Gatschenberger Richard Gatschenberger 
Grundzüge einer Psychologie des Zeichens (1901) [PDF ebook] 

Although Richard Gätschenberger can be regarded as one of the important sign theorists in the first third of the 20
th century, nothing much about the man and his works is currently known. Long before there was a widespread philosophical interest in language, Gätschenberger had already laid the foundations of a semiotic turn although the linguistic turn had not even happened; but his role as a pioneer is one reason for the comparatively small response to his sematology. This volume contains a facsimile reprint of the Regensburger 1901 edition of Richard Gätschenberger’s dissertation
Grundzüge einer Psychologie des Zeichens, and is preceded by a preface ‘Sematology as a Basic Science’ by Achim Eschbach.
