Max Adler was born in Vienna and studied law at the University of Vienna, and became Professor of Sociology in 1920. From his youth, he was an active member in the Socialist movement, and was a member of the Austrian parliament from the Social Democratic Party for more than twenty years. In his theories, Max Adler combined the classic Marxist theory of social interaction with concepts of the human mind. Along with O Bauer, he developed the conmcept of Austro-Marxism, and formulated a code of Socialist ethics in which he introduced the term of Neuer Mensch (“a new human being”).
