An American modernist painter and writer, Marsden Hartley was known for his bold use of color, symbolic imagery, and expressive brushwork. Influenced by European avant-garde movements, especially Expressionism, he created deeply personal works that explored spirituality, identity, and the power of nature. His landscapes, still lifes, and abstract compositions reflect both his emotional intensity and his enduring connection to the rugged landscapes of his native Maine, establishing him as one of the pioneers of American modern art.
