Stephen Green Ltd , patent medicine manufacturer

Preservation and the care of records are perhaps inherent in a firm which manufactures a patent medicine, since its existence depends upon the careful protection and safe descent of an original recipe or formula. According to tradition the ointment in question was invented by a Lambeth doctor, Thomas Johnson, in the seventeenth century. It was used for eye complaints. On his death it passed to the Hind family, passing from them when a daughter married Thomas Singleton and took the recipe with her as a marriage portion. Thomas Singleton died in 1779 leaving the recipe to his son William and on his death it passed via his daughter to the Folgham family.

Stephen Green, the Lambeth stone potter, married into this family and by 1848 acquired the proprietorship of the recipe. It eventually passed to the Carlill family who continued manufacture as Stephen Green Ltd. The descent of the recipe was surrounded by many ad hoc legal safeguards, designed to preserve its secrecy. Where they failed, elaborate litigation commenced between claimants to the proprietorship and this accounts for the preservation of deeds and settlements of the eighteenth and early nineteenth centuries. The remaining early material seems to have survived largely as a result of the prominence given to the "historic" nature of the firm in its publicity, a feature which Stephen Green, in particular, seems to have emphasised.
