23 Feb 1893 Diesel engine patent	science	Diesel engine patent In 1893, Rudolf Diesel received a German patent for the diesel engine. His engine burns fuel oil rather than gasoline, and uses high compressed of the gases in the cylinder rather than a spark to ignite the fuel. Diesel engines were used widely in Europe for their efficiency and power, and are still used today in most heavy industrial machinery. Diesel cars never caught on in the U.S., partly because the diesel engine's greater efficiency is counter-balanced by its higher emissions of soot, odor, and air pollutants. However, some environmentalists argue that in spite of the diesel engine's exhaust pollution, its fuel efficiency may make it more environmentally sound than the gasoline engine in the long run.

27 Feb 1893 Ralph Linton	science	birth Ralph Linton Born 27 Feb 1893; died 24 Dec 1953 at age 60. American anthropologist who had a marked influence on the development of cultural anthropology. After combat in France during World War I, he received a Ph.D. from Harvard (1925). In the early 1920's he did fieldwork in Polynesia. He introduced the terms "status" and "role" to social science and influenced the development of the culture-and-personality school of anthropology. His works, such as The Study of Man (1936) and The Tree of Culture (1955), are regarded more as popularizations of anthropology than as original scholarship.
28 Feb 1893 Carborundum	science	Carborundum In 1893, carborundum was patented by Edward G. Acheson of Monongahela, Penn. He had discovered it accidentally while trying to make artificial diamonds. He had dissolved carbon into molten corundum (a mixture of powdered coke and clay) in an electric furnace, and that yielded dark, hard, gritty crystals. He named the new material carborundum, and found it was one of the hardest industrial substances (second only to diamond), which made it an excellent abrasive material. In 1894, he started the Carborundum Company in Monongahela to produce grindstones, knife sharpeners, and various abrasives. Later, on 19 May 1896, obtained a patent for an electric furnace, suitable for making carborundum.
28 Feb 1893 Edward Goodrich Acheson	science	Edward Goodrich Acheson (technology) Edward Goodrich Acheson patents the method for making the abrasive silicon carbide powder.

His other designs include the Baby (a truly light aircraft), Avian, and the Anson (used for RAF coastal reconnaissance). In WW II, he developed the Manchester and the famous Lancaster heavy bombers. Later, he worked jet-propelled planes, the Tudor and Ashton. He died in a test flight crash of the Tudor II prototype, near Woodford airfield, Manchester.

15 Aug 1893 Leslie Comrie	science	birth Leslie Comrie Born 15 Aug 1893; died 11 Dec 1950 at age 57. Leslie (John) Comrie was a New Zealand astronomer and pioneer in the application of punched-card machinery to astronomical calculations. He joined HM Nautical Almanac Office (1926-36), where he replaced the use of logarithm tables with desk calculators and punched card machines for the production of astronomical and mathematical tables. This made scientific use of these machines, made originally for only business uses. In 1938, he founded the Scientific Computing Service Ltd., the first commercial calculating service in Great Britain, to further his ideas of mechanical computation for the preparation of mathematical tables. His use of card processing systems prepared the way for electronic computers.

13 Nov 1893 Edward A. Doisy	science	birth Edward A. Doisy Born 13 Nov 1893; died 23 Oct 1986 at age 92. Edward Adelbert Doisy was an American biochemist who shared (with Henrik Dam) the 1943 Nobel Prize for Physiology or Medicine for his isolation and synthesis of vitamin K, a substance that encourages blood clotting (1939), used in medicine and surgery. With the embryologist Edgar Allen (1922-34), he developed assay techniques that facilitated research on sex hormones. Doisy and his associates isolated the sex hormones estrone (theelin, 1929; the first estrogen to be crystallized), estriol (theelol, 1930), and estradiol (dihydrotheelin, 1935). In 1936-39 he isolated two forms of the vitamin, (K1 from lucerne seed and K2 from fish meal, in a pure crystalline form), determined their chemical structures, and synthesized the vitamin.

12 Dec 1893 Aerial photography	science	Aerial photography In 1893, the first U.S. patent for aerial photography was issued to Cornele B. Adams of Augusta, Ga. (No. 510,758). His method of photogrammetry could produce a topographic map by means of photos of the same tract taken from different points. The patent refers to aerial photographs taken automatically at a predetermined height from an unmanned stationary balloon on a tether rope at each end of a measured base line on the land. "The pictures obtained can be converted into topographic maps, to delineate not only the horizontal positions and distances of the objects correctly, but from which the altitude of the objects can be quickly and accurately ascertained, and such results obtained without the aid of other field instruments."
