Alexy studied law and philosophy at the University of Göttingen.
He is a professor at the University of Kiel and in 2002 he was appointed to the Academy of Sciences and Humanities at the University of Göttingen. In 2010 he was awarded the Order of Merit of the Federal Republic of Germany.
Alexy"s definition of law looks like a mix of Kelsen"s normativism (which was an influential version of legal positivism) and Radbruch"s legal naturalism (Alexy, 2002), but Alexy"s theory of argumentation (Alexy, 1983) puts him very close to legal interpretivism.
