Henry Andrews Bumstead (March 12, 1870 – December 31, 1920) was an American physicist who taught at Yale from 1897 to 1920. In 1918 he was scientific attache to the United States embassy in London. In 1920 he was Chairman of the National Research Council.
Henry was a high school student in Decatur, Illinois. In 1887 he went to Johns Hopkins University, initially as a student in a pre-medical program. He studied mathematics with Fabian Franklin and took up an interest in that subject. He studied physics with Henry Augustus Rowland and found his calling there. In 1891 he obtained the bachelor's degree and continued at Johns Hopkins as an assistant in the physics laboratory and a graduate student. He studied thermodynamics, electrostatics, and the electromagnetic theory of light.
Henry Bumstead became an instructor at the Sheffield Scientific School of Yale University in 1893, working with Charles S. Hastings. At the same time he became a student of Willard Gibbs, learning vector analysis and continuing the study of thermodynamics and the electromagnetic theory of light. He was awarded the Ph.D. in 1897, composing a thesis A Comparison of Electrodynamic Theories. Bumstead became an assistant professor in 1900.
In 1905 Bumstead spent a sabbatical year at the Cavendish Laboratory. Performing an experiment suggested by J. J. Thomson, Bumstead examined the effect of X-rays (then called Röntgen rays) when applied to lead and zinc, finding that "twice as much heat is produced in lead compared to zinc".
