Sarah Greenough, senior curator and head of the department of photographs, National Gallery of Art, and Philippe Séclier, filmmaker. Fifty years after the publication of The Americans, French filmmaker Philippe Séclier retraced Robert Frank's journey through the United States in 1955 and 1956. Working with only a small digital camera, Séclier explores the legacy of the 1950s and the impact of the book on photography and culture in this 15,000-mile odyssey through present-day America. In this podcast, Greenough and Séclier discuss his tribute, four years in the making, to the renowned photographer.
