Nathaniel Shepard Keith (July 14, 1838 – January 27, 1925) was an American manufacturer, chemist, inventor, writer, and electrical engineer. Keith was born in Boston, Massachusetts, and worked in his fathers laboratory. He was instrumental in designing, manufacturing, and installing the original electric lighting and power system in San Francisco, California. In 1884 he became editor of Electric World, co-founded the American Institute of Electrical Engineers (AIEE) and served as the first secretary of the organization. The AIEE merged with other societies in 1963 to become the IEEE, the Institute of Electrical and Electronics Engineers.
