Weskit, Marion Lorne as Mrs. Gurney, [Jack Warden](https://www.edgepedia.org/jack-warden) as the coach, and Patricia Benoit as school nurse Nancy Remington, whom Peepers married in a May 1954 episode that ranked among the highest-rated television broadcasts of that year.[2](https://www.worldradiohistory.com/BOOKSHELF-ARH/History/Total-Television-Programming-1948-1991-McNeil.pdf) • [5](https://www.imdb.com/name/nm0185281/) The series earned Emmy nominations, and Cox received nominations as Best Comedian of 1953 and Best Male Star of a Regular Series in 1954.[5](https://www.imdb.com/name/nm0185281/) Because the episodes were broadcast live, few kinescopes (Films made of live TV broadcasts; how episodes were preserved) survive, and the show became widely accessible again only when the UCLA Film & Television Archive released DVD sets of its first two seasons.[11](https://www.tvinsider.com/people/wally-cox/) • [14](https://cinema.ucla.edu/blog/watching-home-movies-with-mister-peepers/)
## Later career
After *Mister Peepers* ended, Cox starred as a newspaper proofreader in *The Adventures of Hiram Holliday* (1956–57), which was scheduled against ABC's *Disneyland* and was not a success.[6](https://www.worldradiohistory.com/BOOKSHELF-ARH/Radio-Programming/Radio-Programming/The-Encyclopedia-of-American-Television-Lackman-2002.pdf) • [10](https://www.allmusic.com/artist/wally-cox-mn0000814216) He never again headlined a live-action series, but he worked steadily in guest appearances on series such as *The Beverly Hillbillies*, *Bonanza*, *The Twilight Zone*, *Get Smart*, and *Here's Lucy*, and in supporting film roles in *State Fair* (1962), *Spencer's Mountain* (1963), *The Yellow Rolls-Royce* (1964), *The Bedford Incident* (1965), and *The Barefoot Executive* (1971).[4](https://www.worldradiohistory.com/BOOKSHELF-ARH/Radio-Programming/TV-Stars-The-Complete-Directory-to-Prime-Time-1964-Present-B--221117.pdf) • [5](https://www.imdb.com/name/nm0185281/) • [15](https://www.rottentomatoes.com/celebrity/wally_cox) His turn as Seaman Merlin Queffle, the sonar operator in *The Bedford Incident*, and as the potential suicide Wally Haverstraw in a 1970 *Bill Cosby Show* episode are cited as examples of a wider range the industry seldom used.[1](https://www.imdb.com/name/nm0185281/bio/)
Two later roles kept him in the public eye. From 1966 until his death he was a regular panelist on *The Hollywood Squares*, occupying the upper left-hand cubicle and, unlike many of the panelists, apparently delivering unscripted, sarcastic one-liners.[5](https://www.imdb.com/name/nm0185281/) From 1964 to 1973 he voiced the title character of the [Saturday-morning cartoon](https://www.edgepedia.org/saturday-morning-cartoon) *Underdog*, along with the hero's alter ego, the humble Shoeshine Boy.[4](https://www.worldradiohistory.com/BOOKSHELF-ARH/Radio-Programming/TV-Stars-The-Complete-Directory-to-Prime-Time-1964-Present-B--221117.pdf) • [8](https://www.nndb.com/people/722/000091449/) He also wrote two books, *My Life As A Small Boy* (1961) and *Ralph Makes Good* (1965).[8](https://www.nndb.com/people/722/000091449/)
## Death and the Brando friendship
Cox was found dead at his Bel-Air home on February 15, 1973, at age 48.[3](https://www.latimes.com/local/obituaries/la-me-wally-cox-19730216-story.html) [Los Angeles County](https://www.edgepedia.org/los-angeles-county) coroner Dr. Thomas F. Noguchi reported severe coronary disease and said death appeared to be due to a heart attack; the sedative Placidyl was found at a therapeutic level.[16](https://occgs.com/projects/rescue/family_files/files/COX%20Family.pdf) Some newspapers described an accidental overdose of sedatives, while Brando's autobiography called it a heart attack.[1](https://www.imdb.com/name/nm0185281/bio/) In accordance with his wishes there were no funeral services, and his body was cremated.[17](https://mdh.contentdm.oclc.org/digital/api/collection/colmo5/id/5737/download)
Brando flew in from Tahiti to handle the cremation and kept Cox's cremated remains hidden in a closet for three decades.[11](https://www.tvinsider.com/people/wally-cox/) • [1](https://www.imdb.com/name/nm0185281/bio/) According to Brando's son Miko, both his father's ashes and Cox's were scattered at the same time in [Death Valley](https://www.edgepedia.org/death-valley), California, in a ceremony following Brando's death.[1](https://www.imdb.com/name/nm0185281/bio/)
Cox married three times: Marilyn Jenny Gennaro (1954–1961), Milagros Tirado Fink (1963–1966), and Patricia Tiernan (1967 until his death).[1](https://www.imdb.com/name/nm0185281/bio/) Off screen he was athletic, rode motorcycles, and enjoyed rock collecting and birdwatching.[4](https://www.worldradiohistory.com/BOOKSHELF-ARH/Radio-Programming/TV-Stars-The-Complete-Directory-to-Prime-Time-1964-Present-B--221117.pdf) • [18](https://mercurie.blogspot.com/2024/12/the-centenary-of-wally-coxs-birth.html)
