Talk:Jan Czekajewski

more info can be added
1. Czekajewski's autobiography has many details that could be added here.

2. He sold Columbus Instruments in 2020 or 2021 (and is not a president of it), but I don't have a source for that info that could be cited.

3. Columbus Instruments product Oxymax is claimed to be used in Exxon Valdez oil spill (https://www.colinst.com/about). Rpoleski (talk) 20:55, 9 October 2022 (UTC)
