Honours

At the occasion of his 80th birthday the Swiss Geological Society honoured Peter A. Ziegler with a symposium on the theme “Deep Earth - from Crust to Core”, held in Lugano, November 23d, 2008.
Peter A. Ziegler is still active and regularly contributes to geosciences by reviewing papers and research proposals. It is the unending support by his wife Yvonne that has shaped his career. Hats off to her!
