Birney J. Kendall was a successful Patent Medicine Proprietor in Enosburg Falls, Vermont starting prior to 1872. According to Fike, he introduced his "Blackberry Balsam" that year. His most well known preparation was his "Spavin Cure," for which he registered a trademark in 1876.
In 1883, B. J. Kendall & Co. consisted of Kendall, Carmi L March, Olin Merrill, and Moses F. Perley. That year they registered "Kendall's Glyceroil" as a trademark for a "Hair Restorer & Invigorator.". They said that the brand name had been used since 1880, by Andrew and Alfred Rublee, of the same town. They apparently bought the brand from the Rublee Brothers in 1883. Fike said that by 1884, Kendall had turned over the management of the business to others, and that by 1889, he had sold his interest. Since this label discusses the Pure Food & Drug Act of 1906, we know it was made at least that late.
