The formation and behavior of snow and ice crystals were a lifelong interest of Schaefer's, and in his time at General Electric he was able to focus on the subject during the World War II years as ice related to the safety of U.S. Air Force planes. Schaefer and Irving Langmuir's interest in that topic grew as a result of their World War II-era contract work with the military, and the experiments they conducted after the war's end led directly to their Project Cirrus contract in 1947—an undertaking so extensive that their work in that area merited its own series in this collection. Much of their foundational work in snow and ice composition and behavior was grounded in observations and experiments conducted on Mount Washington in New Hampshire. Schaefer discovered during this time that ice crystals and snowflakes could be captured and observed using Formvar plastic. Using this method, he documented very specific data about ice and snow before creating some of the first replicas of specific snowflake shapes. The work of Schaefer and his colleagues regarding ice research includes handwritten notes, drawings, charts, photographs, reports, and correspondence specific to ice, snow, and Mount Washington.
