From colleague and fellow scientist to close family friend and 'American granddad' to our children: That is how our relationship with Professor Roger Raufer evolved since Janosch first met him at a water cooler in the offices of the United Nations at Two UN Plaza some 23 years ago.
Now Roger has died, having lost his long battle against prostate cancer. We mourn the passing of a great teacher, scientist, engineer, mentor, and - to our daughters, Jana and myself - a very close family-friend, generous host, and regular guest.
Roger, you will be forever remembered for so many things: wit, warmth, wisdom, and an open heart and mind. Thank you for your friendship throughout all these years!
