I've not other words... Shocked and saddened...
Here, apart from our common passion, friendships are created and I think that Ralph was, for many of us as for me, a very pleasant and always positive person: a friend...
My condolences to his family.
As we republicans say here, May the earth be kind to you, comrade!!!.
I rarely met him, but I have been reviewing his works and he has left us a great legacy.
