Robert Chesebrough’s career did begin with work involving whale-derived material: a JAMA Dermatology article reports that in Brooklyn he isolated kerosene from sperm-whale oil. The rise of the petroleum industry threatened that business; later, in Pennsylvania, Chesebrough became interested in residue from oil-drilling equipment and developed petroleum jelly.
