Karl Christian Friedrich Pfizer (German: [kaʁl ˈpfɪtsɐ]; March 22, 1824 – October 19, 1906), known as Charles Pfizer, was a German-American businessman and chemist who co-founded the Pfizer pharmaceutical company with his cousin, Charles F. Erhart, in 1849, as Chas. Pfizer & Co. Inc.
Eugen Baumann (12 December 1846 – 3 November 1896) was a German chemist. He was one of the first people to create polyvinyl chloride (PVC), and, together with Carl Schotten, he discovered the Schotten-Baumann reaction.
Fritz Georg Arndt (6 July 1885 – 8 December 1969) was a German chemist recognised for his contributions to synthetic methodology, who together with Bernd Eistert discovered the Arndt-Eistert synthesis.
Lloyd Viel Berkner (February 1, 1905 in Milwaukee, Wisconsin – June 4, 1967 in Washington, D.C.) was an American physicist and engineer. He was one of the inventors of the measuring device that since has become standard at ionospheric stations because it measures the height and electron density of the ionosphere. The data obtained in the worldwide net of such instruments were important for the developing theory of short wave radio propagation to which Berkner himself gave important contributions.
Berkner was elected to the United States National Academy of Sciences in 1948.Later he investigated the development of the Earth's atmosphere. Since he needed data from the whole world, he proposed the International Geophysical Year in 1950. At that time, the IGY was the largest cooperative study of the Earth ever undertaken.
Berkner was elected a Fellow of the American Academy of Arts and Sciences and a member of the American Philosophical Society in 1956. The IGY was carried out by the International Council of Scientific Unions while he was president in 1957–1959. He was also a member of the President's Scientific Advisory Committee in 1958 while he was president of Associated Universities Inc.
In 1963, Berkner, with L.C. Marshall, advanced a theory to describe the way in which the atmospheres of the Solar System's inner planets had evolved.
Beginning in 1926, as a naval officer, Berkner assisted in the development of radar and navigation systems, naval aircraft electronics engineering, and studies that led to the construction of the Distant Early Warning system, a chain of radar stations designed to give the United States advance warning in the event of a missile attack across the North Pole. In the 50s and 60s, Berkner held intelligence clearances in the Atomic Energy Commission and other agencies. He worked with the CIA in some capacity as well, but any activities are wholly classified as of 2015.Berkner worked with Dallas community leaders to establish the Graduate Research Center of the Southwest (later renamed the Southwest Center for Advanced Studies, which would eventually become The University of Texas at Dallas).He wrote more than 100 papers and several books, including Rockets and Satellites (1958), Science in Space (1961), and The Scientific Age (1964).
In 1961, Berkner was president of the Institute of Radio Engineers.
Emmett W. Chappelle (October 24, 1925 – October 14, 2019) was an American scientist who made valuable contributions in the fields of medicine, philanthropy, food science, and astrochemistry. His achievements led to his induction into the National Inventors Hall of Fame for his work on bioluminescence, in 2007. Being honored as one of the 100 most distinguished African American scientists of the 20th Century, he was also one of the members of the American Chemical Society, the American Society of Biochemistry and Molecular Biology, the American Society of Photobiology, the American Society of Microbiology, and the American Society of Black Chemists.
Charles Paul Émile Hugot (1904–1993), known as Émile Hugot was a sugar technologist, manager of sugar factories and he wrote the standard text on engineering in sugar factories.
Osamu Hayaishi MJA (早石 修, Hayaishi Osamu, January 8, 1920 – December 17, 2015), was a Japanese biochemist, physiologist, and military physician. He discovered Oxygenases at the National Institute of Arthritis and Metabolic Diseases, National Institutes of Health in 1955.Citing his "outstanding and pioneering contributions to biomedical sciences and enzymology," the Wolf Foundation awarded Hayaishi the 1986 Wolf Prize in Medicine "for his discovery of the oxygenase enzymes and elucidation of their structure and biological importance".Hayaishi was President of International Union of Biochemistry and Molecular Biology from 1973 to 1976.
Daniel J. Terra (June 8, 1911 – June 28, 1996) was a scientist, businessman, and art collector. A first-generation Italian-American, Terra earned a chemical engineering degree from Pennsylvania State University in 1931, and founded Lawter Chemicals in Chicago in 1940. The success of his global enterprise enabled him to pursue his cultural interests, assembling an art collection and participating in several Chicago arts institutions.
Sir James Walker FRS FRSE FCS LLD (6 April 1863 – 6 May 1935) was a Scottish chemist.
