The idea of using canaries is credited to John Scott Haldane, known to some as โ€œthe father of oxygen therapy.โ€ His research on carbon monoxide led him to recommend using the birds, writes Esther Inglis-Arkell for Gizmodo. He suggested using a sentinel species: an animal more sensitive to the colorless, odorless carbon monoxide and other poisonous gases than humans. If the animal became ill or died, that would give miners a warning to evacuate.
