Norman Friend (1814-1888) was a Danish - American lithographer and engraver, specializing in map work. He worked in Philadelphia throughout the second half of the 19th century, having immigrated to the United States in the early 1840s. He began his naturalization in and around 1844. He was certainly a citizen by 1851, at which point he served as the citizenship sponsor to Jacob Aub, with whom he partnered in the firm of Friend and Aub. After Aub's departure to the military in 1861, Friend continued to operate at the address under his own name until his death. Friend and Aub executed maps for many publishers, including Walling, McIntyre, Bridgens, and Otley.
