Although prominent in the educational field, Louis Duncan was best known as an electrical traction expert and consulting engineer.

Doctor Duncan was born in Washington DC, March 25, 1861, and graduated from the United States Naval Academy in 1880. For about 6 years of service after graduation, he was assigned part of the time to special duty at the John Hopkins University, to assist in determining the absolute unit of electrical resistance. For this work he received the Ph.D. degree from the university in 1885. In 1886 he resigned from the Navy and joined the teaching staff of John Hopkins, where he was in charge of a course in electrical engineering for 14 years. He inspired much original work on the part of his students.

At the same time he was occupied with various electrical engineering problems and was engineer in charge of construction of a number of electric roads in Baltimore, consulting engineer for many of the electric roads in Washington, chief engineer and in charge of construction of the Third Avenue System in New York, engineer for the Baltimore and Ohio Company, equipping the Baltimore tunnel with electric locomotives, and was a consultant for a number of other railroad and lighting concerns.

In 1899, he resigned his position at the University and devoted his entire time to his consulting practice, organizing the firm of Sprague, Duncan and Hutchinson, but in 1902 when the Massachusetts Institute of Technology built a new electrical laboratory and separated the course of electrical engineering from the physics department, he was called upon to inaugurate the course, and the idea had such an appeal to him that he accepted and donned the professorial robes again for 2 years, as head of the electrical engineering department. He then returned to his practice and was active as a consulting engineer until his death, February 13, 1916.

He took out several patents on devices for electrical machines, as well as patents on secondary batteries.

He did important consulting work for numerous utilities, including the Cincinnati Traction Company, the Indianapolis Traction Company, and many of the railroad companies in the Middle West. He was consulting engineer for the Rapid Transit Commission of New York City, chief engineer of the Keystone Telephone Company of Philadelphia, and of the independent telephone systems at Baltimore and Pittsburgh.
