Even though he was regarded as one of the top Polish gynecologists (he was an assistant to the famous doctor Henryk Jordan), he is most renowned as director of Cracovia, which in the 1920s and 1930s was one of the strongest sports clubs in Poland.
During this time, Cracovia, in spite of financial crises shaking Poland, became a team known all over Europe.
He had always been keen on preserving the amateur character of Polish football, and this attitude became old fashioned as time went by.
Cetnarowski died suddenly on 3 September 1933 in Kraków, at the age of 55, during the game of Cracovia's female handball team.
The funeral was a big event in Kraków, thousands of mourners gathered to bid him final farewell.
