"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."
All Bentley snowflake photographs are in the public domain, and can be found on numerous websites. For more information please see: Wilson Bentley on Wikipedia.
