Edward Olson Hulburt was born in Vermillion, South Dakota, on October 12, 1890, and died at his home in Easton, Maryland, on October 11, 1982. For 31 years he carried on a distinguished research career at the Naval Research Laboratory. From 1924 to 1949 he was head of the Physical Optics Division; then from 1949 to 1955 he served as the Laboratory's first director of research.
At his passing, Hulburt was perhaps the last of a remarkable generation of scientists who participated in the discovery of the ionosphere and developed much of our earliest understanding of solar terrestrial relationships. The story of those early years of discovery contains Hulburt's most brilliant research.
