Ivan Regen

Ivan Regen was a Slovenian biologist, best known for his studies in the field of bioacoustics.

Regen was born in the hamlet of Laje and became interested in insect sounds as a child. His family couldnt afford to pay for his schooling, so he studied first at the local seminary for which he received a scholarship, and slowly saved enough funds for the tuition fee in Vienna. There he studied natural history at the University of Vienna under the tutorship of Grobben, Exner and Claus. He received his doctorate in 1897 and began to work as a gymnasium professor, first in Vienna, and later in Hranice . At last he was transferred back to a gymnasium in Vienna after a recommendation from Exner and worked there until his retirement in 1918.
