Alexander C. Barry started out in as a Wigmaker in New York City in 1842. His business was located on Broadway. He later claimed that his business had been established in 1801, but I haven't found any evidence of this. There was a Tricopherous advertised as early as 1839 (see Bazin), but it was most likely an import, not Barry's. Barry probably started selling his Tricopherous in the 1840s. By 1850, his primary income was derived from the compound. He continued in the Tricopherous business until around 1870, when he branched out into General Perfumery. From 1871 till 77, Barry listed business addresses which were the same as those of Thomas Barclay & Co. According to the Wilsons, he sold Proprietorship of his medicines to Barclay in 1871. The Wilsons also said that in 1877 Barclay took on a junior partner named John Reuter of Brooklyn, and by the 1890s their company was known as Reuter Barry Inc.
Over the years, several other products were sold under the brand name "Barry's." Barry's Safe Hair Dye was for sale in 1872, and was still being sold at least as late as 1885. In 1880, there was a Barry's Black Hair Dye, in addition to the Safe Hair Dye. In the 1901 Morrison & Plummers catalog, they listed Barry's Antiseptic Mixture, and Barry's Practical Hair Grower. The Tricopherous was for sale well past the turn of the century, in fact, the Trade Mark was re-registered by Barclay & Barclay in 1906 (TM #54,096).
