On top of what he achieved for conservation what a charming and elegant man Mark was. Having worked on Arabian oryx and on the Guidelines for re-introductions, I knew of Mark of course. I met him the first time at my first SSC Steering Committee meeting in 2001. I was intimidated to join such a Group of distinguished conservationists. Mark was one of those persons whose kindness and humility greatly facilitated my integration. I'll be thankfull for ever. The world needs more people like Mark.
