The Family of Man was an ambitious photography exhibition curated by Edward Steichen, the director of the New York City Museum of Modern Art's (MoMA) Department of Photography. According to Steichen, the exhibition represented the "culmination of his career." The title was taken from a line in a Carl Sandburg poem. The Family of Man was first shown in 1955 from January 24 to May 8 at the New York MoMA, then toured the world for eight years to record-breaking audience numbers. Commenting on its appeal, Steichen said the people "looked at the pictures, and the people in the pictures looked back at them. They recognized each other." The physical collection is archived and displayed at Clervaux Castle in Luxembourg (Edward Steichen's home country; he was born there in 1879 in Bivange). It was first presented there in 1994 after restoration of the prints.In 2003 the Family of Man photographic collection was added to UNESCO's Memory of the World Register in recognition of its historical value.
