Having, as always, a good time with Klaus, here during HPLC 2006 conference in San Francisco. Klaus was generous enough to sponsor the annual Csabaites Meeting at Carnelian Room, 52 stories above San Francisco in the Bank of America building. Thank you, Klaus, for yet another sophisticated night out!
with Imre and Markus Molnár @Yardley Inn, Nov. 2015. Thank you for being with us whenever we made it to the US or you visited your home town of Hamburg, Germany. Thanks for the decades of your dear friendship, for your interest in our lives, your affection and great sense of humor. We miss you!
