Vivian Dorothea Maier worked for around forty years as a nanny in Chicago. In her time off she took photographs, totalling over 150,000. These were left in unmarked storage boxes, undeveloped and undiscovered until after her death in 2009 when John Maloof, Chicago historian got hold of them and started publishing scans of the pictures on the internet.
She is now known as one of the 20th century's best photographers. Finding Vivian Maier is a documentary about the life and works of the daytime nanny and closet photography genius.
