Martha Kellogg Jackson

Martha Jackson (; January 17, 1907 – July 4, 1969) was an American art dealer, gallery owner, and collector. Her New York City based Martha Jackson Gallery, founded in 1953, was groundbreaking in its representation of women and international artists, and in establishing the op art movement.

Biography Jackson was born Martha Kellogg on January 17, 1907, in Buffalo, New York. She was born into two prominent Buffalo families, the daughter of Cyrena (née Case; 1884-1931) and Howard Kellogg (1881-1969). She had two brothers, Spencer Kellogg II and Howard Kellogg, Jr. Jackson's mother's family founded and operated W. A. Case & Son Manufacturing Company which was eventually purchased in 1952 by what is now Covanta. Jackson's father was president of Spencer Kellogg & Sons, Inc., a linseed oil firm founded by his father, which became a division of Textron in 1961. In 1949, following her interest in making art, Jackson moved to New York to attend the Hans Hofmann School of Art. Already an art collector, she took Hoffman's advice to become an art dealer, using sales from her personal collections to fund her gallery. The marriage ended in divorce. Among those in her stable were Henry Moore, Louise Nevelson, Lynn Chadwick, Norman Carton, Philip Pavia, Zoltán Kemény, The gallery also exhibited works by Francis Bacon and Marino Marini, New York School painters like Willem de Kooning, Hans Hofmann, and Adolph Gottlieb, deceased Americans Milton Avery, Alexander Calder, Arshile Gorky, and Marsden Hartley, and emerging artists Lawrence Calcagno, John Hultberg, Lee Krasner, and Norman Bluhm Lee Krasner, Marisol (Escobar), Barbara Hepworth, and Grace Hartigan. New Forms — New Media exhibition, a subversive of art in the Dadaist tradition. In the fall of 1960, the gallery launched a second installment of the exhibit, New Forms New Media II, which ran from September 22- October 22.

In 1961 Jackson opened Environments, Situations, Spaces, a follow-up to the New Forms — New Media shows. This exhibition consisted of site-specific and interactive works including Spring Cabinet, room of drippy paint buckets by Jim Dine; Yard, a courtyard full of salvaged tires by Allan Kaprow; as well as a recreation of Claes Oldenburg's Store.

Artworks from the Martha Jackson Collection were exhibited at the National Museum of American Art in 1985. The exhibition was organized by independent curator Jillian Russo, accompanied by an eponymous essay and catalog.

Martha Jackson is portrayed in the 2022 Geraldine Brooks best seller historic novel, Horse, based upon the life of the race horse Lexington.
