Snowflake Bentley by Jacqueline Briggs Martin
From the Publisher
Snowflake Bentley is the story of Wilson Bentley, a farmer born in 1865 in Jericho, Vermont, a small town between Lake Champlain and Mount Mansfield, in the heart of Vermont's "snowbelt." Perhaps it was no accident that Bentley always loved snow more than anything else in the world. When he was fifteen his mother gave him a microscope. When he looked at snowflakes under the microscope he was stunned by their delicate beauty.
He decided he had to share that beauty with others. But he did not know how. And there was no one to teach him. His father and his neighbors thought trying to save snowflakes was foolishness, Bentley was determined. And by the time he died in 1931 he was considered the world's expert on snowflakes.Read more about Wilson A. Bentley, and his work, at the Buffalo Museum of Science's digital library in support of the Bentley Snow Crystal Collection.
