Bentley, W.A. and Humphreys, W.J.
Snow Crystals, 1931
1677

In 1931 Dr. William J. Humphreys, Chief Physicist for the U.S. Weather Bureau, sorted through some 4500 of Bentley's photomicrographs (the original negatives and some of his notebooks are housed at the Jericho Historical Society, Vermont) and published 2453 of his pictures -- most of them of ice crystals and about 100 of sleet , ice, frost and dew. By adapting a microscope to a bellows camera, Bently became the first person to photograph a single snow crystal in 1885. His work showed that no two snowflakes are alike.
