Hercules Sanche (1838-1928) was a peripatetic healer who, in the 1890s, obtained patents in Canada, England, Germany, Spain, and Switzerland. Sanche also advertised widely. The Oxydonor, he promised, “supplies Oxygen to the blood, and cures disease and pain under Nature’s own laws.” Inscriptions on this example refer to several patents and trademark registrations.
