Henry Stonebraker was a successful Patent Medicine Manufacturer in Baltimore from the 1860s until around 1905. In 1869, he was listed alone; then, in 1871, the business was called H. Stonebraker & Sons (John A. and Charles H.). In 1902, the business name changed to Stonebraker Chemical Co., and they were at 105 N. Liberty. In 1906, John and Charles were running a Wine & Liquor business. Most likely, their father Henry had died around 1905. The Stonebraker Chemical Co was still in business until at least 1914, but it was probably owned by others.
