An incredible story. Vivian Maier was a nanny who lived in Chicago for most of her life and passed away in 2009 at the age of 83. Little more is known about her, except that she was an avid street photographer. Her work was discovered at an auction in 2007, more than 100,000 negatives and undeveloped rolls of film, sold by a storage facility who were cleaning out her locker for delinquent rent.
