Vivian Maier was one of the greatest American street photographer. When she was a nanny, she took over 100,000 images, especially in Chicago. However, she never talked about her work when she was alive and became famous for it after she died. When her work was discovered in 2007 there were over 100,000 negatives and many hundreds of rolls of unprocessed film in the collection. John Maloof began to scan and collate her work and shared some of it on a blog and later a website dedicated to the project.
She took impressive photographies that depict street scenes in Chicago and New York, in the 1950s and 1960s.
