Architect On New Black History Museum Design

The way Americans learn about African American history is largely shaped by architect Philip Freelon. He's designed most of the country's major African American history and culture museums — from the International Civil Rights Center and Museum in Greensboro, NC, to the Museum of the African Diaspora in San Francisco. And Wednesday there was a groundbreaking ceremony on the National Mall for his highest profile project to date — the new Smithsonian devoted to African American history and culture. Freelon stopped by after the ceremony to talk with Melissa Block about the museum and his design philosophy.
