Helmut Humbach, born in 1921, emeritus professor of Comparative (Indoeuropean) Linguistics at Johannes Gutenberg University Mainz (Germany), studied Indoeuropean and Classical Philology in Munich. In 1956 he was appointed to a chair at the University of the Saarland, in 1961 he accepted the chair at Mainz University. To the current formalism of linguistic prehistory, he preferred the philological and historical approach to texts of the past, which he consistently carried out in teaching and research. His expertise has been requested and welcome all over the world.
