If you have 90 minutes this weekend, take time to watch DuSable to Obama: Chicago’s Black Metropolis. DuSable is Jean Baptiste DuSable, Chicago’s first settler and Obama, of course, is President Barack Obama. This 2010 documentary produced by WTTW in association with the Chicago Defender, the Chicago History Museum, and the DuSable Museum of African American History, covers a lot of ground. So much so, I hope it spawns additional documentaries, as I would love to learn even more about some of the topics explored here. Historians, artists and performers, business leaders and community workers all talk about the contributions of African Americans to Chicago’s history. DuSable to Obama: Chicago’s Black Metropolis is not just a chronicling of Chicagoan Black history, it is American history. Explore more at the film’s web site.
