Last but not least, I shall tell you the true story about when we learned that Stanley isanenthusiasticenvironmentalist, inthebestsenseoftheword. About25yearsago, in Stockholm, Stanley, my wife and I strolled in the King's Garden. Its elmtrees were full 7 J. Seckbach et al. (eds. ), Life in the Universe,7-8. C 2004 Kluwer Academic Publishers. Printed in the Netherlands. 8 of young people who, some even spending nights in the trees, prevented the authorities from removing the elmtrees, by ax and saw. Also Stanley signed a petition to save the elmtrees-andtheyweresaved! Stanley, I believe that your greatness as a scientist and as a friend must be linked to the many facets of your wonderful personality. We much look forward to your lecture.
