Richard Avedon at 100

May 15 is the 100th birthday of renowned American photographer Richard Avedon. A new exhibition at Gagosian, Avedon 100, celebrates his centennial by presenting a collection of his photographs selected by over 150 people, from Spike Lee, Brooke Shields, Elton John, and more. Sarah Elizabeth Lewis, professor and art and cultural historian who wrote an essay for the exhibition catalog, joins us to discuss the importance of Avedon's work in the history of photography. Avedon 100 is open through June 24.
