Louis Bell (December 5, 1864 to June 14, 1923) was an American engineer, physicist, inventor, and academic. He was an early pioneer in illumination engineering and the transmission of electricity, [1] being awarded 25 patents in power transmission. [2]
Louis Bell was born December 5, 1864, in the small village of Chester, New Hampshire, the youngest child of Louis Bell (Sr.) and Mary Anne (Mollie) Persis Bouton. His father was a New Hampshire lawyer who died in 1865 while serving as a Union Army colonel at the battle of Fort Fisher during the American Civil War. [5] [6] His mother died shortly thereafter, leaving Louis Bell and his older sister Marion [7] to be raised by their grandmother, Lucy G. Bell née Smith, [8] the widow of prominent New Hampshire politician Samuel Bell. [9]
An intelligent boy, Bell was an avid reader, and his studies were encouraged by his grandmother. [2] At the age of ten he attended the nearby Northwood Academy. [10] Two years later, Bell was sent to be educated at Phillips Exeter Academy, and he matriculated to Dartmouth College in 1880. [8] There he studied physics and chemistry, among other subjects, while taking an interest in astronomy. He graduated with an A.B. in 1884, after winning final honors in physics, honorable mention in English, and serving as associate editor of The Dartmouth . [8] [10]
After remaining a year at Dartmouth as a post-graduate, he spent three years in residence at Johns Hopkins University studying physics and chemistry under Henry A. Rowland. [2] [8] Bell was awarded a Ph.D. in 1888 with a thesis titled On the Absolute Wave-length of Light. [3] He next joined the staff of Purdue University as a professor seated in the newly established chair of applied electricity. While there he organized the instruction as head of the newly founded school of electrical engineering. Resigning at the end of the year, he joined the consulting firm of Bliss and Bell. [10] In 1890, he became editor of Electrical World , a weekly journal owned by the W. J. Johnston company. Bell would maintain a literary connection with the publication for the remainder of this life. [2]
In 1892, he was hired as chief engineer for the power transmission department of the General Electric company. Bell would design some of the nation's first polyphase power transmission plants. The same year, he published The Electric Railway in collaboration with Oscar T. Crosby. During 1893, he supervised the installation of the nation's first three-phase generators at the Redlands Power Plant in Mill Creek, California. [11] He went on to work on the Folsom Powerhouse, which became the most powerful in the world at that time. Using a system Bell designed, this generator transmitted a now-standard 60 Hz frequency alternating current over long-distance lines, 35 miles (56 km) to Sacramento in 1895. It was the first facility in the nation to do this. [12]
He married Sarah Gross Hemenway in 1893. [2] Sarah was a Dartmouth alumni from the class of 1884. [13] They would have one son, Louis Hemenway Bell. [2]
Bell became a Boston engineering consultant in 1895, and he remained in this job for the rest of his life. Initially his focus was on power transmission, but later he specialized in the engineering of illumination. He lectured at both Harvard and the Massachusetts Institute of Technology. [2] In 1897, he authored Electric Power Transmission, which became a standard textbook on the subject for several years. [1] During the Spanish–American War (1898), Bell served as a technical officer in the Volunteer Electrical Corps. [2]
His Art of Illumination was published in 1902 and became a standard work on the topic. He contributed articles on electric power transmission and electric motors to the 10th and 11th editions of Encyclopædia Britannica. [1] In 1908, Bell served as the third president of the Illuminating Engineering Society. [14] During World War I, he was a member of the advisory committee for the Council of National Defense. For a period of ten years he served as vice president of the Illuminating Engineering Society of Great Britain. During the early days of the automobile, he worked on headlights and the development of headlight lenses. [2]
Bell retained an interest in astronomy for much of his life, and in 1922 he authored The Telescope. He was known to be a good shot and had a life-long love of the outdoors. He died June 14, 1923. An honorary Doctorate of Science was awarded to him by Dartmouth College shortly after his death. [15]
Charles Proteus Steinmetz was an American mathematician and electrical engineer and professor at Union College. He fostered the development of alternating current that made possible the expansion of the electric power industry in the United States, formulating mathematical theories for engineers. He made ground-breaking discoveries in the understanding of hysteresis that enabled engineers to design better electromagnetic apparatus equipment, especially electric motors for use in industry.
Isadore Manuel Singer was an American mathematician. He was an Emeritus Institute Professor in the Department of Mathematics at the Massachusetts Institute of Technology and a Professor Emeritus of Mathematics at the University of California, Berkeley.
Arthur Edwin Kennelly was an American electrical engineer.
Sir Joseph Larmor was an Irish and British physicist and mathematician who made breakthroughs in the understanding of electricity, dynamics, thermodynamics, and the electron theory of matter. His most influential work was Aether and Matter, a theoretical physics book published in 1900.
Henry Augustus Rowland was an American physicist and Johns Hopkins educator. Between 1899 and 1901 he served as the first president of the American Physical Society. He is remembered for the high quality of the diffraction gratings he made and for the work he did with them on the solar spectrum.
Laurence Monroe Klauber, was an American herpetologist and the foremost authority on rattlesnakes. He was the first curator of reptiles and amphibians at the San Diego Natural History Museum and Consulting Curator of Reptiles for the San Diego Zoo. He was also a businessman, inventor, and contributed to mathematics in his study of the distribution of prime numbers.

John James Stevenson was an American geologist, born in New York City. He graduated from New York University in 1863, became professor of chemistry at West Virginia University for two years (1869–71), then served as professor of geology at New York University until 1909. During 1873–74 and from 1878 to 1880 he was geologist for the United States Geological Survey. He also served on the Pennsylvania Geological Survey from 1875 to 1878 and from 1881 to 1882. He was president of the Geological Society of America in 1898.

Albert Kingsbury was an American engineer, inventor and entrepreneur. He was responsible for over fifty patents obtained between the years 1902 to 1930. Kingsbury is most famous for his hydrodynamic thrust bearing which uses a thin film of oil to support weights of up to 220 tons. This bearing extended the service life of many types of machinery during the early 20th century. It was primarily outfitted on Navy ships during World War I and World War II.
William Grylls Adams was professor of Natural Philosophy at King's College, London. He was active in research on subjects ranging from light, magnetism, and astronomy to electrical power generation and transmission. His research in optics yielded the discovery that certain materials, notably selenium, produce an electric current when exposed to light. Adams also actively participated in many academic societies and held major positions within the societies.
