Excerpt from Men of Science and Industry: A Guide to the Biographies of Scientists, Engineers, Inventors and Physicians, in the Carnegie Library of Pittsburgh Although the material relating to the lives of scientists and engineers is considerable in quantity, it is widely scattered and difficult of access. This condition was recognized many years ago by the Society for the Promotion of Engineering Education, which appointed a committee of investigation, but as yet no feasible plan for a uniform editing of the material has been found. In the mean time, this Library has compiled a card index to the biographies in its own collection, and this bibliography is now printed in the hope that it may prove useful to others, even though it is confined to the resources of one library. The list is, in general, limited to men whose work is con cerned with the subjects represented in the classes Science and Useful Arts, of the Decimal Classification. On this basis some men prominent in business, engineering and invention are in cluded whose rank as scientific workers may be questioned. The limitation to one collection, and that not one attempting completeness, will account for the absence of certain nameswhich might, reasonably be expected to appear. The brief characterizations attached to the names have sometimes given difficulty because of the varied aspects of some men's work, but the endeavor has been to choose the field in which each has made his most important contributions to science. A man's birthplace has been considered as determining his nationality. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
