The President of the German Research Foundation (DFG) is Honorary President of the Paul Ehrlich Foundation. The prize- giving ceremony is traditionally held every year on March 14, Paul Ehrlich’s birthday, in Frankfurt’s St. Paul’s church, a symbol of German democracy and liberty. The Foundation’s Scientific Council, whose members include internationally renowned Professor Dr. Thomas Boehm scientists, has the formidable task of selecting Max-Planck-Institute of Immunobiology the best of the excellent world-wide.

Many of the Paul Ehrlich and Ludwig Darmstaedter Prize winners have subsequently also received the Nobel Prize. With the Paul Ehrlich and Ludwig Darmstaedter Prize for Young Researchers, the Paul Ehrlich Foundation created an important instrument to encourage young gifted scientists.
