In the 1940s, GE and government researchers were trying to figure out how to weaken the destructive power of hurricanes. Part of that work involved building an understanding of how ice crystals form in clouds. These animations come from a 1947 film showing scientists making snow in a lab freezer.
GE scientists including Nobel Prize winner Irving Langmuir, Vincent Schaefer and Bernard Vonnegut studied the science of snow. Their experiments with weather control provided Bernard’s brother, Kurt, the inspiration to write Cat’s Cradle.
