Klaus-Otto Elsser

I was just thinking to Klaus Otto. We met us in France in Tignes a long long time ago. We spent nice time. He was with a friend Friedemann. Both went to my wedding in France. Often I thought to meet then again but time spent. I’m sad to know he leave us 2 years ago. If you read that and if you know email of Friedemann, please send me. I pray for Klaus. Regards Patrick
