W. William Hanneman

Dr Bill Hanneman was an inspiration to gemologists everywhere. His inventions and ideas have made gemmology easier for so many. He was a problem solver, was always willing to listen and never hesitated to share his skills and opinions. He could walk the floor in Tucson and was stopped by almost everyone as he made his way. He will be missed.

What an awesome guy that was laid back and always went with the flow. He was smarter than many of us put together and taught a lot of people throughout his life with all of his inventions, books, and mentorship. He will forever be missed! I’m glad you got to be a part of mine and your great grandchildren’s lives. RIP!

Bill was a very kind and gentle soul. A man convinced that knowledge that is not shared is knowledge that is lost. I will cherish the memories of the conversations we had when he was living up here Washington State. Ever the humble man, but his imprint on gemology has been HUGE. Bill, you will be missed by all of us who continue to use your instruments today. May every cast of your fly reveal a trout on the line. Until we meet again dear friend, farwell.

Dr. H was such an incredible contributor to the gem & mineral sciences and careers. I had the pleasure of meeting him several times over the years at the NAJA ACE-It Conferences. He was a great man and will be missed. To his family, my heart aches for your loss. Peace and comfort be with you.

My sincere condolences to his family and his larger gemological family. Losing such a pillar will be greatly felt when we return back to Tucson. Hana Merk

Bill will be missed. Thanks for the inspiration and knowledge.
