Abstract :
It is a privilege to be asked to recognize Professor Lotfi A. Zadeh on the occasion of his ninetieth birthday. As a math-ematician, electrical engineer and computer scientist, Lotfi s exceptional accomplishments in systems related research, practice, education and service are legendary; indeed, he has been well recognized for these accomplishments over a long and distinguished career that continues to this day. I shall therefore limit my remarks to personal interactions with this kind, thoughtful and gracious human being.
