Julian Alden Weir (August 30, 1852 – December 8, 1919) was an American impressionist painter and member of the Cos Cob Art Colony near Greenwich, Connecticut. Weir was also one of the founding members of "The Ten", a loosely allied group of American artists dissatisfied with professional art organizations, who banded together in 1898 to exhibit their works as a stylistically unified group.
Weir was born on August 30, 1852, the second to last of sixteen children, and raised in West Point, New York. His father was painter Robert Walter Weir, a professor of drawing at the Military Academy at West Point who taught such artists as James Abbott McNeill Whistler. His older brother, John Ferguson Weir, also became a well-known landscape artist who painted in the styles of the Hudson River and Barbizon schools. He was professor of painting and design at Yale University from 1869, starting the first academic art program on an American campus.
Julian Weir received his first art training at the National Academy of Design in the early 1870s before enrolling at the École des Beaux-Arts in Paris in 1873. While in France he studied under the famous French artist Jean-Léon Gérôme, and became good friends with Jules Bastien-Lepage. Weir also encountered impressionism for the first time, and reacted strongly: "I never in my life saw more horrible things...They do not observe drawing nor form but give you an impression of what they call nature. It was worse than the Chamber of Horrors." He complained about the Impressionists in a letter from April 15, 1877 to his parents saying, "They do not observe drawing nor form but give you an impression of what they call nature". As a conservative academic painter at this stage in his career, Weir was esteemed by his European peers during his training years.
