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.

约翰·迈克尔·冯·赫尔曼 (Johann Michael von Hermann) (1793–1855)：马克斯·施韦德勒的前任？

摘要 十九世纪初著名的修复师约翰·迈克尔·冯·赫尔曼（1793-1855）早已被人遗忘。最近在 Staatliche Graphische Sammlung München 发现了他与旧版大师版画相关的作品，这使得他能够仔细研究他以及他的学生 Ludwig Albert von Montmorillon（1794-1854 年）的方法和技巧，从而提供了一个全新的视角。纸张保护的早期历史。在 Max Schweidler (1885-1953) 于 1938 年描述这些方法之前，冯赫尔曼的传真插入方法受到了他的同时代人的赞扬。本文提供了两位 19 世纪修复者的传记，给出了他们处理过的版画的例子，并添加了一章保护历史认为他们在学科历史上占有一席之地。总之，
