Charles Wachsmuth

Charles Wachsmuth (September 13, 1829 – February 7, 1896) was a German-American paleontologist and businessman. After emigrating to the United States, he became a renowned expert on the Paleozoic fossil animals known as crinoids. He and his collaborator, Frank Springer, published numerous articles on the subject and built an exceptional collection of crinoid fossils. The culmination of his work was the two-volume "Monograph of the North American Crinoidea Camerata", coauthored with Springer and published posthumously in 1897. Provided by Wikipedia
