James Montgomery Flagg Is Born

James Montgomery Flagg, creator of this illustration of Uncle Sam, was born on June 18, 1877, in Pelham Manor, New York.

Flagg claimed that his illustration, an indelible American icon, had become the most famous poster in the world. Dressed in his own Uncle Sam suit, he used himself as the model for this poster and his other Uncle Sam illustrations.

An illustrator and portrait artist best known for his commercial art, Flagg contributed forty-six works in support of the war effort during World War I. Leslie's Weekly first published his picture of Uncle Sam as the cover of the July 6, 1916, issue with the title "What Are You Doing for Preparedness?" More than four million copies were printed between 1917 and 1918. The image also was used extensively during World War II.

James Montgomery Flagg (June 18, 1877 – May 27, 1960) was an American artist and illustrator. He worked in media ranging from fine art painting to cartooning, but is best remembered for his posters.

Flagg was born in Pelham Manor, New York. He was enthusiastic about drawing from a young age, and had illustrations accepted by national magazines by the age of twelve years. By fourteen he was a contributing artist for Life magazine, and the following year was on the staff of another magazine, Judge. From 1894 through 1898, he attended the Art Students League of New York. He studied fine art in London and Paris from 1898–1900, after which he returned to the United States, where he produced countless illustrations for books, magazine covers, political and humorous cartoons, advertising, and spot drawings. Among his creations was a comic strip that appeared regularly in Judge from 1903 until 1907, about a tramp character titled Nervy Nat.
