Thank you Bernard and thank you Alex. One gets very few opportunities to thank those who have been formative influences on one’s career, and I appreciate the chance to do so. From the beginning my parents encouraged learning and an academic career. My father gave me an early lift into science, and I probably entered the inorganic realm largely to do something different than he did; he was a microbiologist. I also entered geology because I wanted to stay as far from computers as possible and to do my work in the field, but Indiana University field camp cured me of that illusion. At Indiana University I was taken under the wing of Case Klein, who taught me to finish what I started and got me excited about minerals.
