Aside from teaching younger students, one of his tasks was to organize the extensive collections his mentor had purchased, with a view to setting up a museum. After the latter's 1892 death, he was selected as a substitute professor.[1] In 1890, he was hired by his former high school, and in 1891, by the Iași commercial school.[2] In 1895, he enrolled in the University of Vienna, where his professors included Eduard Suess and Albrecht Penck.
