But she also had a hidden talent was not recognised until after her death in 2009. Maier spent her life wandering the streets of Chicago with a Rolleflex camera strapped to her neck taking remarkable black and white pictures of a different side of the city, and a different side of life in America. Now some 100,000 pictures have been unearthed by John Maloof a real estate agent who bought the negatives as part of a storage locker at a Chicago auction house.
