President, Ariel Investments
Last year, Chicago asked about Hobson, then No. 29, “How much more powerful can she get?” Plenty, it turns out. Second in command at the country’s largest minority-owned investment firm, a director of three corporate giants, and an on-air contributor to CBS News, she has also become a Chicago benefactress par excellence. In 2014, she and her husband, George Lucas (see below), donated $25 million to the University of Chicago Laboratory Schools, and she helped the city land the future Lucas Museum of Narrative Art.
