Otto von Kotzebue

Otto von Kotzebue (30 December 1787 - 15 February 1846) was a Russian naval officer in the Imperial Russian Navy. He commanded two naval expeditions into the Pacific for the purposes of exploration and scientific investigation. The first expedition explored Oceania and the western coast of North America, and passed through the Bering Strait in search of a passage across the Arctic Ocean. His second voyage was intended as a military resupply mission to Kamchatka but again included significant explorations of the west coast of North America and Oceania. Provided by Wikipedia
