Amateur street photographer and nanny Vivian Maier took around 100,000 photographs in her lifetime, leaving behind over 700 roles of undeveloped color film, reels of 8 mm and 16 mm movies, and audiotape interviews shot on the streets of Chicago. In 2007, local historian John Maloof purchased a box of 30,000 prints and negatives from the unknown shutterbug in an auction house and realized he had stumbled upon something incredible. Since Maloof's discovery, Maier's work has been exhibited internationally — she never revealed her photography to a soul prior — and Maloof (with Charlie Siskel) has created a documentary about the reclusive artist called Finding Vivian Maier.
The below trailer contains snippets of interviews with the now-grown children that Maier cared for. They describe venturing into "dangerous" neighborhoods so their mysterious nanny could snap pictures. "I'm sort of a spy," Maier was said to tell acquaintances. As Maier's collection of boxes filled with private work grew, things seemed to get stranger, but her documentation of 1950s and '60s Chicago tells the story of a sensitive and keenly observant artist truly ahead of her time. Check out some of Maier's work below, and look for Maloof's documentary in 2014. [via Colossal]
