Vivian Maier (1926-2009) had a talent for seeing. As she walked down the street, she not only avoided bumping into people and objects, she actually saw them in a way most people do not; she saw them in their particularity. We know this because more than 100,000 negatives of photographs she took were somewhat accidentally stumbled upon after her death and now form the basis of two concurrent gallery exhibitions, a photo book and two websites. There was a museum show earlier this year at the Chicago Cultural Center. There will be more. Maier's talent is recognized immediately by those who view her work, something she let no one do in her lifetime.
