Peggy Cass received acting training at HB Studio^[1] in New York City and eventually landed the lead role of Billie Dawn in a traveling production of Born Yesterday.^{[citation needed]}

Cass made her Broadway debut in 1949 with the play Touch and Go. She portrayed Agnes Gooch in Auntie Mame on Broadway and in the film version (1958), a role for which she won the Tony Award for Best Supporting Actress, and received an Oscar nomination for Best Supporting Actress.^[2]

She was cast as "First Woman" in the nine-member ensemble of the 1960 Broadway revue A Thurber Carnival, adapted by James Thurber from his own works.^[3] She played several characters throughout the performance, including: the mother in "The Wolf at the Door", the narrator of "The Little Girl and the Wolf", a nameless American tourist (who insisted Macbeth was a murder mystery), Miss Alma Winege in "File and Forget" (who wanted to ship to Mr. Thurber 36 copies of Grandma Was a Nudist, which he did not order), Mrs. Preble in "Mr. Preble Gets Rid of His Wife", Lou in "Take Her Up Tenderly" (who was helping to make old poetry more cheerful), and Walter Mitty's wife.^[3]

In 1961, she played Mitzi Stewart in the movie Gidget Goes Hawaiian. In 1964, she starred as First Lady Martha Dinwiddie Butterfield in the mock-biographical novel First Lady: My Thirty Days in the White House. The book, written by Auntie Mame author Patrick Dennis, included photographs by Cris Alexander of Cass, Dody Goodman, Kaye Ballard and others who portrayed the novel's characters.^[4]

In the late 1960s and early 1970s, Cass succeeded other actresses in Don't Drink the Water (as Marion Hollander) and in Neil Simon's Plaza Suite, and played Mollie Malloy in two revival runs of The Front Page. She also appeared in the 1969 film comedy If It's Tuesday, This Must Be Belgium. In the 1980s, she returned to the stage in 42nd Street and in the 1985 run of The Octette Bridge Club.^[2]

One of Cass's earliest television roles was as Elinore Hathaway in The Hathaways, a 26-episode situation comedy that aired on ABC from October 6, 1961, to March 30, 1962.^{[citation needed]} She starred with Jack Weston as suburban Los Angeles "parents" to a trio of performing chimpanzees. Weston portrayed Walter Hathaway, a real estate agent, and Cass was his zany wife, "mother" and booking agent for the Marquis Chimps, named Candy, Charlie and Enoch.^{[citation needed]}

Cass filled in as announcer on Jack Paar's late night talk show that aired in the 1970s on ABC.^{[citation needed]}

In addition to her work with Paar, Cass's notable television work includes appearances on many game shows, on shows based mainly in New York City. She was a regular panelist on To Tell the Truth from 1960 through its 1990 revival, appearing in most episodes in the 1960s and 1970s.^[5] She was also a panelist on the pilot of the 1960s version of Match Game.^{[citation needed]}

On To Tell the Truth and other series, she often displayed near-encyclopedic knowledge of various topics and would occasionally question the logic of some of the "facts" presented on the program. Cass appeared on What's My Line? in 1963, and made several appearances on the $10,000 & $20,000 Pyramid hosted by Dick Clark from 1973 to 1980, as well as the nighttime version, which was titled The $25,000 Pyramid (1974–1979), hosted by her friend Bill Cullen. All three of these versions were taped in New York City. She also appeared in the late 1970s on Shoot for the Stars hosted by Geoff Edwards, which was another game show that partnered contestants with celebrities, also filmed in New York City.^{[citation needed]}

In 1983, she appeared in the New Amsterdam Theatre Company's concert staging of Kurt Weill and Ogden Nash's One Touch of Venus as Mrs. Kramer, with Susan Lucci as her daughter, as well as Lee Roy Reams, Ron Raines, and Paige O'Hara as the titular Venus. In the spring of 1991, she participated in a concert staging of Cole Porter's Fifty Million Frenchmen at New York City's French Institute Alliance Française as Mrs. Gladys Carroll, singing Porter's "The Queen of Terre Haute".^[6][7]

In 1987, Cass was featured in the early Fox sitcom Women in Prison. Aside from sitcoms, she played the role of H. Sweeney on the NBC afternoon soap opera The Doctors from 1978 to 1979.^{[citation needed]}

Cass appeared on the pilot episode of Major Dad on September 17, 1989.^[8] She portrayed Esther Nettleton, a civilian secretary working on the Marine base for Maj. John "Mac" MacGillis.
