This is the second essay of a two-part series on the life and collecting activities of Albert Koch. After Koch traveled to England where he sold his Missourium to the British Museum, the American mastodon that now stands in the Natural History Museum of London, he then went to his homeland in Germany. Koch left his family in Dresden, when he again departed for the United States to pursue some additional paleontological adventures. Following several weeks of travel, he arrived in Alabama where he excavated the remains of a large, archaeocete whale, that he named the Hydrarchos. Koch displayed the skeleton in New York, and several other eastern cities before taking it to Europe. When in Berlin, Koch was able to sell the skeleton to King Friedrich Wilhelm IV of Prussia who placed it in the Royal Museum. Soon thereafter, Koch returned to the United States and Alabama to discover a second whale skeleton. He took this skeleton to Europe where it was exhibited in several cities but, having received no offers, Koch returned with his second Hydrarchos to the United States where it was initially displayed in New Orleans, then St. Louis, and eventually Chicago. In his later years, Koch turned his attention to the Academy of Science of St. Louis where he became an active member and curator, as well as a prospector for minerals. This essay examines the final chapters of Koch’s life and his entrepreneurial showmanship tendencies versus contributions he may have made to science. This narrative is a sequel to an article published in Volume 41 Number 2 of Earth Sciences History that focused on Albert Koch’s Missourium. Together, the two essays capture the life and career of Albert C. Koch.
