In the preface to The Americans, Jack Kerouac writes, “Robert Frank, Swiss, unobtrusive, nice, with that little camera that he raises and snaps with one hand he sucked a sad poem right out of America onto film, taking rank among the tragic poets of the world.” Frank’s book of photography became a cultural force when it arrived in America in 1959, a year after its initial publication in France. But the “Swiss, unobtrusive, nice” photographer had far more to capture than what was in the pages of The Americans. Frank’s artistic career continued for another 60 years. “Life Dances On: Robert Frank in Dialogue” highlights the work made in the decades that followed Frank’s acclaimed book, showcasing short films and other photographic endeavors. —Zack Hauptman
