Karl-Otto Apel (1922-2017)
The eminent German philosopher Karl-Otto Apel died on May 15, 2017. Apel was especially known for his "transcendental pragmatics", which included a Peirce-inspired view of language and influenced e.g. Jürgen Habermas. Apel served as president of the Peirce Society and made significant contributions to Peirce scholarship; his Der Denkweg von Charles Sanders Peirce: Eine Einführung in den amerikanischen Pragmatismus (1967) is a milestone in European Peirce and pragmatism research.
