He was director of the Grigore Antipa National Museum of Natural History (1892 - 1944). His paper Principes et moyens pour la réorganisation des musées d'histoire naturelle was published in 1934. Starting from the reorganization of the Bucharest museum, in 1907 biological dioramas were used for the first time. The first dioramas illustrated the Carpathian Mountains, the Bărăgan Plain, and the Danube Delta. The Museum of Natural History also has dioramas depicting the fauna of the tundra, prairie, savannah or Sahara desert regions. Several museums worldwide asked for his assistance as a consultant as a result of this work. Grigore Antipa was a member of the Romanian Academy
