Josef Marx began to issue an annual magazine entitled Deutsch Ungarisch Familien Kalendar in 1932 as a method to keep German immigrants from the former Austro-Hungarian Empire in touch with one another in North America.

He used the designation Deutsch Ungarisch because that was the nomenclature used by his fellow countrymen who were unaware of the designation Danube Swabians. The publication would last until the early 1950's which closely paralleled Josef Marx’s death. In addition to the calendar itself he left behind his subscription lists with the names and address of his subscribers which also included information as to their home communities prior to their emigration.
