John DeWolf (sea captain)
John DeWolf (6 September 1779 - 6 March 1872), also known as John D'Wolf, John D'Wolfe, John DeWolfe, John DeWolf II, Norwest John or Nor'west John, was a sea captain, merchant, and businessman known for his role in the maritime fur trade in the Pacific Northwest, and his influence on the Russian-American Company in Novo-Arkhangelsk (today Sitka, Alaska) in Russian America, and for being an uncle of Herman Melville. Melville was inspired by DeWolf's stories, including an encounter with a large whale that contributed to Melville's Moby-Dick, which Melville describes explicitly in Moby Dick, "Chapter XLV: The Affidavit".
