In the age of blogs and self-proclaimed street photography, the collected works of a children's nanny might not sound like much. But Vivian Maier (above), was a Chicago nanny who, throughout the 20th century, secretly amassed thousands of prints, hundreds of undeveloped rolls, home movies, and audio interviews. Although no one seems to have known of her considerable talent while she was alive, Maier was an incredible street photographer and collector of strangers and their stories. Her former charges, now well into adulthood, remember that she took them along on expeditions to capture the world outside, although she never revealed how in-depth her work had gotten.
In 2007, the 26 year-old John Maloof uncovered Maier's collected works at an auction house, and paid $380 for a box of prints. Since then, Vivian's presence in the art world has loomed quite large, and her story is being told in a documentary called Finding Vivian Maier. It is expected to be released later in 2013.
