L. Prang and Company was a created in 1860 by Louis Prang (1824-1909), an Prussian-American printer and lithographer, by buying out his partner's share in Prang and Mayer, a company created in 1856 to produce lithographs. The firm became very successful and was known for its Civil War maps.
In 1886, the company published a series of prints known as the Prang's War Pictures which helped inspire prints by companies such as Kurz and Allison. In 1897, the company merged with another to form Taber-Prang Company which filed for bankruptcy around 1938.
Prang was born in Breslau in Prussian Silesia to a father of French Huguenot origin. He lived in Switzerland before emigrating to Boston, Massachusetts, in 1850.
