The film's title, "Wieleżyński – Alchemist from Lviv," refers to the pseudonym Marian Wieleżyński used during his student days. Wieleżyński, like the alchemists of old, made an extraordinary discovery – he found a way to use gas. The film commemorates the successor of Ignacy Łukasiewicz, an inventor and visionary, the father of the Polish gas industry, and the founder of the first company in Poland based on employee stock ownership. A vibrant, energetic chemist who, along with Władysław Szaynok and Ignacy Mościcki, embodied a creative version of patriotism.
