Born on December 6th:

Nicolas LEBLANC (1742 - 16.1.1806), a French chemist-technologist who developed the first industrial method for producing soda from table salt, and received a prize from the French Academy of Sciences for this development. He later built a plant that produced 320 tons of soda ash per year. Nowadays, instead of this process, a profitable and convenient ammonia-soda process is used.

Joseph Louis GAY-LUSSAC (1778 - 9.5.1850), a French physicist and chemist. The main studies of the scientist are associated with the study of the properties of gases. For scientific purposes, he made two balloon flights, reaching 7016 m during the second altitude. Gay-Lussac introduced the name “chlorine”, and for the first time received pure hydrocyanic acid. He invented a number of devices - a hydrometer, an alcohol meter, a barometer, thermometers, and a pump.

Nikolai Semenovich KURNAKOV (1860 - 19.3.1941), a physic chemist, an academician (1913), the founder and first director of the Institute of Physicochemical Analysis of the USSR Academy of Sciences, first director of the State Institute of Applied Chemistry, the head of the Institute for the Study of Platinum and Other Noble Metals of the USSR Academy of Sciences, director Institute of General and Inorganic Chemistry, Academy of Sciences of the USSR, which since 1944 bears his name.

Charles Martin HALL (1863 – 27.12.1914), an American chemical engineer. He conducted experiments on the release of aluminum by electrolysis of cryolite-alumina melt. Received by electrolysis the first aluminum. A little later, C.M. Hall received a patent for an electrolytic method for producing aluminum. In total, he received 22 patents, one way or another connected with aluminum. He was awarded the Perkin Medal for achievements in the field of applied chemistry (1911).

George Eugene UHLENBECK (1900 – 31.3.1988), an American theoretical physicist of Dutch origin. His scientific works relate mainly to quantum mechanics, atomic and nuclear physics, kinetic theory, statistical mechanics, nonlocal quantum field theory. He gained the greatest fame thanks to the discovery of the electron spin, made together with Samuel Goudsmit.

George PORTER (1920 - 31.8.2002), an English chemist, the Nobel laureate of 1967 "for their studies of extremely fast chemical reactions, effected by disturbing the equilibrium by means of very short pulses of energy" (together with Ronald NORRISH and Manfred EIGEN). A half (in monetary terms) was given to the British laureates, the second part - to Eigen.

Mikhail Grigorievich VORONKOV (1921 - 10.2.2014), an organic chemist, an academician (1990). One of the founders of organ silicon chemistry. The main studies of the scientist were associated with the chemistry of organic silicon compounds. For the first time in the world, he began a systematic study of heterolytic cleavage reactions of the Si-O-Si group. He conducted research in the field of chemistry, physical chemistry, biology and pharmacology of silatranes, as well as other compounds of hypervalent silicon. Under his leadership, a number of original medicines were created that have no analogues in world medicine.

Yanush Bronislavovich DANILEVICH (1931 - 15.5.2011), a specialist in the field of energy and electrical engineering, academician of the Russian Academy of Sciences (1997), who advocated the development of alternative energy. He is known as the author and leader of fundamental scientific works in the fields of theoretical and experimental analysis of electromagnetic fields in electric machines, the study of anomalous modes and transients in high-power electric machines, the creation of superconducting energy converters, alternative energy, and energy-saving systems.
