designation
(2394) Nadeev was named after the Soviet astrometrician and geodesist Lev Nikolajewitsch Nadejew (1902–1974), who carried out extensive geodetic studies in the northern Soviet Union. He founded the Laboratory for Time and Frequency in the city of Irkutsk , after which the asteroid (3224) Irkutsk is named. It was there that the explorer Nikolai Stepanowitsch Tschernych began his career under Nadeev's direction.
