About Minor Davis

File:Minor Davis - Portrait small.jpg

Minor Meek Davis was born in North Chatham, Massachusetts in 1858. He was educated at the Coffin School in Nantucket before moving with his family to Nebraska. There, he entered the telegraphic profession as a messenger for Western Union. The family moved again to Washington, D.C., where Davis took jobs as an operator for various telegraph companies. In 1876 he was hired as an operator in Western Union’s main office in New York, where he remained for the next five years. With no college training, he dedicated himself to studying the engineering behind telegraphy. In 1883 he co-authored The Quadruplex with William Maver, Jr. Among the first textbooks on telegraphy, it described the operation of Thomas Edison’s four way telegraph. During the next two years, Davis worked in various telegraph offices in New York before being taken on by Francis Jones, head of the electrical department at United Lines, as his assistant. When Jones became head engineer at the newly formed Postal Telegraph-Cable Company, Davis continued on as his assistant. A prolific inventor, he received several patents for his innovations with distribution circuits. In 1893 he became one of the pioneer members of AIEEE, and was honored among the first class of Fellows in 1912. He was appointed head electrical engineer of the Postal Telegraph-Cable Company in 1907, and retired in 1919.
