Louis Bell

Louis Bell (born December 5, 1864 in Chester , New Hampshire , † June 14, 1923 in West Newton , Massachusetts ) was an American physicist.

After his father died in the Civil War and his mother died shortly afterwards, Bell grew up with his grandmother in Chester, New Hampshire. He attended Philips Exeter Academy, and graduated from Dartmouth College in 1884 . He then spent three years at Johns Hopkins University under Henry Augustus Rowland , where he carried out spectroscopic studies with the latter's diffraction gratings and worked on the atlas of absorption lines. When Michelson had developed his interferometer technology , the measurement with the diffraction gratings became obsolete and so he went to Purdue University for a year in 1888 , where he studied electrical engineering. Two years later he was the author of Electrical World . In 1893 he was General Electric's chief engineer of the power transmission department and installed the first three-phase transmission in Redlands, California . After 1895 he worked in Boston as a consulting electrical engineer. He was a member and president of the Illuminating Engineering Society and was associated with the Harvard College Observatory . He was friends with Gordon Ferrie Hull . In 1905 he was elected to the American Academy of Arts and Sciences . During the First World War he was involved in research on the periscope with Carl Axel Robert Lundin , and continued this with the optician Walter Wolfe from Boston. In 1921 he published Ghosts and Oculars on ghost images as a result of reflections in optical systems such as the waiter's ocular. He held over 40 US patents.
