Kroller-Muller Museum. The Kröller-Müller Museum is a national art museum and sculpture garden, located in the Hoge Veluwe National Park in Otterlo in the Netherlands. The museum, founded by art collector Helene Kröller-Müller within the extensive grounds of her and her husband's former estate, opened in 1938. It has the second-largest collection of paintings by Vincent van Gogh, after the Van Gogh Museum. The museum had 380,000 visitors in 2015. The Kröller-Müller Museum was founded by Helene Kröller-Müller, an avid art collector who, being advised by H.P. Bremmer, was one of the first to recognize Vincent van Gogh's genius and collect his works. In 1935, she donated her whole collection to the state of the Netherlands. In 1938, the museum, which was designed by Henry van de Velde, opened to the public. The sculpture garden was added in 1961 and the new exhibition wing, designed by Wim Quist, opened in 1977. The museum has a considerable collection of paintings by Vincent van Gogh, such as Cafe Terrace at Night, Sorrowing Old Man and a version of The Potato Eaters, making it the second-largest collection of Van Gogh paintings in the world. Apart from the Van Gogh paintings other highlights include works by Piet Mondrian, Georges-Pierre Seurat, Odilon Redon, Georges Braque, Paul Gauguin, Lucas Cranach, James Ensor, Juan Gris, and Pablo Picasso. The Kröller-Müller Museum is also famous for its large sculpture garden, within the forest park, of more than 75 acres and one of the largest in Europe, with a fine collection of modern and contemporary sculptures. The garden reflects Helene Kröller-Müller's conception of a symbiosis between art, architecture and nature. The collection includes works by Auguste Rodin, Henry Moore, Jean Dubuffet, Mark di Suvero, Lucio Fontana, Claes Oldenburg, Fritz Wotruba, Joep van Lieshout and many more. year visitors 2012 307,000 2013 330,000 2014 392,000 2015 380,000 Lisette Pelsers has been museum director of the Kröller-Müller Museum since 2012.
