Who they were
Ivan Merz was born at Banja Luka on 16 December 1896. After a brief time at the military academy of Wiener Neustadt he enrolled at the University of Vienna in 1915, hoping to teach the young of Bosnia like his own teacher, who had helped him discover the riches of the Catholic faith.
The horrors of the war deepened his faith, and he resolved to strive with all his strength for Christian perfection. A scholar, teacher and committed Catholic layman, he gave the young a shining example. He died in Zagreb on 10 May 1928, aged 32, with a genuine reputation for holiness.
