Rufus Henry Gilbert

Died 10 Jul 1885 at age 53 (born 26 Jan 1832).U.S. surgeon and inventor who played a major role in the development of rapid transit in New York City. After serving as a surgeon in the Federal Army in the Civil War, he became interested in rapid transit as a means of freeing people from living in the unhealthful, crowded tenements in the centres of large cities. Gilbert obtained two patents in 1870 on a pneumatic-tube system, and he incorporated the Gilbert Electric Railway Company on 17 Jun 1872, to build elevated lines in New York City. The cars were to be propelled by air pressure from pneumatic tubes mounted on the elevated structure. A financial depression delayed construction until 1876, and forced adoption of a conventional track with trains drawn by steam locomotives, which opened 6 Jun 1878.
