From Wikipedia: Carl Saltzmann (1847 - 1923) was a German marine and landscape painter.
Saltzmann's painting "Walfang mit der Duncan Grey" (Whaling with the Duncan Grey) depicted the 15 July 1892 "pleasure whaling trip" taken by German Emperor Wilhelm II on the whaling and sealing vessel Duncan Grey, during which a sei whale was harpooned with explosive shells and hauled back to shore
