Then, in 1948, when Janis was 52 years old, he and Harriet opened the Sidney Janis Gallery which was located at 15 E. 57th Street in Manhattan sharing the fourth floor with the
Betty Parsons Gallery. The gallery soon acquired a strong reputation by mounting scholarly, curated exhibitions of
Léger, Mondrian, the
Fauves, the
Futurists, and
de Stijl artists. During the 1950s, the gallery became a powerhouse of contemporary
avant-garde art. In 1952, Janis gave
Jackson Pollock the first of three solo shows. The gallery represented
Arshile Gorky,
Willem de Kooning,
Franz Kline,
Mark Rothko,
Robert Motherwell,
Phillip Guston,
Adolph Gottlieb,
William Baziotes, and
Josef Albers. In addition to his promotion of the
Abstract Expressionists, Janis become the first blue chip gallery to show
Pop art. In the fall of 1962 he organized the groundbreaking exhibition, the
International Exhibition of the New Realists, a survey of contemporary
Pop art and the seemingly related
Nouveau Réalisme movement. The exhibition was located in a temporary rented storefront at 19 W. 57th Street. Robert Motherwell, Mark Rothko, Phillip Guston and Adolph Gottlieb left the gallery as a protest. The Sidney Janis Gallery soon became a leading exhibitor and dealer in Pop art, representing
Claes Oldenburg,
Jim Dine,
Tom Wesselmann,
George Segal,
Öyvind Fahlström, and
Marisol. By placing the new work in the context of great modern art, Sidney Janis focused critical eyes on contemporary art in a different, brilliant and discriminating way. He continued throughout to show
Giacometti, Mondrian (whose estate he acquired),
Arp,
Magritte,
Dubuffet,
Duchamp,
Léger, and
Picasso, interspersing these exhibitions with solo shows and group shows of trend-setting contemporary artists . As a collector, Sidney Janis had an unparalleled eye. In 1967, he donated 103 works from his collection to the
Museum of Modern Art, including six late Mondrian oils,
Boccioni's
Dynamism of a Football Player, and
Picasso's
Artist and Model. MoMA's founding director,
Alfred Barr, declared that this donation was "unequaled among the great gifts" the museum had received. The gallery moved in the 1980s to 110 W. 57th Street. In 1984, the French Government awarded Mr. Janis its highest honor for distinguished contribution to cultural life, Commandeur de l'Ordre des Arts et des Lettres. He received the New York Mayor's Award of Honor for Arts and Culture in 1987. Sidney Janis remained active at the gallery through his later years, organizing the unique
Mondrian + Brâncuși exhibition in 1982, when he was 86 years old. He died at the age of 93 in New York in late 1989. The gallery continued under the direction of Janis' son Carroll and grandson David Janis. In the final decade of the century, the Janis Gallery continued to mount significant exhibitions, including "Mondrian: Flowers" a rare gathering of an extensive group of floral images by the seminal abstract artist. ==Impact in Art==
