[1] He perfected a process of catching flakes on black velvet in such a way that their images could be captured before they either melted or sublimated, and elaborated the theory that no two snowflakes are alike.

Bentley donated his collection of original glass-plate photomicrographs of snow crystals to the Buffalo Museum of Science.

[7] In collaboration with George Henry Perkins, professor of natural history at the University of Vermont, Bentley published an article in which he argued that no two snow crystals were alike.

This concept caught the public imagination and he published other articles in magazines, including National Geographic, Nature, Popular Science, and Scientific American.

[8] Bentley also photographed all forms of ice and natural water formations including clouds and fog.

[11] At the Fairbanks Museum and Planetarium, a meteorological observation center in St. Johnsbury, Vermont, there is an exhibit about atmospheric ice crystal formation featuring several of Bentley’s photos and a short biography.
