The only child of a wealthy German industrialist, Gustav Rau was born in 1922 in Stuttgart. At the age of forty, he decided to return to school to become a doctor while continuing to run the family business. Soon after graduating with a medical degree from Munich University in 1969, he sold the factories he inherited from his father and uncle to set up the Fondation Médicale du Docteur Rau. The foundation’s purpose was to diminish misery and disease in Third World countries through preventative practices and the distribution of medication.
