Szymon Tenenbaum

His vast collections of insects were saved during the second world war by Antonina and Jan Żabiński at the Warsaw Zoo.

He specialized especially in the beetles, naming his first new species from the Balearic Islands (visiting it in 1913) after his teacher, Dendarus hildti.

Tenenbaum wrote a zoological guide to the vicinity of Warsaw (Przewodnik zoologiczny po okolicach Warszawy) with Stanisław Michał Sumiński in 1921 which describes the habitats in the region including many that no longer exist.

During the German invasion of Poland in 1939 he was trapped in the Warsaw Ghetto, locked up with his wife Eleonora and daughter Irena.

He became unwell, and although his friends the Żabiński couple (depicted in the film The Zookeeper's Wife) offered to organize his escape, he refused and died at home.
