Abstract

Karl Eugen Müller's contribution to the development of the algebra of logic is perhaps the most important part of his scientific work. Müller, who became Gymnasialprofessor after his university studies, was a student of Ernst Schröder's friend, the mathematician Jakob Lüroth. As a result of publishing two papers on problems related to Schröder's monumental Vorlesungen iiber die Algebra der Logik, Müller was commissioned by the Deutsche Mathematiker- Vereinigung with the editing of the unpublished parts of the Vorlesungen from Schröder's Nachla?. Müller worked on Schröder's papers until 1910, but did not bring this work to a conclusion. Müller's own Nachla?, including those parts of Schröder's papers still in his possession, was destroyed in Frankfurt a.M. in 1943, so there remains no hope of finding through Müller any part of the missing Nachla? of Schröder
