Vivian Maier arrived in New York in 1951. She later moved to Chicago and worked as a nanny. In her spare time, she took more than 100,000 photographs. But she didn’t share them with anyone. In 2007, when she was 81 and living in poverty, an auction house sold thousands of her prints and negatives for $400. Since then, her work has been exhibited in the United States and Europe, she’s been the subject of a book and now there’s a documentary, Finding Vivian Maier. Of course, there are websites too, including this one, which has lots of information about her and a wonderful selection of her work. She took this picture of herself in 1953. She died in 2009.
