Thomas Cowperthwait Eakins (* July 25, 1844 in Philadelphia, Pennsylvania; June 25, 1916 ibid.) was an American realistic painter.
He made photographs and sculptures, but became famous with his paintings. Among his most famous paintings are his Ruder paintings (see, for example, Max Schmitt in One), Die Klinik Gross (the most expensive painting of an American before the Second World War in 2006-2007), and Swimming, known for its homoerotic charisma. Eakins painted and drew over 500 paintings, watercolours and drawings, but sold very few during his lifetime. He found temporary recognition as a teacher. Today, Eakins is considered one of the most important American artists.
