Friderich Martens

Friderich Martens (1635–1699) was a German feldsher and naturalist who conducted the first scientific observations of the nature, animal life, and climate of Svalbard. He published his notes in the book "Spitzbergische oder Groenlandische Reise-Beschreibung", translated in English as "Svalbard and Greenland Travelogue." This book became a reference work for many decades.
