This Day in History: 1835-01-02

Carl Friedrich Wilhelm Claus was born this day. A German zoologist, Professor of Zoology at the University of Vienna, he was the first prominent scientist to devote most of his career to copepods, publishing the first book dealing solely with the topic.
He is honoured in the name of the family Clausiidae and six of its genera along with numerous species names.

Copepod, derived from Greek, Cope-, kwph, handle, oar-handle – hence oar; -pod, podos, pous, foot; inferring ‘oar-footed’ alluding to the paired swimming legs that move together in a sculling motion.
