William Hanneman, a Gemologist Who Made His Field Affordable, Dies at 93

Post by PinkDiamond »

I know Bill was very old, but this is still terribly sad that we lost such a brilliant gemologist, author and inventor. Many years ago I knew Bill from other forums, and bought quite a few of the gemology tools he invented, even being the proud owner of his last bench model of The Jeweler's Eye, as well as quite of few of his books. He was so cordial and gracious to me when I called him out of the blue one day and spoke with him, which was when I bought most of the equipment from him, and it was during that conversation that he decided to sell me his last Jeweler's Eye, so I'm really sad that the industry has lost a truly great man with a kind soul. There's a link in the article to his online obituary if anyone wants to read it. My heart goes out to his children. R.I.P. Dr. Bill. :cry:

Dr. William Hanneman, known for his many contributions to gemology including creating a line of affordable instruments, died last month at the age of 93. He is pictured here at left with his friend Alan Hodgkinson, also an award-winning gemologist.

"Monterey, Calif.—Dr. Walter William Hanneman, the gemologist known for sharing his knowledge and helping make gemology accessible to all, died Dec. 12 at his home in California.

He was 93.

Hanneman, who was known as Dr. Bill, received his undergraduate degree from the University of Illinois, Urbana-Champaign and his Ph.D. in organic chemistry at the University of Nebraska, Lincoln.

He then worked as a research analytical chemist for several major corporations, including the DuPont Research Lab, the Standard Oil/Chevron Refiner, and the Kaiser Center for Technology.

His father was an avid lapidarist and introduced Hanneman to gems and minerals at a young age, kicking off a lifelong hobby of gemology, according to his online obituary.

Hanneman’s early endeavors in education would later lead to a mission to make gemology affordable to anyone who was interested.

In the mid-1960s, he decided he wanted to learn gemstone identification.

But, after being told about the prerequisite classes and their associated costs, Hanneman rejected that path, opting instead to teach himself through popular books on the topic and his advanced degrees in chemistry.

He felt his 40 years of experience qualified him to examine gemology from perspectives far different from those of the traditional industry schools and called himself the world’s foremost S.O.G.—Self Ordained Gemologist.

As a champion of aspiring gemological students, Hanneman believed anyone with an interest in learning about gems should have the opportunity to do so.

Using his analytical mind and chemistry background, he set out to create an alternative and affordable path to gem identification, creating his own line of instruments under his name, Hanneman Gemological Instruments.

These instruments are still used worldwide.

Hanneman also authored numerous articles and books in his efforts to make gemological information accessible, including “Pragmatic Spectroscopy for Gemologists,” “Diamond Cut Grading Simplified,” “Naming Gem Garnets,” and his signature book, “Guide to Affordable Gemology.”

He also shared his knowledge openly through lectures, seminars and workshops, inspiring generations of gemologists and gemological enthusiasts.

In a Facebook post, gemologist and author Antoinette Matlins called him a “brilliant gemologist, a man who gladly shared of his knowledge and talent, a warm supporter of the Accredited Gemologists Association—and how many of us have the little practical gem tools he created and gave to AGA members—and simply a wonderful, talented, loving, thoughtful man who loved life and did what he loved throughout his own.”

The AGA honored Hanneman in 2018 with its Antonio C. Bonanno Award for Excellence in Gemology, and the International Society of Appraisers gave him its Industry Service Award for contributing to the advancement of the appraisal profession.

“The AGA was deeply saddened to hear of the passing of Dr. William Hanneman, recipient of the Antonio C. Bonanno Award for Excellence in Gemology,” Donna Hawrelko, former AGA president and close friend of Hanneman, said on behalf of the AGA in a statement sent to National Jeweler.

“Dr. Bill, as he was affectionately known, was a generous, brilliant scientist, author, and inventor of affordable equipment for the gemmologist. (He) was always willing to share his vast knowledge with students, gemologists, and scientists alike. He will be deeply missed by everyone who had the privilege of knowing him.”

Outside of gemology, Hanneman was an avid fly fisherman, an area in which he also made contributions.

He created the “Hanneman Common Cents System,” an objective system for the relative measurement of rod action, power, and frequency, which was published in RodMaker Magazine and Tenkara Angler magazine.

He also wrote a book called “What Trout Actually See.”
