Jan. 21, 2011 -- No two snowflakes are alike -- but how do we know this? Well, the answer comes from Wilson A. Bentley's late-19th century photomicrography of snowflakes.
A Vermont farmer, Bentley became fascinated by the crystalline structure of snowflakes as a child and began experimenting with trying to capture the singular shape of a snowflake under a microscope with a bellows camera -- the contraptions with a folding box of pleated material between the lens and film.
"Under the microscope, I found that snowflakes were miracles of beauty; and it seemed a shame that this beauty should not be seen and appreciated by others. Every crystal was a masterpiece of design and no one design was ever repeated. When a snowflake melted, that design was forever lost. Just that much beauty was gone, without leaving any record behind," Bentley is quoted by the Jericho Historical Society.
Snowflakes' Shape Changed by Pollution
During a snowstorm on Jan. 15, 1885, Bentley became the first person to ever photograph a single snowflake.
Although it took years for Bentley to establish a process to photograph snowflakes, once he mastered it, his only complaint was the cold.
"The photographing of snowflakes, although quite delicate work, can hardly be called difficult, although some hardships attend it, because the work must all be done in a temperature below freezing, and under conditions of much physical exposure,” Bentley wrote in a 1922 article for Popular Mechanics Magazine.
