Born in Barranquilla, Colombia, he studied at the Art Students League of New York from 1946 till 1950. He is one of the leading members of the New York School of artists and writers. He lives and works in New York City.
Knox Martin is the oldest son of Lieutenant William Knox Martin, a Virginia-born early aviation pioneer and flyer, and his wife Isabel Vieco, who were married in the Canal Zone in Panama in 1921. Knox Martin Sr., painter, poet, early test pilot, was the first man to fly over the Andes mountains. Six years after his marriage, Martin Sr. was fatally injured in an automobile accident in Watertown, New York.
His widow Isabel relocated with her three young sons from Salem, Virginia to New York City.
After serving in the United States Coast Guard during World War II, Knox Martin attended the Art Students League of New York on the G.I. Bill from 1946 to 1950, where he studied with Harry Sternberg, Vaclav Vytlacil, Will Barnet, and Morris Kantor.
In 1954, Martin's friend Franz Kline placed a painting of his in the Stable Gallery Annual. Charles Egan of the Charles Egan Gallery saw Martin's painting at the Stable Gallery and asked him to show his work in a one-man show for the tenth anniversary of the Egan Gallery.
Knox Martin is best known for his repertory of signs and symbols that allude to nature and, in particular, to the female form. Flatly and freely painted in brilliant colors, his works have often been executed on a grand scale, as in the outdoor wall painting, Woman with bicycle, at West Houston and MacDougal Streets in Manhattan. He mostly creates painting, sculpture and wall paintings using media such as acrylic, collage, fresco, ink drawing (pen and ink), mixed media/multimedia, and oil.
One of his wall paintings in New York City is the twelve-story mural Venus. Painted in 1970, it is located on the south side of Bayview Correctional Facility at 19th Street and the West Side Highway.
"Traditionally the goddess of love and fertility, Venus represents woman, erotic and supple, but it also conveys Knox Martin's love affair with New York. Venus is his love poem to the city where he has always lived, a place that is part of his being. The feminine, curvilinear shapes of the image are in direct contrast with the straight forms that intersect the composition. The overwhelming size of this enormous mural only intensifies the experience of female shapes, the linear aspects of the painted composition, and of the surrounding architecture. In an era when art was reaching out to the masses with pop culture, this huge mural was Knox Martin's way of touching a public that would never venture into an art gallery."
