He also appeared as Uncle Tonoose on Danny Thomas' sitcom Make Room for Daddy, twice on I Love Lucy, and as the Mad Hatter along with Daws Butler, Dolores Starr, Stanley Adams, Francis Condie Baxter and Cheryl Callaway in The Alphabet Conspiracy (1959).

[2] Four years later, a newspaper reported about his role on Hedda Hopper's Hollywood: "But at the mike, he's equally convincing as old men, drunks, dialeticians, or Shakesperean tragedians.

He became a heavy mortar crewman then was sent to the Philippines as an engineer laborer until fellow actor Jack Kruschen obtained his release for service with the Armed Forces Radio Network.

Even as a younger man, Conried appeared much older than his actual age and he was frequently cast as middle-aged or even elderly pompous, scholarly types.

His impeccable diction and inimitable growl were well suited to the roles he played, whether portraying the dim Professor Kropotkin on the radio show My Friend Irma or as comic villains and mock-sinister or cranky types.

In 1949, while filming the movie version of My Friend Irma, character actor Felix Bressart, cast as Professor Kropotkin, died suddenly during production.

[8] Theodor Geisel, better known as children's author Dr. Seuss, was preparing a documentary feature largely made up of captured Japanese newsreel footage, Design for Death (1948).

[citation needed] Geisel remembered Conried when he was preparing an expensive Technicolor fantasy, The 5,000 Fingers of Dr. T. (1953), which included the dominant role of a demanding, dictatorial piano teacher.

In 1970, Conried reflected on the film's poor box-office take in an interview with Leonard Maltin: "The picture never made its print money back.

He voiced the character of Snidely Whiplash in the Dudley Do-Right segments of The Rocky and Bullwinkle Show, and Professor Waldo P. Wigglesworth on Hoppity Hooper.

During that show he had a tightly scripted segment where he absurdly interviewed guest stars and celebrities, while usually mistaking their identities, misunderstanding answers, taking umbrage or getting into mock disagreements.

The episode, an analysis by Leonard Bernstein, showing the powerful effect of music in opera, featured Conried as Marcello in a spoken dramatization of Act III of Puccini's La Bohème.

The program demonstrated the effect of the music in La Bohème by having actors speak portions of the libretto in English, followed by opera singers singing the same lines in the original Italian.

In 1977, Conried joined the cast for the second and final season of The Tony Randall Show in the recurring role of Judge Franklin's irascible father, Wyatt.
