In 1905 he became an assistant in the Crustacea, Arachnoidea, and Myriapoda collection of the museum. On several excursions to Macedonia, Slovenia, and Croatia he collected myriapods, which he afterwards examined in addition to other collections from all over the world. In between Attems was appointed curator of the Evertebrata-Varia collection and spent the summer of 1911 in Roscoff, France, studying polychaetes. In the same year he married Emma von Montbach.
