The Sea Wolf is a 1906 psychological adventure novel by American novelist Jack London about a literary critic, survivor of an ocean collision who comes under the dominance of Wolf Larsen, the powerful and amoral sea captain who rescues him. Its first printing of forty thousand copies were immediately sold out before publication on the strength of London's previous The Call of the Wild. Ambrose Bierce wrote, "The great thing-and it is among the greatest of things-is that tremendous creation, Wolf Larsen... the hewing out and setting up of such a figure is enough for a man to do in one lifetime... The love element, with its absurd suppressions, and impossible proprieties, is awful."
The personal character of the novel's antagonist "Wolf Larsen" was attributed to a real sailor London had known, Captain Alex MacLean. According to London himself, "much of the Sea Wolf is imaginary development, but the basis is Alexander McLean". Captain Alex MacLean, or McLean, was born May 15, 1858 in East Bay, Nova Scotia. He did sail mostly in the Pacific North West with his brother, Captain Dan MacLean. MacLean was at one time the Sheriff of Nome, Alaska. The MacLean Captains maintained their ties to Cape Breton Island despite having spent much of their lives sailing the Pacific Coast and do have living descendants.
London, who was called "Wolf" by his close friends, also used a picture of a wolf on his bookplate, and named his mansion "Wolf House". Given that Van Weyden's experiences in the novel bear some resemblance to experiences London had, or heard told about, when he sailed on the Sophia Sutherland, the autodidact sailor Wolf Larsen has been compared to the autodidact sailor Jack London.
Writing the final rescue of van Weyden and Maud by a US Revenue Cutter London could well have had in mind the USRC Bear since 1885 in service along the Alaskan coast.London's intention in writing The Sea Wolf was "an attack on (Nietzsche's) super man philosophy."
