Carl Hunstein

Carl Hunstein was a German ornithologist and plant collector.
Hunstein was born in Homberg, Germany. He emigrated to America, then relocated to New Zealand. From 1885 until his death, he was employed by the German New Guinea Company.
He was a successful discoverer of new species of birds-of-paradise, such as the:

Brown sicklebill, named in honor of Adolf Bernard Meyer.
Stephanie's astrapia, named in honor of Princess Stéphanie of Belgium.
Blue bird-of-paradise, named in honor of Crown Prince Rudolf of Austria.
Emperor bird-of-paradise.

Hunstein died when a tsunami, caused by a submarine volcano, hit the coast of New Britain of the Bismarck Archipelago.
He is commemorated in New Guinea by the Hunstein Mountains and the Hunstein Forest, and in plants and animals including the Hunstein's mannikin, Cyathea hunsteiniana and Araucaria hunsteinii.
