The controversy over the late Chicago street photographer Vivian Maier’s legacy got a new twist this week. Few people have really known much about Maier’s long-lost brother Charles. He’s one of the key figures in court proceedings in Cook County that could determine who can print and sell Maier’s masterful portraits and cityscapes. But as Jason Meisner of the Chicago Tribune reported yesterday, we now know A LOT more about Charles and the paternal side of Maier’s family thanks to Ann Marks. Marks is a former executive with Dow Jones and an amateur genealogist. Ann Marks sifted through documents online several hours a day for months to make her discoveries, and they could have a major impact on who gets any dough associated with Vivian Maier’s work. She joins us. We’re also joined by John Maloof, owner of many of Vivian Maier’s negatives. If you saw the film “Finding Vivian Maier,” which John wrote, directed and produced, you’ll remember that he was the one who discovered Maier’s amazing body of work at an auction on the Northwest Side of Chicago. Before his discovery, few if any people had ever seen her work. Since then, critics have hailed her as one of the best American street photographers of the 20th century.(Flickr/COD Newsroom)
