Jeronim Tišljar was born in 1963 in Zagreb, Croatia. He gained his first experience in artistic modeling at the School of Applied Arts. He soon permanently focused on glass modeling, and went to the Academy of Applied Arts in Prague, Czech Republic, where he perfected his craftsmanship under the famous Professor Lybenski. Upon his return to Zagreb, Tišljar's concentration on form in his first projects developed in three main directions: glass as sculpture, glass as design and glass in interaction with architecture. Tišljar's works have become part of numerous private collections around the world from Prague and Chicago to Australia and New Zealand, owned by the French President Chirac as well as Thorvald Stoltenberg, Karl Schwartzenberg and Bill Clinton. Tišljar's stained glass windows adorn important public and sacral places such as the Croatian Parliament, the Croatian State Archives, the sanctuary of the Holy Mother of Freedom in Zagreb and many others.
Tišljar develops contemporary usable glass designs for widely known consignees such as the J.&L. Lobmeyr company from Vienna, Austria, and the Beranek glass factory. His unique pieces of craftwork have been ordered by the Croatian State Protocol as well as other national institutions.
