Gotthelf Fischer von Waldheim

Gotthelf Fischer von Waldheim (Russian: Григо́рий Ива́нович Фи́шер фон Ва́льдгейм, romanized: Grigórij Ivánovič Fíšer fon Vál'dgejm; 13 October 1771 – 18 October 1853) was a Saxon anatomist, entomologist and paleontologist.

He travelled to Vienna and Paris with his friend Alexander von Humboldt and studied under Georges Cuvier.

In August 1805, he founded the Société Impériale des Naturalistes de Moscou.

[2][3] Fischer was mainly engaged in the classification of invertebrates, the result of which was his Entomographia Imperii Rossici (1820–1851).

Due to his work studying the insects of Russia, the Russian government granted him nobility as well as the "von Waldheim" ending to his name.
