Christian August Lorentzen
(1830 - 1902)
 

Christian August Lorentzen was a Danish painter. He was born in Sønderborg, Denmark. He was the son of Hans Peter Lorentzen and Maria Christina Hansdatter. His father was a watchmaker. He arrived in Copenhagen around 1771 where he frequented the Royal Academy of Fine Arts but it is unclear whether he received formal training. After arriving in Copenhagen, he was soon used as a portrait painter. From 1779 to 1782 he went abroad to develop his skills, visiting the Netherlands, Antwerp and Paris where he copied old masters. In 1792 he traveled to Norway to paint prospects.
