Groucho Marx (born Julius Henry Marx, 1890–1977) was an American comedian, actor, and writer best known as the sharp-tongued, wisecracking leader of the legendary Marx Brothers. With his trademark greasepaint mustache, exaggerated eyebrows, bent cigar, and loping walk, he became one of the most recognizable figures in 20th-century comedy. Groucho rose to fame in vaudeville and on Broadway before starring in classic films such as “Duck Soup” and “A Night at the Opera,” where his rapid-fire one-liners and surreal wordplay redefined screen humor. He later became a popular radio and television personality, hosting the quiz show “You Bet Your Life,” where his ad-libbed jokes with contestants cemented his reputation as a master of improvisation. Groucho’s influence can be seen in generations of comedians who followed, and he remains an enduring icon of smart, subversive comedy.
