Timeline of the Development of Chemical Compounds


                                       1937 • German forensic scientist Walter Specht discovers that
                                          blood can act as the catalyst needed to produce chemilu-
                                          minescence with luminol, a compound discovered in the
                                          late 1800s.
                                       1937 • Plexiglas Ò  (made from polymethylmethacrylate) is
                                          exhibited at the World’s Trade Fair in Paris.
                                       1937 • The basic process for making polyurethanes is first
                                          developed by German chemist Otto Bayer.
                                       1937 • The cyclamate family of compounds is discovered by
                                          Michael Sveda, a graduate student at the University of
                                          Illinois.
                                       1938 • Polytetrafluoroethylene is invented by Roy J. Plunkett
                                          by accident at DuPont’s Jackson Laboratory.
                                       1939 • Swiss chemist Paul Hermann Mu ¨ ller finds that DDT is
                                          very effective as an insecticide, which makes it useful in
                                          preventing infectious diseases such as malaria.

                                       1939–1945 • During World War II, the U.S. military finds a
                                          number of uses for nylon, polyurethanes, polystyrene,
                                          percholorates, and silica gel.

                                       Early 1940s • Penicillin is first produced for human use and
                                          is valuable in saving the lives of soldiers wounded in
                                          World War II.
