Rainer Gross Prize

Hildegard Grunow Foundation

Alemania, 2012

The Rainer Gross Award: Recent Innovations in Nutrition and Health in Developing Societies was created by the Hildegard Grunow Foundation to honour the memory of the late Dr. Rainer Gross (http://www.unicef.org/people/people_36064.html) and memorialise his unique approach to innovation in concepts and research in critical — but novel — areas of inquiry, with a view to better the nutrition and health of the less fortunate.
