The Smithsonian’s National Museum of African-American History and Culture broke ground Wednesday with President Obama onsite for the occasion. The new facility is set to open in 2015 and its founding director, Lonnie Bunch, has already raised nearly $100 million and collected roughly 20,000 artifacts for the museum. The Pittsburgh Post -Gazette reported that the effort has left executive directors of smaller black museum around the country, like Charmaine Jefferson of the California African American Museum, worried about the competition.
