Wilson Bentley snowflakes

"Wilson Alwyn "Snowflake" Bentley (February 9, 1865 – December 23, 1931), born in Jericho, Vermont, is one of the first known photographers of snowflakes. He perfected a process of catching flakes on black velvet in such a way that their images could be captured before they either melted or sublimated."
