Vilko Žiljak, scientist and innovator known for kuna design, dies

Vilko Žiljak, a distinguished Croatian scientist, innovator, and professor emeritus, has died at the age of 80. Žiljak was recognized as a pioneer in computer graphics, mathematical modeling, and graphic technology in Croatia. His passing was announced by the University of Zagreb, where he held a professorship.

Beyond his academic contributions, Žiljak was widely known as the co-author of the design for the Croatian kuna currency. He notably chose not to accept a fee for this significant contribution to the nation's identity. He also played a role in shaping the initial documents of the Republic of Croatia.

Žiljak's innovative spirit extended to his development of INFRAREDESIGN, or infrared design, and InfraredArt. This method allows for the printing of hidden visual information within the infrared spectrum, a technique applied in the security printing of banknotes, documents, and artworks. His expertise was also sought in the design of large industrial systems, including projects at Koksara in Luka Bakar, Luka Rijeka, and JANAF.

His career was marked by numerous accolades, including the State Award for Science in 2010 and the "Nikola Tesla" award for the best Croatian innovator in 2009. He also received multiple awards at international innovation exhibitions. Outside his scientific pursuits, Žiljak was active in sports, having been a sailor, a sports pilot, and the president of the Croatian Bobsleigh Federation. The University of Zagreb remembered him as a "visionary who combined exact science and art," leaving an indelible mark on Croatian science, technology, and art.
