The Portland Art Museum in Oregon has announced a monumental exhibition that will present masterpieces from the collection of Microsoft co-founder and philanthropist Paul G. Allen. “Seeing Nature: Landscape Masterworks from the Paul G. Allen Family Collection” will feature approximately 40 paintings by Claude Monet, Edouard Manet, J.M.W. Turner, Vincent van Gogh, Gustav Klimt, Edward Hopper, Georgia O’Keeffe, and others.

The exhibition, which spans five centuries of European and American landscape painting, was organized by the Portland Art Museum, the Seattle Art Museum, and the Allen Family Collection. It will debut at the Portland Art Museum in October 2015. It will then travel to The Phillips Collection in Washington, D.C., the Minneapolis Institute of Arts, and the New Orleans Museum of Art before closing at the Seattle Art Museum in early 2017.

The exhibition explores the evolution of landscape painting from the early Impressionists’ direct observations of nature to the more subjective works of the Post-Impressionists and the individualized perspectives that 20th-century artists brought to traditional landscape subjects.

Brian Ferriso, the Marilyn H. and Dr. Robert B. Pamplin Jr. Director of the Portland Art Museum, said, “Paul Allen is one of the Northwest’s most significant art collectors and philanthropists. His willingness to share his landscape masterpieces with our visitors continues his exceptional generosity and is a wonderful opportunity to be inspired by works of art that reflect his personal vision.”
