Dear Petra, Christoph and Stephan,
I am very saddened and surprised by the news.
I send you a big hug and my deepest condolences.
And on the other hand I want to give you strength so that you can continue his legacy and be more united than ever for him.
I wish you peace.
I will always remember his kindness and cordiality and a very good trip we made several years ago to South America. I have good memories.
Lots of strength!
Ricardo
