Vivian Maier’s profession was a nanny in Chicago. However, she was a prolific street photographer who captured images of everyday life for more than 50 years. During this period she accumulated more than 100,000 negatives and undeveloped rolls of film which she warehoused in a storage facility. After her death in 2009 at the age of 83, the contents of her storage locker were auctioned to recover the cost of delinquent rent. John Maloof, a filmmaker and photographer, purchased a box from the lot and became a champion of her work, later purchasing the remaining collection.
