The cartoon editor of The New Yorker for years was Lee Lorenz, who first began cartooning in 1956 and became a New Yorker contract contributor in 1958.[19] After serving as the magazine's art editor from 1973 to 1993 (when he was replaced by Françoise Mouly), he continued in the position of cartoon editor until 1998. His book The Art of the New Yorker: 1925–1995 (Knopf, 1995) was the first comprehensive survey of all aspects of the magazine's graphics. In 1998, Robert Mankoff took over as cartoon editor, and since then Mankoff has edited at least 14 collections of New Yorker cartoons.
