Leonhard Sigmund Friedrich Kuno Klaus Schultze-Jena (May 28, 1872, in Jena – March 28, 1955, in Marburg) was a German explorer, zoologist, and anthropologist known for his explorations of German Southwest Africa and New Guinea, as well as for his studies on Mesoamerican languages.
[1][2] During the Herero and Namaqua genocide, Schultze, a witness, took "body parts from fresh native corpses" which according to him was a "welcome addition".
He also noted that he could use prisoners for that purpose.
[3] In 1912, he adopted the surname Schultze-Jena from an honorary title that was given to his father, gynecologist and obstetrician Bernhard Sigmund Schultze.
[4] The Leonhard Schultze River and Leonhard Schultze languages of Papua New Guinea are named after him, as well as three species of reptiles: Elseya schultzei, Monopeltis leonhardi, and Sphenomorphus schultzei.
