The article presents two likely and so far unknown compilers of the third edition of Koniáš’s Key from 1770. Their names have been revealed by a handwritten note in a copy that was originally a part of the library of the private collector Josef Bartsch (1731–1803). Concerning the first figure, the Jesuit Josef Kögler, the treatise describes his career in the Jesuit Order and the posts that he held. In the case of his co-worker Jan Kohout, the text outlines the possible connections that might help identify him precisely.
