Hans Hofmann, a representative of Abstract Expressionism and American Modernism during the 20th century with European roots, had a fundamental influence as a teacher on the development of modern art in America. His brightly coloured paintings, watercolours and drawings can now be discovered in a European retrospective. From 1904 until 1914, the painter Hans Hofmann (1880 1966), who was a friend of Picasso, Braque, Matisse, the Fauves and Robert and Sonia Delaunay, witnessed and absorbed the new art in Paris, the centre of European art. In his art school, founded in Munich in 1915, he became a mediator of French modernism and achieved international fame as an art teacher. In 1932 he emigrated to the United States and two years later opened the Han s Hofmann School of Fine Arts in New York. He influenced a new generation of American artists, including Jackson Pollock, Helen Frankenthaler and Barnett Newman.
