As announced at the RDG Woodwinds site, Robert D. Gilbert died on August 2.
Mr. Gilbert is responsible for my owning a lovely Rigoutaut English horn. In my freshman year of college my very horrendous EH was stolen from my dorm room and Mr. Gilbert sent me a Rigotaut saying he had the perfect instrument for me. I’ve had it ever since. And I love it.
Here is an RDG interview, with Nora Post.
