I received my doctorate from the University of Vienna in 1910.

I studied at a grammar school and later at the University of Vienna in the Faculty of Medicine.

After the first exams, I switched to the Faculty of Philosophy and studied Zoology in Munich and Vienna.

I have been a Professor Emeritus since 1958, and have continued my scientific studies.
