What is Wilson Bentley famous for?

For over forty years, Wilson “Snowflake” Bentley (1865–1931) photographed thousands of individual snowflakes and perfected the innovative photomicrographic techniques. His photographs and publications provide valuable scientific records of snow crystals and their many types.

Who proved no two snowflakes are alike?

Wilson Bentley prepares to photograph a snowflake using his microscope-bellows camera. Over his life time he took well over 5000 microphotographs of snowflakes and thus discovered that no two snowflakes were alike. Today he is best known for his scientific research and photographic work in the study of snowflakes.

Where did snowflakes originate?

In Missouri in the early 1860s, a “Snowflake” was a person who was opposed to the abolition of slavery—the implication of the name being that such people valued white people over black people. The Snowflakes hoped slavery would survive the country’s civil war, and were contrasted with two other groups.

What color is a snowflake?


What makes snowflakes white? While snowflakes appear white as they fall through the sky, or as they accumulate on the ground as snowfall, they are in fact totally clear. The ice is not transparent like a sheet of glass is, but rather is translucent, meaning light passes through but not directly.

Why do we have snowflakes?

A: A snowflake begins to form when an extremely cold water droplet freezes onto a pollen or dust particle in the sky. This creates an ice crystal. As the ice crystal falls to the ground, water vapor freezes onto the primary crystal, building new crystals – the six arms of the snowflake. That’s the short answer.
