label: Description (Brief)
content: August Hoen (1817-1886) was born in Germany and came to the United States with his family in 1835. He worked with his cousin Edward Weber in a Baltimore lithographic shop. After Weber's death in 1848 Hoen took over the company and renamed it the A. Hoen & Company. Both under Weber and Hoen, the shop specialized in manufacturers' ornamental labels, and was known for its exceptional color work. Hoen's lithocaustic process was well adapted to this work.
