John Marin was an American painter of the modernist movement. Marin was born in Rutherford, New Jersey but spent much of his childhood in the town of Weehawken. Marin studied at Stevens Institute of Technology for a year before realizing his interest in fine art. In 1899 Marin enrolled at the Pennsylvania Academy of the Fine Arts in Philadelphia where he studied under Thomas Pollock Anshutz and William Merritt Chase.

Marin furthered his studies in Europe, where he remained for six years. Marin panted in travelled landscapes in France, Holland, Belgium, England and Italy. During his travels, Marin mostly painted with watercolors. His paintings were atmospheric and abstract, using the transparent and opaque qualities of his preferred medium.

Eventually Marin returned to the United States and settled in New York City. Marin was well received in New York and exhibited frequently. Marin had his first solo exhibition at the Alfred Stieglitz Gallery in 1909. The show was the beginning of a long working relationship with Stieglitz, who gave Marin financial and moral support.

Marin maintained a studio in New York City for several years, where he continued to paint and build a national reputation for his modernist landscapes. Marin’s work is now in American Art collections across the country. Major New York museums such as the Metropolitan Museum of Art, the Museum of Modern Art, Whitney Museum of Art and the Brooklyn Museum all boast paintings by Marin. Marin’s work can also be found in Chicago, Cleveland, Boston and Washington D.C museums.
