Summary

Two future recipients of the Lomonosov Gold Medal, Corresponding Member of the USSR Academy of Sciences Aleksandr Oparin (right) and senior research worker Andrei Kursanov at the enzymology laboratory, 1938. This photo was scanned from the Soviet magazine Nauka i Zhizn, 1991, issue 1, p.8. The original photo was taken by a prominent Soviet photographer Pavel Troshkin, whose archive features many photos of famous Soviet scientists from the 1930s. Pavel Troshkin died in 1944, at the front of the Great Patriotic War.

This file is a Ukrainian or Ukrainian SSR work and it is presently in the public domain in Ukraine, because it was published before January 1, 1951, and the creator (if known) died before that date. (This is the effect of the retroactive Ukrainian copyright law of 1993 and the copyright from 50 to 70 years in 2001.) A Ukrainian or Ukrainian SSR work that is in the public domain in Ukraine according to this rule is in the public domain in the U.S. only if it was in the public domain in Ukraine before January 1, 1996, e.g. if it was published before January 1, 1946 and the creator died before this date, and no copyright was registered in the U.S. (This is the combined effect of the retroactive [1], Ukraine's joining the Berne Convention in 1996, and of 17 USC 104A with its critical date of January 1, 1996.)
