Franz Seraph Lenbach (1836–1904), later Ritter von Lenbach, was a German painter born in Schrobenhausen and active in Munich. He was associated with the Munich School and the realist movement, primarily working as a portraitist. Lenbach also worked as a lecturer and draftsman.
Lenbach specialized in portraits of influential personalities from European nobility, the arts, and industry. His sitters included Otto von Bismarck, Kaiser Wilhelm I, Kaiser Wilhelm II, Kaiser Franz Josef I, and Pope Leo XIII. His realist approach captured the likenesses of these figures, establishing him as a significant portrait painter of his era in Germany and Austria.
