It is a great privilege and honor to introduce Alexandra Navrotsky as the recipient of the 2006 Harry H. Hess Medal. She is an outstanding scientist who has made important contributions to our understanding of minerals and other materials through a wide range of theoretical and experimental applications of thermodynamics. She was trained as a physical chemist and originally approached oxide chemistry through a materials perspective. However, her interests broadened and she became known as a leading authority in a wide range of subjects from chemistry through materials science to the geosciences. She held faculty positions at Arizona State University (Tempe) and Princeton University (N.J.) and is now at the University of California, Davis.
