By the numbers: Oprah donated how much to the Smithsonian?
$12 million -- That's the whopping number of dollars Oprah Winfrey handed over to the Smithsonian National Museum of African American History and Culture, the museum announced Tuesday, according to the Washington Post. Winfrey's name will adorn a 350-seat theater in the new museum, which is slated to open in 2015 on the National Mall. She already donated $1 million to the project in 2007 and has served on the museum's advisory council since 2004.
