sharks would fatally wound a living person in the temperate waters of the northeastern United States without provocation. One skeptical scientist wrote, "There is a great difference between being attacked by a shark and being bitten by one." He believed that sharks tangled in fishing nets or feeding on carrion might accidentally bite a nearby human. In 1891, millionaire banker and adventurer Hermann Oelrichs offered a $500 reward in the New York Sun "for an authenticated case of a man having been attacked by a shark in [the] temperate waters" north of Cape Hatteras, North Carolina. He wanted proof that "in temperate waters even one man, woman, or child, while alive, was ever attacked by a shark." The reward went unclaimed and scientists remained convinced that the upper eastern coast of the United States was inhabited by harmless sharks. Academics were skeptical that a shark could produce fatal wounds on human victims. Ichthyologist Henry Weed Fowler and curator Henry Skinner of the Academy of Natural Sciences in Philadelphia asserted that a shark's jaws did not have the power to sever a human leg in a single bite. Frederic Lucas, director of the American Museum of Natural History, questioned whether a shark even as large as 30 feet (9 m) could snap a human bone. He told The Philadelphia Inquirer in early 1916 that "it is beyond the power even of the largest Carcharodon to sever the leg of an adult man." Lucas summed up his argument by pointing to Oelrichs's unclaimed reward and that the chances of being bitten by a shark were "infinitely less than that of being struck by lightning and that there is practically no danger of an attack from a shark about our coasts." The Jersey Shore attacks compelled scientists in the United States to revise their assumptions that sharks were timid and powerless. In July 1916, ichthyologist and editor for the National Geographic Society Hugh McCormick Smith published an article in the Newark Star-Eagle describing some shark species as "harmless as doves and others the incarnation of ferocity." He continued, "One of the most prodigious, and perhaps the most formidable of sharks is the man-eater, Carcharodon carcharias [great white]. It roams through all temperate and tropical seas, and everywhere is an object of dread. Its maximum length is forty feet and its teeth are three inches (76 mm) long." By the end of July 1916,
