Louis N. Rosenthal (C.1824-1900s) was a lithographer during the mid to late 19th century. He was born in Turck, Russian Poland and left alongside his brother to avoid being drafted into war. He was sent to London to apprentice under a lithographer, then arrived in New York in 1848 once the apprenticeship ended. Rosenthal then became an established memeber of the lithographic trade in Philadelphia by the next year and had a brief partnership with Peter Kramer in 1850. Max, one of Rosenthal's brothers, was a student of Martin Thurwanger, who had a contract with the Smithsonian Institute in the late 1840s, came to the United States with him and setted up a lithography firm with Louis in 1851. They were known as L.N. Rosenthal or just the Rosenthals. It also seemed that Max was the firm's primary artist, while Louis was running the establishment and acted as the publisher. They published sheet music covers, portraits, maps, labels, advertisements, building views, anatomical and geological charts and Civil War scenes. After relocating twice due to a fire and water damage, the firm closed and Louis moved to Chicago and worked as a lithographer and printer until his death in the 1900s.
