Gisela Striker

Gisela Striker (born 1943) is Professor Emerita of Philosophy and Classics at Harvard University.

She was born and educated in Germany (with a doctorate in philosophy from the University of Göttingen). She taught philosophy at Göttingen from 1971–1986, at Columbia University from 1986–1989, and at Harvard from 1989–1997, and then was the sixth Laurence Professor of Ancient Philosophy at the University of Cambridge, England, until 2000, when she returned to Harvard.

Striker specializes in ancient philosophy, teaching Plato and Aristotle, as well as earlier and later Greek and Roman authors. She has written mostly on topics in Hellenistic philosophy (the epistemology and ethics of Stoics, Epicureans, and Skeptics) and on Aristotelian logic. Her work on Aristotle's logic builds on the tradition started in 1951 by Jan Lukasiewicz and reinvigorated in the early 1970s by John Corcoran and Timothy Smiley.
