John Henry Vanderpoel (November 15, 1857 – May 2, 1911), born Johannes (Jan) van der Poel, was a Dutch-American artist and teacher, best known as an instructor of figure drawing. His book The Human Figure, a standard art school resource featuring numerous of his drawings based on his teaching at the School of the Art Institute of Chicago, was published in 1907.
Vanderpoel was born in the Haarlemmermeer, Netherlands, the seventh of ten children. His mother died in 1867, and in 1869 he emigrated with his father and siblings to the United States. He studied at the Chicago Academy of Design, which later became the School of the Art Institute of Chicago. In 1886 he went to Europe, studying for two years at Académie Julian in Paris with Gustave Boulanger and Jules Lefebvre.
Vanderpoel exhibited five paintings at the World's Columbian Exposition in Chicago in 1893, was a member of several artists' societies, and was elected president of the Chicago Society of Artists. He received a bronze medal at the Louisiana Purchase Exposition of 1904 in St. Louis. He worked with Lucille Wilcox Joullin during his stay in Chicago. Vanderpoel also created murals, including one on the ceiling of a theater at DePaul University and a sixty-foot painting at a Los Angeles hotel. In spite of his successes as a muralist and easel painter, Vanderpoel was better known as an instructor at the Art Institute, where he taught from 1880 until 1910. He was an influential teacher who adhered to the beaux-arts tradition while denouncing modernism. Among Vanderpoel's many students were artists J. C. Leyendecker,Frederick Carl Frieseke, and Georgia O'Keeffe, who wrote in her autobiography that Vanderpoel was "one of the few real teachers I have known." Vanderpoel's younger sister Matilda, an artist who, like him, had attended and then taught at the Art Institute, also had O'Keeffe as a student.
