About Kuenzig Books

Kuenzig Books trades in Antiquarian Science, Technology, Engineering, and Mathematics material.  Subspecialties include early computing, chemistry, photography, the history of communication, and the discoveries that have impacted the way we live and work.  We buy and sell antique scientific instruments (microscopes, optics, slide rules, computers) both didactic and professional.   Add a broad range of documentary photography, ephemera, and eclectic material from other fields, and most visitors find something to interest them.  We welcome your visit electronically or by appointment.

Our History

Kuenzig Books was founded in 1996 by John F. Kuenzig.  Mr. Kuenzig earned a Computer Science and Electrical Engineering degree (Course 6-3) from the Massachusetts Institute of Technology (MIT). As co-founder(*) of Hammer Technology (now part of Empirix), he developed and built innovative test equipment for the telecommunications industry and was awarded a patent in speech recognition

Introduced to antiques and books at an early age, Mr. Kuenzig eventually took the opportunity to start a book business in 1996.  In his spare time, he enjoys hiking, tinkering with well made mechanical devices, and science fiction movies.

OUR CUSTOMERS and services

Our customers (both private and institutional) are the life blood of Kuenzig Books, and the reason we continue to succeed.  We strive to bring some of our newest acquisitions to bookfairs, and often place new material on our website first before uploading to other venues.

We put the customer in control of how much they want to know and how frequently.  Customers can add topic notifications for periodic (usually monthly) updates of new arrivals in their interest area(s).  They can add/update/remove topics anytime without calling. 

We also offer a separate e-list to hear about website sales, trade show announcements, and occasional catalogs. 

We won't harrass you - if anything we don't communicate frequently enough.

Our customer list includes multiple institutions, major private collectors, and thousands of occasional readers/buyers.  We do our best to be responsive to individual needs.

Professional Memberships

Kuenzig Books has been a member of The Antiquarian Bookseller's Association of America (ABAA) and the International League of Antiquarian Booksellers (ILAB) since 2008.  We are also members of the Southern New England Antiquarian Booksellers (SNEAB), the Independent Online Booksellers Association (IOBA), the Ephemera Society of America, and other professional trade organizations.
