Celebration in honour of Prof. Dr. Claus F. Claussen’s 60th. anniversary
Abstract
It has been a great privilege for me having been selected by you to give evidence of the affection that my wife Julia and I feel for you. Also, the fact that you have always been able to share your knowledge, your ability, your time and your talent with us on top of the hospitality and friendship that you and Erika have always offered us has been highly appreciated by us.
We can’t honour our teacher without mentioning a short outline of his life
