If we're talking characters who are human, "Silent Bob" is a character in Clerks I and Clerks II. He does not speak. Harpo Marx of the Marx Brothers never spoke on screen. If you were thinking of something else, let us know!!!
Groucho Marx's birth name is Julius Henry Marx.

Ivan Marx was born in 1921, in Illinois, USA.
He never "spoke" in the Marx Brother films but he did speak in one movie. It was called Too Many Kisses (1925). But, it was a silent movie. The audience saw him move his lips and then read the title card. According to Wikipedia, this is what is said about Harpo "speaking" in the Marx brother's movies: In the Marx Brothers' movie At the Circus (1939), however, Harpo speaks in a movie with the brothers in the scene in which he visits the room of Little Professor Atom (Jerry Maren), Harpo sneezes, clearly saying "At-choo!". In A Night in Casablanca, Harpo also "speaks" in the scene where he is taste-testing Groucho's food by acting like a seal and vocalizing seal sounds. It is also implied that Harpo is singing in the opening scene of Monkey Business (1931), where the four Marx Brothers, stowed away in barrels aboard a cruise liner, sing a four-part harmony of "Sweet Adeline."
