Whatever part of the World you come from, when you come to Rijeka you came to the heart of Europe. Rijeka is waiting for you with the scent of its sea and the hospitality of its people. Rijeka is a town of unusual, turbulent and intersected history. At the end of the IX Century the area of Rijeka was one of the most powerful industrial zones in Europe. Prof. Eugen Cerkovnikov, Ph. D., a much-respected chemist, first Head of the Department for Chemistry and Biochemistry on the then newly established Medical School in Rijeka, launched the initiative to form a branch-office of the Croatian Chemist Society in Rijeka. On 18 January, 1958 in the Big Classroom of the Medical School in Rijeka the Founding Assembly was held, and many respected scientists of that period were present. In 1960, the Rijeka branch-office of the Croatian Chemist Society merged with the Society of Chemists and Technologists and in 1973 the Biochemists section joined. In the five decades of its existence, the love towards chemistry, biochemistry, molecular biology, technology and chemical engineering, the love towards the basis of natural sciences and the wish to educate new, progressive generations formed the mission of the Society. The Society does not want to be closed in a guild organisation; its aim is to open its doors towards all those striving to progress. Former presidents of the Society were: Eugen Cerkovnikov (1958-1974), Marijan Kolombo (1974-1980), Josip Šilipeter (1980-1984), Marinko Oršia (1984-1996) i Nikola Bla?evia (1996-); and each one of them marked his era. Transitional circumstances have shut down forever many, until recently, extremely powerful industries in Rijeka. Today, Rijeka is searching for new paths, and we believe that our Society will continue to work on and give its contribution to this search.
