23 Feb 1938 Bronx High School of Science	science	Bronx High School of Science In 1938, the Bronx High School of Science was voted by the Board of Education to be established by repurposing an existing school building in the Bronx at 184th St. and Creston Ave. It opened in Sep 1938, the first of its kind in New York City. A report by the Board of Superintendents had recommended creating an instiution to develop a scientific way of thinking, with science courses to train prospective physicians, dentists, engineers and laboratory workers. Using entrance exams to screen for suitable ability, about 400 boys were admitted upon opening, and more in subsequent years to a full enrollment of about 2,500. The building was remodelled with laboratories and other facilities including an auditorium equipped for demonstrations to the entire student body. From the outset, it was questioned why girls were not admitted, but it became co-ed in 1946. Its graduates include several Nobel Prize winners.

03 Jul 1938 Fastest steam locomotive	science	Fastest steam locomotive In 1938, the Mallard was documented as the world's fastest steam locomotive travelling at 126 mph (202-km/h) at milepost 90¼, on straight, slightly downhill tracks, between Little Bytham and Essendine, on the East Coast Main line of the London and North Eastern Railway, in England. It was hauling six coaches and a dynamometer car recording the speed, with a total tare of 240 tons. The Mallard was designed as a streamlined express locomotive with an aerodynamic body, 70-ft long, weighing 165 tons with tender. Its build date was 3 Mar 1938, and it was used in service until it was retired 1963. After restoration in the 1980's it made a few special runs, and is now in the National Railway Museum, York.
20 Sep 1938 patents	science	patents (chemistry) The first patents for nylon (first synthesized in 1935) are granted in the name of Wallace Carothers to DuPont. The first items produced in the new material are toothbrush bristles.
26 Sep 1938 Alan Andrew Watson	science	birth Alan Andrew Watson Alan Andrew Watson, Scottish astrophysicist
11 Oct 1938 Glass wool	science	Glass wool In 1938, R. Games Slayter (died 15 Oct 1964) and John H. Thomas patent glass wool and the machinery to make it. Games Slayter, the driving force behind Owens Corning technology and innovation, sought to make a finer glass fiber material. In 1932, Dale Kleist, a young researcher under Jack Thomas (Slayter's research assistant), working on an unrelated experiment accidentally caused a jet of compressed air to strike a stream of molten glass, resulting in fine glass fibers. By Fall 1932, Kleist refined the process by using steam, to make glass fiber material thin enough for commercial fiber glass insulation. From March 1933, Games Slayter directed Jack Thomas in experiments using glass wool, instead of natural or other synthetic fibers, on textile machinery.
16 Nov 1938 Lysergic acid diethylamide	science	Lysergic acid diethylamide (chemistry) Lysergic acid diethylamide is first synthesized by Albert Hofmann from ergotamine at the Sandoz Laboratories in Basel.
20 Nov 1938 Edwin Hall	science	death Edwin Hall Edwin Hall, American physicist, discoverer of the "Hall effect" (b. 1855)
22 Dec 1938 First coelacanth discovered	science	First coelacanth discovered In 1938, a coelacanth, a primitive fish thought extinct, was discovered. Marjorie Courtenay-Latimer was curator of the museum in the port town of East London, northeast of Cape Town, South Africa, and always interested in seeing unusual specimens. Hendrik Goosen, captain of the trawler Nerine, called her to see his catch of the day before, made at about 70-m depth, off the Chalumna River southwest of East London. She spotted an unusual 5-ft fish in his "trash" fish pile. It was pale mauvy-blue with iridescent silver markings. She sent a sketch to Dr J.L.B. Smith, a senior lecturer in chemistry from Rhodes University in Grahamstown for identification. It was hailed as the zoological discovery of the century and equated to finding a living dinosaur!
22 Dec 1938 Marjorie Courtenay-Latimer	science	Marjorie Courtenay-Latimer (biology) Marjorie Courtenay-Latimer discovers a Coelacanth, formerly seen only in fossils millions of years old, in a fisherman's catch in South Africa.
