Social responsibility was always extremely important to Prof. Dr. h.c. Viktor Dulger and the rest of his family. For decades the family has supported numerous social establishments and institutions working in the areas of technology and science, as well as groups and charitable projects such as the German Centre for Music Therapy Research (known since 1997 as the Viktor Dulger Institute), Heidelberg University, foundation marking the 600th anniversary of Heidelberg University and numerous associations such as the Heidelberger Hauspflegeverein (local home care association) and sports clubs. Every year the Viktor-und-Sigrid-Dulger-Foundation awards prizes for the best dissertation in the field of environmental technology, outstanding work by early career researchers or the best graduates.
