3 Baekeland, Leo Hendrik
[br]b. 14 November 1863 Saint-Martens-Latern, Belgiumd. 23 February 1944 Beacon, New York, USA[br]Belgian/American inventor of the Velox photographic process and the synthetic plastic Bakélite.[br]The son of an illiterate shoemaker, Baekeland was first apprenticed in that trade, but was encouraged by his mother to study, with spectacular results. He won a scholarship to Gand University and graduated in chemistry. Before he was 21 he had achieved his doctorate, and soon afterwards he obtained professorships at Bruges and then at Gand. Baekeland seemed set for a distinguished academic career, but he turned towards the industrial applications of chemistry, especially in photography.Baekeland travelled to New York to further this interest, but his first inventions met with little success so he decided to concentrate on one that seemed to have distinct commercial possibilities. This was a photographic paper that could be developed in artificial light; he called this "gas light" paper Velox, using the less sensitive silver chloride as a light-sensitive agent. It proved to have good properties and was easy to use, at a time of photography's rising popularity. By 1896 the process began to be profitable, and three years later Baekeland disposed of his plant to Eastman Kodak for a handsome sum, said to be $3–4 million. That enabled him to retire from business and set up a laboratory at Yonkers to pursue his own research, including on synthetic resins. Several chemists had earlier obtained resinous products from the reaction between phenol and formaldehyde but had ignored them. By 1907 Baekeland had achieved sufficient control over the reaction to obtain a good thermosetting resin which he called "Bakélite". It showed good electrical insulation and resistance to chemicals, and was unchanged by heat. It could be moulded while plastic and would then set hard on heating, with its only drawback being its brittleness. Bakelite was an immediate success in the electrical industry and Baekeland set up the General Bakelite Company in 1910 to manufacture and market the product. The firm grew steadily, becoming the Bakélite Corporation in 1924, with Baekeland still as active President.[br]Principal Honours and DistinctionsPresident, Electrochemical Society 1909.

4 Sperry, Elmer Ambrose
[br]b. 21 October 1860 Cincinnatus, Cortland County, New York, USAd. 16 June 1930 Brooklyn, New York, USA[br]American entrepreneur who invented the gyrocompass.[br]Sperry was born into a farming community in Cortland County. He received a rudimentary education at the local school, but an interest in mechanical devices was aroused by the agricultural machinery he saw around him. His attendance at the Normal School in Cortland provided a useful theoretical background to his practical knowledge. He emerged in 1880 with an urge to pursue invention in electrical engineering, then a new and growing branch of technology. Within two years he was able to patent and demonstrate his arc lighting system, complete with its own generator, incorporating new methods of regulating its output. The Sperry Electric Light, Motor and Car Brake Company was set up to make and market the system, but it was difficult to keep pace with electric-lighting developments such as the incandescent lamp and alternating current, and the company ceased in 1887 and was replaced by the Sperry Electric Company, which itself was taken over by the General Electric Company.In the 1890s Sperry made useful inventions in electric mining machinery and then in electric street-or tramcars, with his patent electric brake and control system. The patents for the brake were important enough to be bought by General Electric. From 1894 to 1900 he was manufacturing electric motor cars of his own design, and in 1900 he set up a laboratory in Washington, where he pursued various electrochemical processes.In 1896 he began to work on the practical application of the principle of the gyroscope, where Sperry achieved his most notable inventions, the first of which was the gyrostabilizer for ships. The relatively narrow-hulled steamship rolled badly in heavy seas and in 1904 Ernst Otto Schuck, a German naval engineer, and Louis Brennan in England began experiments to correct this; their work stimulated Sperry to develop his own device. In 1908 he patented the active gyrostabilizer, which acted to correct a ship's roll as soon as it started. Three years later the US Navy agreed to try it on a destroyer, the USS Worden. The successful trials of the following year led to widespread adoption. Meanwhile, in 1910, Sperry set up the Sperry Gyroscope Company to extend the application to commercial shipping.At the same time, Sperry was working to apply the gyroscope principle to the ship's compass. The magnetic compass had worked well in wooden ships, but iron hulls and electrical machinery confused it. The great powers' race to build up their navies instigated an urgent search for a solution. In Germany, Anschütz-Kämpfe (1872–1931) in 1903 tested a form of gyrocompass and was encouraged by the authorities to demonstrate the device on the German flagship, the Deutschland. Its success led Sperry to develop his own version: fortunately for him, the US Navy preferred a home-grown product to a German one and gave Sperry all the backing he needed. A successful trial on a destroyer led to widespread acceptance in the US Navy, and Sperry was soon receiving orders from the British Admiralty and the Russian Navy.In the rapidly developing field of aeronautics, automatic stabilization was becoming an urgent need. In 1912 Sperry began work on a gyrostabilizer for aircraft. Two years later he was able to stage a spectacular demonstration of such a device at an air show near Paris.Sperry continued research, development and promotion in military and aviation technology almost to the last. In 1926 he sold the Sperry Gyroscope Company to enable him to devote more time to invention.[br]Principal Honours and DistinctionsJohn Fritz Medal 1927. President, American Society of Mechanical Engineers 1928.BibliographySperry filed over 400 patents, of which two can be singled out: 1908. US patent no. 434,048 (ship gyroscope); 1909. US patent no. 519,533 (ship gyrocompass set).Further ReadingT.P.Hughes, 1971, Elmer Sperry, Inventor and Engineer, Baltimore: Johns Hopkins University Press (a full and well-documented biography, with lists of his patents and published writings).LRD -
