Recently we reported on the Chicago Historical Society's plans to revamp the museum. Yesterday, days after revealing those plans, CHS President Lonnie Bunch announced that he will be leaving the city for Washington D.C.'s Smithsonian and their National Museum of African American History and Culture. Bunch will remain at CHS until June when Russell Lewis, director of collections and research, will step up as interim-president. (Also on board at the Smithsonian NMAAHC? Oprah. But don't worry -- she's not moving or anything.)
