Marian Auerbach also known as Majer Auerbach was a Polish classical philologist of Jewish background.
He graduated from the Philology Department of the University of Lwów, where he received his doctorate in 1911 and his habilitation in 1932.
Auerbach lectured there, and died at the hands of Gestapo during the Holocaust in Poland. He published the first complete Polish university textbook on the Greek Grammar in 1935, which was repeatedly reprinted. Marian Auerbach is not to be confused with Herman Auerbach (1901–1942), prominent mathematician, professor at the Department of Mathematics at the Lwów University murdered in 1942 at the Lwów Ghetto.
Auerbach was an associate member of the Scientific Society of Lwów (now Lviv, Ukraine), as well as the co-contributor of the Polish Academy of Sciences Philological Commission.
