Zvonimir Janko, is a prominent Croatian mathematician, professor emeritus of the University of Heidelberg. He was born on July 26, 1932 in Bjelovar, where he attended elementary school and gymnasium. He graduated in 1956 from the Faculty of Science in Zagreb. He was expelled from the University for two years for laying a wreath at the grave of Dr. Ante Starčević. In the meantime, he worked at the Gymnasium in Široki Brijeg (Bosnia and Herzegovina, 1956-1961). He received his Doctorate in Mathematics from the Faculty of Science in Zagreb in 1961.

From 1972 until his retirement (2000), he was a full professor at Heidelberg.
Zvonimir Janko is known for his achievements in the theory of finite groups. The most significant are the discoveries of new sporadic simple groups, now known as “Janko’s groups”. He also left an indelible mark on the projective plane theory and designs.
Professor Zvonimir Janko participated in postgraduate teaching at the Mathematical Department of the Faculty of Science, University of Zagreb, gave a series of lectures in Zagreb, Split and Mostar. He is an associate and mentor to many Croatian and foreign mathematicians. During his work at Heidelberg, his help to Croatia in various forms was noted.
