Prof. H. A. Bumstead

J. J. T.


THE death of Prof. H. A. Bumstead, professor of physics in Yale University, which occurred with tragic suddenness on January 1 when he was travelling from Chicago to Washington, will be felt with the keenest regret by a large number of men of science in this country. There are few American men of science with more English I friends than had Prof. Bumstead, and none whose I friendship and companionship were more highly prized. Born in 1870, he graduated at Johns Hopkins in 1891. He began in 1893, as instructor in physics in Sheffield Science School, that connection with Yale which continued without interruption until his death, where, for fourteen years, he had been professor of physics and director of the Sloane Physical Laboratory. Prof. Bumstead was the most enthusiastic and devoted of Yale men. He came over to Cambridge in 1904, and worked for a year at the Cavendish Laboratory; the result of his work is contained in a paper in the Philosophical Magazine for June, 1906, p. 292, on the heating effects produced by Rontgen rays in different metals. On his return to America he made, in spite of serious ill-health, important researches on the properties of α-rays.
