Hermann Bollé (18 September 1845 – 17 April 1926) was an Austro-Hungarian architect of Franco-German origin who practiced in Croatia (Zagreb and Slavonia), as well as in Serbia.
After attending a vocational school where he studied civil engineering, he worked in the architectural studios of Heinrich Wiethase, where he was involved in projects for churches and other religious buildings.
Beginning in 1872, he studied at the Academy of Fine Arts Vienna while working in the offices of well-known cathedral architect Friedrich von Schmidt.
During 1875–76, he lived in Italy where he met Bishop Josip Juraj Strossmayer and the painter Izidor Kršnjavi.
In 1876, he went to Đakovo, where he joined Friedrich von Schmidt to complete construction of the Cathedral of St.Peter and St.Paul, begun by architect Carl Roesner, who had died in 1869.
