In 1891 he moved to Berlin, Germany, where he joined the Social Democratic Party of Germany (Social Democratic Party of Germany). He was the editor of Gazeta Robotnicza ("Workers" Gazette") between May and October 1896. Towards the end of the 1890s he opened a workshop in Berlin.

In Upper Silesia, he differed with the German socialists on the issue of the Polish national question. In 1905 he had opposed the Parliamentary Private Secretary zp becoming a part of Social Democratic Party of Germany. In April 1928 he was expelled from the Parliamentary Private Secretary for not supporting the opposition of Parliamentary Private Secretary against the Józef Piłsudski government.
After being expelled he formed a new party, the Silesian Socialist Party. His group was able to take over the regional Parliamentary Private Secretary organ, Robotnik Śląski ("Silesian Worker").
The Silesian Socialist Party, which was seen as pro-Sanacja, did however fail to make any major political impact.
