Friedrich Siebenrock

In 1886, he began work as a volunteer at the Naturhistorisches Museum,[1] where he would subsequently spend the remainder of his career.

In 1919 he succeeded Franz Steindachner as curator of the amphibian and reptile section at the museum.

[2] His primary scientific research was dedicated to turtles, publishing a number of works on their morphology and systematics.

At the museum, he worked on specimens collected by Viktor Pietschmann in Mesopotamia and Kurdistan; on Alfred Voeltzkow's zoological collections from East Africa, on Rudolf Grauer's Belgian Congo collections and with Steindachner's herpetological specimens from Brazil.

In 1895 and 1897, he accompanied Steindachner on the Ersten und Zweiten Österreichischen Expedition nach dem Roten Meer (First and Second Austrian Expeditions to the Red Sea).
