Dr. Jonathan Snellenburg joined Bonhams in New York as the Director of Fine Watches and Clocks in 2009.

His education started at Dartmouth College where he studied history and geology. He then received a PhD in Geochemistry from the State University of New York at Stony Brook. This led to a post-doctoral fellowship at the American Museum of Natural History in New York and later, a position as a staff gemologist for the Gemological Institute of America.

He then joined an international auction house at its new East Coast gallery as head of its Jewellery and Silver Departments. By the time he left in 1993, as Senior Vice President and Head of the Watch and Clock Department, he had organised sales in a variety of fields and catalogued numerous items including watches, clocks, jewellery, silver, furniture, scientific instruments and rare books. He then moved on to open his own business as a dealer, consultant and appraiser and was on the Board of Directors for the National Antique & Art Dealers Association of America.

Dr. Snellenburg is best known for his expertise in the field of antiquarian horology and has frequently lectured about the influence of science and technology on the European decorative arts from the 16th century to the present.

He has participated frequently as an appraiser on the PBS' "Antiques Roadshow®." He is also a member of the vetting committees for the Winter Antiques Show and the International Fine Art and Antique Dealers Show, held each year at the 7th Regiment Armoury in New York City.
