In the 1950s, the German-born Boehm starred alongside Romy Schneider in the television series “Sissi,” playing Emperor Franz Joseph of Austria. He later appeared in Michael Powell’s 1960 thriller “Peeping Tom” and in movies directed by Rainer Werner Fassbinder.
In 1981, angered at the indifference of people in rich countries to poverty in Africa, he founded Menschen fuer Menschen. Its projects in Ethiopia have included efforts to build schools and hospitals. The group is now led by Boehm’s wife, Almaz.
