Hirshhorn Museum and Sculpture Garden. The Hirshhorn Museum and Sculpture Garden is an art museum beside the National Mall, in Washington, D.C., the United States. The museum was initially endowed during the 1960s with the permanent art collection of Joseph H. Hirshhorn. It was designed by architect Gordon Bunshaft and is part of the Smithsonian Institution. It was conceived as the United States' museum of contemporary and modern art and currently focuses its collection-building and exhibition-planning mainly on the post-World War II period, with particular emphasis on art made during the last 50 years. The Hirshhorn is sited halfway between the Washington Monument and the US Capitol, anchoring the southernmost end of the so-called L'Enfant axis. The National Archives/National Gallery of Art Sculpture Garden across the Mall, and the National Portrait Gallery/Smithsonian American Art building several blocks to the north, also mark this pivotal axis, a key element of both the 1791 city plan by Pierre L'Enfant and the 1901 MacMillan Plan. The building itself is an attraction, an open cylinder elevated on four massive legs, with a large fountain occupying the central courtyard. Before architect Gordon Bunshaft designed the building, the Smithsonian staff reportedly told him that, if it did not provide a striking contrast to everything else in the city, then it would be unfit for housing a modern art collection. In the late 1930s, the United States Congress mandated an art museum for the National Mall. At the time, the only venue for visual art was the National Gallery of Art, which focuses on Dutch, French, and Italian art. During the 1940s World War II shifted the project into the background. Meanwhile, Joseph H. Hirshhorn, now in his forties and enjoying great success from uranium-mining investments, began creating his collection from classic French Impressionism to works by living artists, American modernism of the early 20th century, and sculpture. Then, in 1955, Hirshhorn sold his uranium interests for more than $50-million. He expanded his collection to warehouses, an apartment in New York City, and an estate in Greenwich, Connecticut, with extensive area for sculpture. A 1962 sculpture show at New York's Guggenheim Museum awakened an international art community to the breadth of Hirshhorn's holdings. Word of his collection of modern and contemporary paintings also circulated, and institutions in Italy, Israel, Canada, California, and New York City vied for the collection. President Lyndon B. Johnson and Smithsonian Secretary S. Dillon Ripley successfully campaigned for a new museum on the National Mall. In 1966, an Act of Congress established the Hirshhorn Museum and Sculpture Garden, Smithsonian Institution. Most of the funding was federal, but Hirshhorn later contributed $1-million toward construction. Joseph and his fourth wife, Olga Zatorsky Hirshhorn, visited the White House. The groundbreaking was in 1969 and Abram Lerner was named the founding Director. He oversaw research, conservation, and installation of more than 6,000 items brought from the Hirshhorns' Connecticut estate and other properties to Washington, DC. Joseph Hirshhorn spoke at the inauguration, saying: It is an honor to have given my art collection to the people of the United States as a small repayment for what this nation has done for me and others like me who arrived here as immigrants. What I accomplished in the United States I could not have accomplished anywhere else in the world. One million visitors saw the 850-work inaugural show in the first six months. In 1984, James T. Demetrion, fourteen-year director of the Des Moines Art Center in Iowa, succeeded Abram Lerner as the Hirshhorn's director. Art collector and retail store founder Sydney Lewis of Richmond, Virginia, succeeded Senator Daniel P. Moynihan as board chairman. Mr. Demetrion held the post for more than 17 years. Ned Rifkin became director in February 2002, returning to the Hirshhorn after directorship positions at the Menil Collection in Texas and the High Museum of Art in Atlanta, Georgia. Rifkin was previously chief curator of the Hirshhorn from 1986 until 1991. In October 2003, Rifkin was named Under Secretary for Art of the Smithsonian. In 2005, Olga Viso was named director of the Hirshhorn. Viso joined the curatorial department of the Hirshhorn in 1995 as assistant curator, was named associate curator in 1998, and served as curator of contemporary art from 2000 to 2003.
