The Marx Brothers were a comedic ensemble consisting of five brothers: Groucho, Chico, Harpo, Gummo, and Zeppo. They were active in vaudeville, theater, and film from the 1910s to the 1950s. They were known for their comedic style, which included physical comedy, satire, and witty one-liners.

Groucho Marx (Julius Henry Marx, 1890-1977) was the leader of the group and the most famous member. He was known for his distinctive greasepaint mustache, cigar, and quick wit. He often played the role of the clever, wisecracking character.

Chico Marx (Leonard Marx, 1887-1961) was known for his comical accent and piano playing skills. He often played the role of the con artist or the schemer.

Harpo Marx (Adolph Marx, 1888-1964) was known for his silence, his harp playing and his ability to communicate through pantomime. He often played the role of the mute, childlike character.

Gummo Marx (Milton Marx, 1892-1977) was the oldest of the brothers and left the group in 1913 to pursue a different career.

Zeppo Marx (Herbert Marx, 1901-1979) was the youngest of the brothers and often played the straight man or the romantic lead. He left the group in 1933 to pursue a career in business.

The Marx Brothers made 13 feature films together, and their most famous films include "Duck Soup" (1933), "A Night at the Opera" (1935) and "A Day at the Races" (1937). They were known for their irreverent and satirical humor, and their films often mocked societal norms and political figures of their time. They were considered one of the greatest and most influential comedic acts of the 20th century and their films continue to be enjoyed by audiences today.
