En octobre 1846 William Thomas Green Morton, un dentiste américain , conduit la première anesthésie générale avec de l'éther qui eu un grand écho dans la presse .John Snow assista dès le 28 décembre 1846 à une démonstration conduite par le dentiste James Robinson à Londres . Préparé par ses recherches sur l'asphyxie dans ses effets sur l'appareil circulatoire il s'intéressa immédiatement au procédé qu'il améliora à tel point qu'en peu de temps , cette technique dédaignée car jugée d'abord peu fiable ,fut adoptée par les plus grands chirurgiens de Londres . En 1847 , Snow publie On the Inhalation of the Vapor of Ether.
La même année il commence à s'intéresser à l'usage anesthésique du chloroforme découvert alors par James Young Simpson à Edinburgh . Il administra lui-même du chloroforme à la reine Victoria à l'occasion de la naissance de Leopold en 1853, puis de Beatrice en 1857 .
