Polaroid - Past

A detailed timeline of the history of the Polaroid company can be found here at Save Polaroid.
Although my project is in relation to instant integral film and thus anything before 1972 is irrelevant this is still quite a helpful history as it dates back to 1929 and Edwin Land's first success in "polarizing light without needing a large crystal of an esoteric mineral. He creates the first synthetic sheet polarizer in 1929 and later files his first patent. Problem solved."
