The Goldman family, were in almost every kind of hair related business from 1869 until well into the 20th century. There were at least 3 family members in the business. Moses Goldman was in the Hair Goods business in Detroit from 1869 until 1873. He was the Manager of the European Hair Store in Toledo, Ohio, from 1879 until 1888. His business was on Summit, initially at #157. There was a Daughter named Miss Rose G. Goldman, who was working in the business as a Hair Worker from 1882 through 1884. I didn't find Mary Goldman listed in the Toledo Directories, but she was probably Moses' wife.
When Mary Goldman registered a Patent in 1880 her address on the Letters of Patent indicated that she was from Toledo. Moses Goldman may have died in 1888, because he was no longer listed after that date, and Mary moved to Minneapolis, Minnesota around that time. I found Mary listed in the Hair Goods business in Minneapolis from 1888 until 1890. For that period, she was on Nicollet Avenue, which was the same street that Sarah Farr was doing business on. Not coincidentally, the Farr's Gray Hair Restorer and the bottle shown are very similar. The Goldman family finally settled in St Paul, Minnesota sometime in the 1890s, and their success story continued.
Isaac Goldman was listed as a Wigmaker (1898-1900), and Manager of the European Hair Parlors (1908-1910). Bejamin T. Goldman was listed as a Clerk (1899), Travelling Agent (1901-2), and the Manager of the Toilet Preparation Business (1905-8), Hair Tonic (1909), Manager of Mary T. Goldman Co. (1910-14), and by 1919, he was just listed as Hair Dye. Mary T. Goldman was listed in the Hair Goods business (1900), and Proprietor of European Hair Parlors (1901-6). Moses Goldman was listed in 1905 and 1906, as the Manager of the Hair Parlors. Out of this whole family in the Hair business, Benjamin T Goldman was the one who primarily marketed the well known Hair Tonic in the bottles we see.
Benjamin T. Goldman registered a picture Trade Mark for a "Hair Restorer" in 1906. He claimed that he or his predecessor had been selling the Tonic since 1901. I can only venture to guess that his predecessor was Mary T. Goldman. According to Fike, the Goldman products were bought out by Monroe Chemical Co. of Quincy, Ill., in 1929. They had, in fact renewed the Trade Mark on the product in 1932 and 1952. In 1922, the word "Goldman's" was registered as a Trade Mark for Hair Dyes & Tonics (TM #155,696). They indicated at that time that their name had been used on hair preparations since 1870.
Fike also said that a labeled variant of the bottle called the product "Gray's Hair Restorative." It's possible that Mary Goldman acquired the brand from Day Hoagland & Stiger sometime after 1866. Another possibility is that the other Gray's Hair Restorative had completely faded by then, and that she had another source. There was an Orrin Gray in Minneapolis in 1890 who claimed to be in the Patent Medicine business, but the directory didn't say what his product was. It's very possible that he invented the preparation for Mary Goldman originally.
