[2] Johann Franz Schefold (1750-1828), a lawyer whose father was a church painter, acted as a sort of patron to Pflug, allowing him access to his library and gallery.
In 1806, he went to the Academy of Fine Arts Munich where he studied under Johann Christian von Mannlich, whose instruction consisted largely of having him make copies of the Dutch Masters.
[2] Beginning in 1813, his painting focused largely on genre scenes and costume pictures of soldiers or robbers.
[1] As a teacher, he discovered and promoted many young artists who would come to be called "The Biberach School".
Taken together with his Memoirs (published in 1874), his works offer an almost complete representation of daily life in Nineteenth-century Germany and have great historical value, beyond their artistic merits.
