Charlie Siskel, the co-director of “Finding Vivian Maier,” talked with host John Rabe about making a documentary about a nanny who turned out to be one of the century’s best and most fascinating photographers.

During her life, Maier was also a photographer who shot street scenes and interiors mostly, but went unknown her whole life.

John Maloof — Siskel's co-director — bought her negatives at auction and began scanning the photos. Her work has since taken on a life of its own. "Finding Vivian Maier" is nominated for Best Documentary Feature at this year's Academy Awards.
