Born on January 26th:

Casimir LEFAUCHEUX (1802 – 8.9.1852), a French gunsmith whose work had a significant impact on the development of small arms and ammunition. He created a unitary hairpin cartridge for small arms, popular in the second half of the 19th century, and samples of weapons for it. Lefaucheux hairpin revolvers became a role model in many countries (Austria-Hungary, Belgium, Germany, Spain, etc.), which created a whole line of hairpin small arms - well-established and inexpensive to manufacture.

John Bates CLARK (1847 – 21.3.1938), an American economist, the founder of the American school of marginalism, an author of the theory of marginal productivity. From 1894-1895 he served as the president of the American Economic Association. He proposed a new approach to the study of political economy in order to approach the exact sciences. Also, Clark divided economic theory into two sections - statics and dynamics (by analogy with theoretical mechanics). He made an important contribution to the "marginalist revolution", supplementing the concept of marginal utility of consumer goods with the theory of marginal productivity of labor and capital.

Vitalii Grigoryevich KHLOPIN (1890 - 10.7.1950), a radiochemist, the participant in the Atomic Project, one of the founders of Soviet radiochemistry and the radium industry. He supervised the creation of the first radium plant in the USSR, together with other scientists in 1921 received the first domestic preparations of radium. Khlopin is an author of works on chemistry and geochemistry of radioactive elements. USSR State Prize (1943, 1946, 1949). Many of his students became not only independent scientific researchers, but also were the creators of their own scientific directions and schools.

Ivan Yakovlevich VALENTIK (1906 – 16.11.1988), a Soviet economist, the Honored Worker of the National Economy of the Karelian ASSR (1966). In 1966-1988 he was a senior researcher, the head of the forestry economics group at the Institute of Economics of the Karelian Scientific Center of the Russian Academy of Sciences. Ivan Yakovlevich is an author of several works, including "Economic problems of the development of the productive forces of the Karelian ASSR" and "Economic foundations for the intensification of forestry in the Karelian ASSR".

Polycarp KUSCH (1911 – 20.3.1993), an American physicist. He worked on methods of magnetic resonance, which manage to very accurately determine the magnetic moment of a particle. Subsequent experiments to determine the magnetic moment of an electron in sodium, gallium, and indium atoms showed a deviation from the theoretically predicted value. In 1955 he was awarded the Nobel Prize "for his precision determination of the magnetic moment of the electron".

Boris Nikolaevich CHETVERUSHKIN (1934), a mathematician and academician of the Russian Academy of Sciences (2011), an author of over 300 scientific publications, including monographs, the Honored Scientist (2000). He is a specialist in the field of mathematical modeling, applied mathematics and the use of high-performance multiprocessor systems for solving problems in science and technology. He developed algorithms and software systems for solving the equations of radiating gas dynamics, proposed a method for solving gas dynamics problems - kinetically consistent difference schemes.

Vladimir Aramaisovich ABRAMYAN (1934 – 15.10.1977), a Soviet design engineer and inventor, the specialist in the field of passenger car manufacturing. The Chief designer of the Izhevsk Machine-Building Plant (1970-1977). Also, Abramyan is the developer and leader of the implementation of a number of measures that improve the quality of manufacture and operation of the motorcycle and its components, as a result of which the number of complaints has decreased, noise and vibration reduced, and the power of motorcycle engines increased. Under his leadership, cargo versions of the Moskvich-412, Izh-2715 (van), sports modification "Izh-Rally" were developed and put into production.

Jeremy RIFKIN (1945), an American social philosopher, economist, writer, and social activist. He supported the theory of post-capitalism, and promoted the sustainable development and alternative energy. Rifkin is an author of the concept of the "third industrial revolution", and such bestselling books like “The European Dream”, “The Hydrogen Economy”, “The Age of Access”, “The Biotech Century”, and “The End of Work”.

Robert CAILLIAU (1947), a Belgian scientist, who co-invented the technology of the World Wide Web with Sir Timothy Berners-Lee. In 1993, in cooperation with the Fraunhofer Society, Cailliau took on the first Internet project for the European Commission to disseminate information in Europe. After participating in the transfer of Internet technology developments from CERN to the World Wide Web Consortium (W3C), he devoted his time to public relations.
