Gustav Radbruch, born November 21, 1878 in Lübeck; died November 23, 1949 in Heidelberg, was a German law professor, most famous for the Radbruch'sche Formel (Radbruch's formula) which states that where statutory law is intolerably incompatible with the requirements of justice, statutory law must be disregarded in justice's favour. He developed this principle in response to the Nazi era, and the principle has been accepted by Germany's Federal Constitutional Court in a variety of cases.
