Abstract
“The conception of the First International Congress of Acarology originated one evening during an informal discussion in the library of the Zoological Institute at the University of Vienna in August 1960. This simple beginning during the course of the convened XIth International Congress of Entomology initiated the general plans. Subsequent discussions among those acarologists present resulted in the establishment of an organizing committee which was charged to consider the feasibility of an international meeting and to make positive arrangements.
