Curtis Arnoux Peters, Jr., known professionally as Peter Arno, was an American cartoonist. He contributed cartoons and 101 covers to The New Yorker from 1925, the magazine's first year, until 1968, the year of his death. In 2015, New Yorker contributor Roger Angell described him as "the magazine's first genius".

The New Yorker is an American magazine featuring journalism, commentary, criticism, essays, fiction, satire, cartoons, and poetry. The New Yorker was founded on February 21, 1925, by Harold Ross and his wife Jane Grant, a reporter for The New York Times. Together with entrepreneur Raoul H. Fleischmann, they established the F-R Publishing Company and set up the magazine's first office in Manhattan. Ross remained the editor until his death in 1951, shaping the magazine's editorial tone and standards.
