Lev (Leo) Mikhailovich Lopatin (Russian: Лев Миха́йлович Лопа́тин; 13 June 1855, Moscow – 21 March 1920, Moscow) was a Russian philosopher and former head of the Moscow Psychological Society until the formal liquidation of the society by the Soviet after the Revolution of 1917. Lopatin fell victim to the policies of Soviet reform, which caused widespread famine, and in 1920 he died due to malnourishment and exhaustion. Source: Wikipedia (en)
