Johann Michael von Hermann (1793–1855): A predecessor of Max Schweidler?

Abstract The restorer Johann Michael von Hermann (1793–1855), famous in the early nineteenth century, has long fallen into oblivion. A recent discovery of his work associated with old master prints at the Staatliche Graphische Sammlung München has allowed a close study of his methods and skills as well as those of his pupil Ludwig Albert von Montmorillon (1794–1854), providing a fresh perspective on the early history of paper conservation. Von Hermann’s method of facsimile inserts was praised by his contemporaries, before Max Schweidler (1885–1953) described these methods in 1938. The present article provides biographical notes on both nineteenth century restorers, gives examples of prints treated by them and adds a chapter of conservation history crediting them with a place in the history of the discipline. In summary, this offers a surprising insight on how works of art used to be almost untraceably restored by this team of Munich-based restorers more than 150 years before Schweidler.
