In this special talk for Mother's Day, Northwestern professor Pamela Bannos’ discusses her new biography of Vivian Maier, Vivian Maier: A Photographer’s Life and Afterlife. Her book reveals how the story of the nanny savant has blinded us to Maier’s true achievements, as well as her intentions. Bannos contrasts Maier’s life with the mythology that strangers—mostly the men who have profited from her work—have created around her absence.
