The discovery that rocked the art world.

When John Maloof bought an unmarked box of undeveloped negatives back in 2007, he had no idea that he had just stumbled upon one of the 20th Centurys most important troves of street photography and self/portraiture. The photographer: Vivian Maier, a secretive and eccentric nanny who over the course of more than three decades took tens of thousands of photos of everydayurban life - and showed them to no one. Finding Vivian Maier follows Maloof as he embarks on a quest to reveal the woman behind the Rolleiflex camera. Part retrospective, part detective story,Finding Vivian Maier is a touching portrait of a woman haunted by her past. For a contemporary age obsessed with self-documentation via all forms of technology, Vivian Maier was a pioneer.
