He was born in Poznań and studied at the Faculty of Law and Economy of the Humboldt University of Berlin. He was one of the leading publicists of the National Democracy who tackled the issues connected with Germany. From 1931 Drobnik was a permanent Berlin correspondent of “Gazeta Warszawska” and “Kurier Poznański”. His articles published in the two largest National dailies, as well as in the columns of other socio-political magazines – such as “Awangarda”, “Myśl Narodowa”, or “Przegląd Wszechpolski” – exerted a significant influence upon the evolution of the National Democracy’s attitude to the German question and to Nazism. Fascinated with the idea of the ‘total state’, Drobnik, together with Jan Zdzitowiecki, Zdzisław Stahl, Zygmunt Wojciechowski, Ryszard Piestrzyński, and Klaudiusz Hrabyk, founded the Union of Young Nationalists in Poznań in November 1933.
