by Igor SILKIN, Director of the Zavoisky Memorial Laboratory, Kazan (Volga Region) Federal University (Kazan, Tatarstan) In 1994 an exhibition of physical instruments of the 19th-early 20th centuries took place at the International AMPERE Congress. It was devoted to the 50th anniversary of the discovery of electron paramagnetic resonance (EPR), with Kazan State University as the host. For one, it featured a unique exhibit: a working setup for observing the absorption effect of a radio-frequency field described in the doctoral thesis of the experimental physicist Yevgeny Zavoisky. Using this setup, he made a pioneering discovery in 1944, thus laying the foundation for a new dynamic area in modern physics, the magnetic radio spectroscopy. The Kazan exhibits aroused genuine interest among Russian and foreign participants. They came up with an idea of a memorial laboratory in the university. Three years later its directorate set aside lecture room 253 (today 246), where EPR had been discovered, for this purpose. For Kazan University the name of Zavoisky* in physics is as meaningful as the name of the creator of non-Euclidean geometry (1826) Nikolai Lobachevsky in mathematics, the author of the theory of the organic compound structure (1861) Alexander Butlerov in chemistry and linguist and Slavicist Jean Baudouin de Courtenay in philology. A member of the national Academy of Sciences, a Stalin (1949) and Lenin Prize (1957) winner and Hero of Socialist Labor (1969), Zavoisky was born in Mogilev-Podolsk of the Vinnitsa Region (Ukraine) in 1907. Almost forty years of his life were associated with Kazan, a city on the Volga. His family moved there in August of 1908. First he attended a three-grade primary school (1915-1917) and then the * See: V.
