Władysław Rajmund Leppert (born December 25, 1848 in Łążek - June 12, 1920 in Warsaw) - Polish chemist and industrialist. Studied at the Main School in Warsaw, from 1877 assistant at the University of Warsaw in the Department of Chemistry. Together with his father-in-law Wincenty Karpinski, he founded a paint and varnish factory in Helenówek near Pruszkow, which he later ran independently. He co-founded the first Polish chemical journal Chemik Polski and was a member of the Society of Technicians in Warsaw; also one of the organizers of the Polish Chemical Society. Also a historian of the development of chemistry in Poland - he is the author of the work Rys rozwoju chemii w Polsce do 1830 (1918). In 1920 he was appointed honorary professor of chemical technology at the Warsaw University of Technology. He is buried in the Powązki cemetery.
The Paint and Varnish Factory was established in 1880, after the Warsaw-Vienna Railway was launched with a stop in Pruszkow. It produced inks, which were quickly introduced to Warsaw printing houses; in addition, Leppert obtained several patents, including a new method of obtaining acetic acid, which was imported abroad.
