Ludwig Ferdinand Schnorr von Carolsfeld (11 October 1788 – 13 April 1853) was a German Romantic painter, engraver and lithographer.
Schnorr von Carolsfeld was born in Königsberg, the son and pupil of the artist Veit Hanns Schnorr von Carolsfeld. His younger brother was Julius Schnorr von Carolsfeld and his nephew was the opera singer Ludwig Schnorr von Carolsfeld.
At the age of 16 he moved to Vienna, where he lived for the rest of his life.
In 1804 he was registered as a student in the Academy of Fine Arts in Vienna under Heinrich Friedrich Füger, who had become acquainted with his father in 1801. He became part of the group of Academy students round Friedrich Overbeck, who were looking for new paths beyond the strongly formal Classical ideals of the Academy. The outcome of their efforts was the Nazarene movement. Unlike Overbeck and others, however, Schnorr von Carolsfeld avoided a complete break with the Academy, did not join the Lukasbund (a group founded by the other Nazarene artists), and remained in Vienna. His first patron was Duke Albert von Sachsen-Teschen. Schnorr von Carolsfeld maintained close relations with the Catholic Romantics Zacharias Werner and Friedrich von Schlegel.
In about 1808 he formed part of the circle of friends centred on Therese Malfatti and her family and drew portraits of Ludwig van Beethoven and his friend Ignaz von Gleichenstein.
