It fills me with great sadness to learn that Don passed away. I well remember, in particular, the time when I worked with him on the PAS project. He was a noble person with a bright mind, convincing, but always ready to compromise in order to find acceptable solutions even in difficult situations. I very much enjoyed working with him and I consider myself fortunate to have him met.

Don was my mentor in the IEEE 802 standards arena. Whenever there was a question of procedure or strategy, Don always had a practical answer. He was the masteer of "electro-political engineering".
