Walter John König (Polish: Walter Jan König; 25 June 1903 – 26 February 1966) was an Austrian-Polish inventor, industrialist and soldier who fought for Polish freedom during the Second World War.
No sooner did Poland regain its independence than he acquired Polish citizenship.
König founded the "Rogolith" company in Bielsko, which produced buttons from these artificial materials.
In 1946, however, he managed to bring his wife back from the USSR, and a year later he was called to receive Polish citizenship.
For the next years he was subject to surveillance and even arrested under false charges of stealing materials from his workplace.
Nevertheless, he did not want to leave Poland to go to Sweden for treatment because he knew that the communist authorities would not allow him to return to his homeland.
