Gustav Janeček

Gustav Janeček (30 November 1848 – 8 September 1929) was a Czech-born Croatian chemist and pharmacist. He served as rector of the University of Zagreb and president of the Croatian Academy of Sciences and Arts (then JAZU). He is credited with establishing modern university chemistry and pharmacy teaching in Croatia and with helping to develop the country's early pharmaceutical industry through the firms Isis and Kaštel (the latter later becoming PLIVA).

Early life and education Janeček was born in Konopiště, Bohemia, Austrian Empire (now part of Benešov in the Czech Republic). After pharmacy training and assistant work in Prague, he completed a doctorate in chemistry at the Charles University in 1875 and spent several years in Vienna associated with the laboratory of Adolf Lieben.

Industry Parallel to his academic work, Janeček helped initiate Croatian pharmaceutical production. In 1918 he founded the wholesale drug company Isis (today Medika). In 1921 he co-founded the pharmaceutical factory Kaštel d.d. in Karlovac as a joint venture with Isis and Budapest-based Chinoin, and served as the company's first president of the board. The name Kaštel was taken from the castle where it began operations. The castle still stands today in the Drežnik–Hrnetić district of Karlovac; the company kept its name after moving production to Zagreb in 1927. It was only in 1941 that it was renamed PLIVA as an acronym for the State Institute for Production of Medicines and Vaccines.

Societies Janeček became a member of the Yugoslav (now Croatian) Academy of Sciences and Arts in 1882 and served as its president from 1921 to 1924.

Research and publications Janeček’s research spanned inorganic, analytical, physical and forensic chemistry, including water analysis and electrolysis, and he authored university textbooks and laboratory manuals. Overviews of Croatian chemistry place his work at the transition to industrial research in the interwar period and credit him with raising the level of pharmacy teaching and literature.

Personal life Janeček settled in Zagreb in the late 1870s. In 1900 he bought a property at Labudovac in the Plitvice Lakes area, where he arranged a small restaurant and guesthouse and planted trees. He had at least one child, Dragutin (Dragan) Janeček (1879–1914), a lawyer and Sokol leader. Janeček died in Zagreb on 8 September 1929. He is buried at Zagreb’s Mirogoj Cemetery (grave 32–I–17). A memorial plaque is dedicated to him at the Plitvice Lakes, where a stairway (Janeček’s Stairs) is named in his honour.
