The 50th anniversary of a groundbreaking publication will be celebrated in the nation's capital with the exhibition 'Looking In: Robert Frank's 'The Americans',' premiering January 18 through April 26, 2009, in the National Gallery of Art's West Building ground floor galleries. In 1955 and 1956, the Swiss-born American photographer Robert Frank (b. 1924) traveled across the United States to photograph, as he wrote, 'the kind of civilization born here and spreading elsewhere.' The result of his journey was 'The Americans,' a book that looked beneath the surface of American life to reveal a culture on the brink of massive social upheaval and one that changed the course of 20th-century photography.
