One of the first people to record images of snow crystals and discover that the designs were never duplicated was Wilson A. Bentley (1865–1931) of Vermont, who became known as "Snowflake Bentley." Through the use of a microscope and camera, known as "photomicrography", he was able to take detailed images of individual snowflakes before they disappeared.
