He was born in Katowice in 1938 and became a press photojournalist out of his passion for photography. He spent forty years working for Dziennik Zachodni and Trybuna Robotnicza, which in those times served as communist propaganda newspapers. Zygmunt Wieczorek’s and other photojournalists’ duties involved documenting the communist party's successes, including growing towns and villages, as well as capturing everyday lives of their residents. It is thanks to them that many documentary (though some retouched and photomontaged) photos have survived, including photo coverages of party congresses held in Silesia, genre scenes with smiling residents, and photo stories with clearly defined messages. Zygmunt Wieczorek continued to work with the camera after 1989, giving testimony to the political and social changes following the collapse of communism.
In the 1970s, he created a series of photographs depicting Tychy architecture, local ceremonies, visits by prominent state and party officials, industry developments and sporting events.
The Museum's collection includes about 60 photographs in digital form, which were donated by the photographer in 2013-2014.
