Sidney Janis (July 8, 1896 – November 23, 1989) was a wealthy clothing manufacturer and art collector who opened an art gallery in New York in 1948. His gallery quickly gained prominence, for he not only exhibited work by the Abstract Expressionists, but also European artists such as Pierre Bonnard, Paul Klee, Joan Miró, and Piet Mondrian. As the critic Clement Greenberg explained in a 1958 tribute to Janis, the dealer's exhibition practices had helped to establish the legitimacy of the Americans, for his policy "not only implied, it declared, that Jackson Pollock, Willem de Kooning, Franz Kline, Phillip Guston, Mark Rothko, and Robert Motherwell were to be judged by the same standards as Matisse and Picasso, without condescension, without making allowances." Greenberg observed that in the late 1940s "the real issue was whether ambitious artists could live in this country by what they did ambitiously. Sidney Janis helped as much as anyone to see that it was decided affirmatively." Biography Early life Sidney Janis was born in 1896 in Buffalo, New York, one of five children of a traveling salesman. A talented ballroom dancer, he left public high school in his senior year to travel on the eastern vaudeville circuit. Janis joined the Naval Reserve in 1917 and took courses to complete his high school diploma. After his discharge, he returned to Buffalo to work with an older brother who had a chain of shoe stores. On his frequent trips to New York, he met, courted, and in 1925 married Harriet Grossman, a writer passionate about music and the visual arts. Sidney and Harriet Janis visited as many art shows as they could. Sidney later maintained that visual experience was more important than schooling in developing an understanding and appreciation of art and the artist. Collecting In the mid-1920s, Sidney Janis opened his own shirt company, M'Lord. Its signature item was a two-pocket, short-sleeved shirt that he designed. As the business grew and prospered, so did the Janises' passion for collecting art. The couple made annual trips to Paris, where they met Mondrian, Picasso, Léger, Brâncuși, and other masters. By the early 1930s, they had acquired major works by Picasso, Matisse, De Chirico, Dalí, Mondrian, and the self-taught master Henri Rousseau. In New York, Sidney and Harriet Janis became friends with Arshile Gorky, Frederick Kiesler, and Marcel Duchamp, all of whom often visited their apartment. Career in art In
