The Whitehead Research Project sadly reports the death of Reiner Wiehl, philosopher and Whitehead expert at the University of Heidelberg. Professor Wiehl died on December 30, 2010, at the age of 81. He served as Professor of Philosophy at the University of Heidelberg since 1976, where lectured and wrote on Kant, Whitehead, and existentialism. Together with Friedrich Rapp, he co-edited the volume Whitehead's Metaphysics of Creativity. As one of the foremost European Whitehead experts, Professor Wiehl will be greatly missed.
