Johan Hörner (28 January 1711, Edebo, in Roslagen - 4 March 1763, Copenhagen) was a Swedish-born Danish portrait painter.
For a time, he helped find refuge for other self-exiled Swedes, but soon came under scrutiny for his activities and moved to the countryside.
[2] In 1741, a new wave of Pietist refugees arrived in Copenhagen; including Sven Rosén, a major figure in the movement.
Hörner attempted to win an appointment as court painter but, despite the fact that King Christian VI was sympathetic to the Pietists, he was not accepted.
A portrait of the naval officer, Adam Frederik Lützow [da], was first determined to be his as recently as 2007.
