J. B. Hobson

J. B. Hobson appears only briefly in the novel, but his single action is decisive: he recruits Professor Pierre Aronnax for the hunt that leads to the discovery of the Nautilus. As the United States Secretary of the Navy, Hobson represents the institutional authority of the American government, which, in response to public alarm over a series of maritime accidents, commissions the frigate Abraham Lincoln to purge the seas of the unknown creature. His letter to Aronnax, dated just three hours before the ship's departure from its Brooklyn pier, is the catalyst that transforms the professor from a skeptical scientist into an active participant in the chase. The letter, written in a formal and cordial tone, offers Aronnax a cabin at Commander Farragut's disposal and expresses the government's wish to have him as France's representative on the undertaking. This invitation, which Aronnax accepts without hesitation, abruptly ends his plans to return to France and instead launches him into the extraordinary underwater voyage that forms the core of the book. Hobson himself never appears again in the narrative; his function is purely that of a herald, a figure whose single official act sets the protagonist on a path from which there is no easy return. His name, however, is recorded in the novel's opening chapters as the author of the letter that changes Aronnax's life, and it is through this letter that the reader first understands the scale of the international concern surrounding the monster. The Secretary's role underscores the theme of institutional power and the way in which scientific curiosity can be conscripted into national projects, even those as speculative as hunting a mythical beast.
