Antique mechanical collection, including Millionaire, TIM (Time Is Money), etc.

[Seth Lipkin]

Hello all,

I have a collection of mechanical calculators that includes:
* One "The Millionaire" calculator

* One Ludwig Spitz & Co TIM (TIME IS MONEY) calculator

* A number of Goldman's "Arithstyle" calculators

* Several Remington accounting machines

* One Mathematon calculator

* Another dozen or so accounting machines of various ages (1920-30 to 1970, probably)

I'm looking for a good home for all of these. What recommendations do you have for making these visible to either private collectors or museums? 

Best regards,

Seth Lipkin

I was in the same situation as you 3 years ago. I was advised to put together a spreadsheet of make model serial number and condition and post it on Forum website. Mine was approximately 160 calculators and adding machines. It was very successful as I received offers from United States, Munich Germany, Paris France, and finally one person bought the remainder of my entire collection. I suggest you consider doing the same.

Excellent suggestion, thank you!

I am new to this type of collecting. I just purchased an old Arithmometer and Johann Schuster calculator. Are there a set of professional dealers or auctioneers that specialize in very old calculators, even the type of reproductions that are often seen in European museums? I have a website dedicated to clocks, but a small entry is here for my new interest: http://www.my-time-machines.net/other_horological_examples.htm. I have joined the SIS -Scientific Instrument Society. Any suggestions on how I might learn more?

Hi Mark, and welcome. Your chosen field of collecting is quite ambitious - there aren't many originals or reproductions around from that era. Specialized dealers or auction houses - apart from Bonhams and Christies, who seem to have taken a serious interest in the history of informatics lately, there's Breker in Germany. In terms of associations, you could do worse than joining the International Forum for Historical Office equipment, ifhb.de ; they have a dedicated website. It is a mainly German association, but they do their best in recent years (and succeed) to provide an english translation for every publication. There is also a forum on the website.

Kind regards,

Hi Cris,

 

I will contact the ifhb.de, again as a way to learn. Yes, my collecting has always been a bit “out there”. https://youtu.be/iALgZf3RB7s.

 

Best regards,

Mark

Hi Mark,

Your YouTube channel is amazing!  I look forward to seeing more of your calculating machine collection as it evolves.

If you haven't already been, I would suggest a visit to the Arithmeum in Bonn, Germany, https://www.arithmeum.uni-bonn.de/en.html.  They have an impressive collection with a primary focus on calculators, including several exquisite reproductions of very early machines by Ulrich Wolff.

There is also a very comprehensive reference work by Herbert Bruderer, "Milestones in Analog and Digital Computing" https://link.springer.com/book/10.1007/978-3-030-40974-6  - I don't have a copy (yet) but the table of contents looks to be very detailed and the reviews of the book have been very good.

Hi Cris,

 

I have two books by the Bonn Arithmeum, the Arithmaurel as well as their museum catalog. I will have to visit one day. Yes the Bruder book looks interesting too. I wonder if Mr. Wolff could be commissioned to make another reproduction?

Nice to see your name pop up here.  I'm familiar with you from the clock realm, followed you for a few years ,especially the Astronomical Skeleton clock (https://www.youtube.com/watch?v=iALgZf3RB7s&t=583s).  Good luck in building your collection.  It is destined to be world class -
