Alice Neel  was an American visual artist, who was particularly well known for oil painting and for her portraits depicting friends, family, lovers, poets, artists and strangers. Her paintings are notable for their expressionistic use of line and color, psychological acumen, and emotional intensity. Neel was called "one of the greatest portrait artists of the 20th century" by Barry Walker, curator of modern and contemporary art at the Museum of Fine Arts, Houston, which organized a retrospective of her work in 2010.
