Robert Frank (b. 1924) is one of the most acclaimed photographers of the 20th century. His seminal book, The Americans, is arguably the most influential publication of photography among artists that followed. In 2009, a major substantial touring monographic exhibition and scholarly catalogue organized by Sarah Greenough made stops at the National Gallery of Art, Metropolitan Museum of Art, and the San Francisco Museum of Modern Art. Looking In: Robert Frank's The Americans coincides with the 50th anniversary of the publication of The Americans, first released in 1958 by Parisian publisher Robert Delpire, and in 1959 by Grove Press, which made the book available to a wider audience.
