Japanese physicist Ukichiro Nakaya (1900-1962) produced the first artificial snow crystal on the tip of a single rabbit hair in 1936. Nakaya began researching snow crystals in the early 1930s at Hokkaido University. By taking over 3,000 photographs, he established a classification of natural snow crystals and described their relationships with weather conditions. His work still remains a primary reference on crystal shapes. "Snowflakes are letters sent from heaven," he wrote in his book "Snow Crystals: Natural and Artificial."
