Frederick Chapman was an American illustrator, who was stationed in London, and contributed sketches to the British and American editions of Vogue magazine.
In 1923, when Vogue did a spread on it's accredited artists, he was included, along with the sketch shown here, of a Parisienne wearing the new low-waisted style of coat, along with an animal-skin stole, and wide-brimmed hat.
In London Chapman was one of two artists, sharing duties with George Plank, a general illustrator in the Chapman mould. Vogue mentioned "Frederick Chapman was in London, was an illustrator who had set a distinctive example in his fashion illustration, unwhimsical, everyday, a style which others were to modify and develop." This is around 1923.
He was probably with Vogue from the end of World War I till the end of the 20's. Not much is known about him.
