2108 Otto Schmidt           Discovered 1948 Oct. 4 by P. F. Shajn at Simeis.
Named in memory of Otto Yul'evich Schmidt (1891-1956), a prominent Soviet scientist famous for his investigations in mathematics, astronomy and geophysics. He was also an outstanding Arctic researcher, academician and statesman. His cosmogonic theories contributed extensively to the evolution of concepts on the formation of the earth and other planets.
