Let me introduce you to Vivian Maier. Vivian worked as a nanny for most of the 1950's through the rest of her life, but secretly, she was a street photographer. She rarely shared her photographs.
In 2007 John Maloof discovered a trunk full of negatives at a local thrift auction house on Chicago's Northwest Side. Vivian Maier had come to light. I have put some pictures here, but I urge you to take a look at the Vivian Maier website; it's fascinating. These photographs would make good story starters.
