Document Title: Walter Orr Roberts and the Climax coronagraph, circa 1945 (DI02072)
Description: Walter Orr Roberts is shown taking photos of the solar corona with the 5-inch coronagraph he built with the assistance of Hobart P. French and his Harvard Ph.D. advisor Donald Howard Menzel. This, only the third coronagraph in the world and the first in the Western Hemisphere, was made possible by Don Menzel's entrepreneurial skills and Robert's technical capabilities. Roberts and his wife Janet began their six-year residency at "The Fremont Pass Station of the Harvard College Observatory" in Climax, Colorado on August 15, 1940. It was here that Roberts discovered the link between solar flares and radio interference, and during World War II the military used the information he gathered to ensure uninterrupted communications.
