He was an odd-duck Vermont farmer who invented photomicrography and produced thousands of stunning photographs of snow crystals to prove that no two are alike. He made 10,000 glass photomicrographic plates, upon which he captured the images of individual snow crystals, dew and frost. Over the years, the glass plates deteriorated, however, and the work of Wilson Alwyn Bentley might have been lost forever to researchers and the public, had not a group of graduate students from the University at Buffalo stepped in to save it for posterity.
