Ten of the pioneering photos of snowflake crystals that American farmer Wilson Bentley began taking more than a century ago are to be sold in New York.

Wilson A Bentley (1865-1931) is thought to be the first photographer to capture images of single snowflakes on camera. He made thousands of the jewel-like prints, and came to the conclusion that no two snowflakes were the same. This concept caught the public imagination and he published other articles in magazines, including National Geographic, Nature (Journal), Popular Science and the Scientific American. His photographs have been requested by academic institutions worldwide. Bentley poetically described snowflakes as “tiny miracles of beauty” and snow crystals as “ice flowers.”

His photomicrography technique involved a microscope and a bellows camera. Snowflake expert Kenneth Libbrecht said the photos did not meet modern standards because of the “crude equipment” Bentley used.

“But he did it so well that hardly anybody bothered to photograph snowflakes for almost 100 years,” Mr Libbrecht added. He perfected a process of catching flakes on black velvet in such a way that their images could be captured before they melted.

Ironically, Bentley caught pneumonia in a blizzard and died just weeks after the publication of his book Snow Crystals.

Chicago art gallery owner Carl Hammer is selling them along with 16 of Bentley’s winter scenes at an antiques show at New York’s American Folk Art Museum.

“They’re remarkably beautiful,” said Mr Hammer.

“There are imperfections on the outer edges of the image itself and on the paper, but the images themselves are quite spectacular.”

Bentley, who was known as The Snowflake Man, wrote in 1925: “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.”

Bentley also photographed all forms of ice and natural water formations including clouds and fog. He was the first American to record raindrop sizes and was one of the first cloud physicists.
