About Kuenzig Books

Based in Topsfield, Massachusetts, Kuenzig Books buys and sells rare and/or interesting items in many fields with a focus on 19th and 20th century Science, Technology, and Engineering. We are particularly interested in the History of Computing, and the speed with which the technological innovations of the 20th century have impacted the way we live. You'll discover some depth in Physics, Mathematics, Nobel Prize authors, Medicine, Scientific Instruments, and Chemistry.

We continue to deal in scientific artifacts (microscopes, philosophical apparatus, early motors, early computers, calculators, slide rules, etc) and you'll find them mixed in with our books at tradeshows. Please inquire if you are interested in artifacts as few are listed on our website.

We also buy and sell ephemera, photography, manuscript material, diaries, letter archives, and business archives in any field. If it tells a strong story, we're interested.

Mr. Kuenzig has a patent in speech recognition and was co-founder with Steve Gladstone of Hammer Technology (which built test equipment for the telecommunications industry). John enjoys hiking, tinkering with well made mechanical devices, and science fiction movies.
