35.1BarthMemoriam FINAL IN MEMORIAM Else Margarete Barth (1928-2015) Born in Strinda, Norway, Else Barth studied philosophy, phys- ics, and mathematics in Trondheim, Oslo (with Arne Naess), and Amsterdam (with Evert Willem Beth). In 1971 she obtained a Ph.D from Leiden University, supervised by Gabriël Nuchelmans. From 1971 to 1977 she was a lector in logic at Utrecht University and from 1977 to 1993 a professor in analyt- ic philosophy at the University of Groningen. Her main contributions to philosophy are in argumentation theory, dialogue logic, formal semantics, and in the logical anal- ysis of authoritarianism. She was an outspoken advocate of women's rights in academia. Her principal publications include The Logic of the Articles in Traditional Philosophy (1974), From Axiom to Dialogue (1982, with Erik Krabbe), Problems, Functions and Semantic Roles (1986, with Rob Wiche), Women Philosophers: A Bibliography of Books (1992), and A Nazi Inte- rior: Quisling's Hidden Philosophy (2003). She influenced Frans van Eemeren and Rob Grootendorst as they developed their pragma-dialectical approach to argumentation. A Fest- schrift in her honour, Empirical Logic and Public Debate (edit- ed by E.C.W. Krabbe, R.J. Dalitz and P.A. Smit) appeared in 1993. An advocate of an “empiricist cultural reorientation” in logic, Barth wanted logic to contribute to a systematic “under- standing and subsequent improvement of the models of thought and argument that are found in the polis.” In this respect she in- fluenced such informal logic theorists as Maurice Finocchiaro and Ralph Johnson. Else Barth was a friend of informal logic. In 1993 she ac- cepted a Visiting Research Fellowship from the University of Windsor’s Humanities Research Group, and she served on the Editorial Board of Informal Logic from 1989 until 2007. We benefited from her academic advice as well as her warm friend- ship. – The Editors, with a contribution from A.M. Tamminga
