Exelon Foundation donated $1 million to the National Museum of African American History and Culture, which opened Saturday in Washington, D.C.
The 400,000-square-foot museum on the National Mall documents the experience of African Americans in the United States, from the country's history in slave trade to its first black president.
"We're proud to support this museum and its essential role in telling the story of America in all its richness and complexity," said Exelon CEO and President Chris Crane, also chairman of the Exelon Foundation, in a statement. "Diverse perspectives and backgrounds are fundamental to understanding and celebrating who we are as a nation."
Exelon is the parent of Baltimore Gas & Electric. Co. The foundation's donation will support exhibitions and programs at the new Smithsonian museum.
The museum has 12 inaugural exhibitions, focused on history, culture and community.
The collection has more than 40,000 artifacts, including the remnants of a slave ship, a lace shawl that belonged to Harriet Tubman and Louis Armstrong's trumpet.
