Excerpt from History of Electric Light From this beginning the section was expanded to include the whole field of engineering and is designated at present as the Divisions of Mineral and Mechanical Technology. The growth and enlarge ment of the collections has been particularly marked in the fields of mining and mineral industries; mechanical engineering, especially pertaining to the steam engine, internal combustion engine and loco motive naval architecture, and electrical engineering, particularly the development of the telegraph, telephone and the electric light. In the acquisition of objects visualizing the history of electric light the Museum has been rather fortunate, particularly as regards the developments in the United States. Thus mention may be made of the original Patent Office models of the more important dynamos, arc lights and incandescent lights, together with original commercial apparatus after these models a unit of the equipment used in the first commercially successful installation on land of an incandescent lighting system, presented by Joseph E. Hinds in whose engraving establish ment in New York City the installation was made in 1881 and a large series of incandescent lights, mainly originals, visualizing chrono logically the developments of the Edison light from Its inception, pre sented at intervals since the year 1898 by the General Electric Company.
