Calculator

Webster’s Revised Unabridged Dictionary, 1913
(Cal "cu*la*tor) n. [L.: cf. F. calculateur.] One who computes or reckons: one who estimates or considers the force and effect of causes, with a view to form a correct estimate of the effects.

This site is dedicated to the late Tadeusz Kabzinski, a teacher and a friend who brought to life most of these calculators.

I guess I got a calculator bug a few years ago. Over the years this bug became a monster, slowly it took over from one book shelve, the whole bookcase, than two, three… Now it is taking over one of the bedrooms and part of the hallway, and it is still creeping…

When I tried to create the presentation of my collection, I came to the conclusion that the most logical way would be to follow THE BOOK – The Calculating Machines (Rechenmaschinen) by Ernst Martin (1925). On the following pages you will find all my collection (OK, almost all). Click on the machine below to see the full collection or go down to view any particular machine.

I precede the machines from the collection with corresponding pages from Martin. Some of the computing devices were not in Martin, so I put them towards the end. You will find a few very interesting pieces there.

Martin organized his book by the first production year of each manufacturer.

After I did it all I came to the conclusion that it would be very interesting to create an annotated and illustrated book by Martin on the WEB. This project did not go anywhere till Herbert Schneemann looked at my website. He wrote that he would be interested in helping building the site based on THE BOOK. He did not know then that it would be me rather helping him in this undertaking. We got permission from MIT Press to put Martin’s book on our site www.rechenmaschinen-illustrated.com. If you want to help in building this site please email me: walter@szrek.com or Herbert: Herbert.Schneemann@t-online.de .

Ernst Martin book “Calculating Machines” you can find at www.rechenmaschinen-illustrated.com. This site adds value to Martin’s book by adding pictures, articles and some other information.

Visit hpmuseum site to find out how these machines work.

Visit “Original Documents on the History of Calculators” to find documents related to calculating devices.

Visit Michel Bardel's web site to see the list of thousands of calculators. It is invaluable source of the information.

Josef Balsach created a very beautiful book about the calculating devices. You can find it on personal.telefonica.terra.es/web/calculating/. You will find pictures and description of many very interesting devices there.

There is a new web site www.rechnerlexikon.de, in German, there is also English navigation there. They are trying to create as big catalogue of machine as they can. The site has interesting articles and pointers to the patents of many different machines.

Another very interesting place is Reinhard Atzbach’s web site. Reinhard has a very interesting and educative way to present different machines. It is in German. I was using http://world.altavista.com/ to translate these pages. You can also use google translation features or their toolbar.

I am looking for the information about Stern, Staffel and Slonimski machines. If you know about any surviving ones or have their pictures please email.

Credits:

· All these machines are in my collection except Staffel, which belongs to the Museum of Science and Technology in Warsaw, Poland. I do not own the portrait of Abraham Stern with his machine either.

· THANKS to my wife Irena for understanding…

· Thanks to my daughter Monika for consulting on how to do WEB pages.

· I am most grateful to Mr Tadeusz Kabzinski. He was a fantastic person and a mechanical genius. He loved the old office equipment which he has been repairing for the last 57 years in his own small repair shop in Warsaw, Poland. He offered me his friendship, and he brought many of my machines back to life. I learned a lot of things from him. I guess I would never have gotten this far with the collection if not for his wonderful personality and his incredible skills.

· For the idea of how to set up the website, I am especially grateful to a very good friend of mine and a great artist – Piotr Kaczmarek. He also designed (and coded) our professional website www.szrek.com.

· Over the years I learned a lot from my fellow collectors. I am especially grateful to Thorsten Hampel who taught me a lot of things. He has a beautiful collection. I hope I can see it one day in person.

· Ernst Martin’s book is available as a both Xerox copy and Adobe Acrobat file (.pdf) from MIT bookstore. It is the best and the most interesting book on this subject.

· A lot of information about production years for different machines, and a beautiful diagram about the evolution of the machines come from Martin Reese book. This book is full of information. Unfortunately you need to know German to understand it all. I do not know German ;(((

· I learned of the article about the Staffel machine from Timo Leipala, who also provided me with a lot of other invaluable information.

· Serial numbers for the Facit machines I found on Facit page. You will find a lot of interesting information there. Look at their album. It is FANTASTIC!!! You can find a lot of information about Facit calculators in Christopher Nöring page.

· Victor machine’s instructions I found in the jmgoldman collection. I always enjoy looking at these toys.

· Webb patent drawings I found on the WEB. Unfortunately I do not remember where ;((((

· List of Early Brunsvigas, which is extremely interesting, I received it initially from one of the fellow collectors. The complete list I received from Freddy Haeghens. Internationales Forum Historische Bürowelt compiled this list. In April 2004 IFHB published the most complete book/catalogue of calculating machines.

· Portrait by Antoni Blank of Abraham Stern’s comes from the book “Zydzi Polscy” (Polish Jews).

· Almost all of the photos were taken by me. In a few cases I used pictures of my machines from ebay.

[1] Brunsviga B serial 980 is 894-1895 model. This machine is a so called Schuster machine. One can recognize it from two holes after Schuster logo (with hand) that used to be around Brunsviga logo. Schuster was selling these machines. This machine has clearing mechanism and decimal points. This mechanism was added later. I suspect circa 1910-1920. Unfortunately patent information was painted over at this time. All early Brunsviga models had patent information on the left side. The fewer patents - the more valuable for the collector (except of the number 0 as in my case ;(((). Brunsviga with serial number 220 had 3 patent numbers. This model still did not have a carry mechanism above 10-th position. This mechanism was introduced around 1900. The other model with serial no 6846 has it. The earliest known example of Brunsviga B with a short crank and serial no 73 was sold at Breker auction in November 2002 for Euro 6,000. This model had a short crank. There were only 600 of those made. Short crank Brunsviga looks very similar to Odhner Arithmometer with serial number 1341.

[2] Brunsviga was selling its calculators in France under the name La Rapide and Brunsvigula. This model is from 1898.

[3] Brunsviga B ser 11364 has already a clearing butterfly on the left side for the setting register (levers). This clearing mechanism was introduced by an engineer Trinks.

[4] Brunsviga A ser 1725 is an 1896-1897 model with 18 digits precision. This model is quite rare. It still does not have a carry above 10-th position.

[5] Brunsviga M is a miniature version of Brunsviga B

[6] Brunsviga MA is a miniature versio
