Stunningly Intricate: Curta Mechanical Calculator
71What if Babbage's Difference Engine spawned a "laptop"?
It's hard to find more desirable and satisfying (in a tactile sort of way) mechanical fetish item from the age of early computing...
For years Curta calculators enjoyed a cult status among collectors, and as recently as in 2003 they were featured in William Gibson's "Pattern Recognition" book. However, I daresay, not featured enough. This marvel of mechanical engineering should be given more exposure, especially given the bizarre and spooky circumstances of its origin.
- Entirely mechanical, no electricity or batteries involved.
- Designed by Curt Herzstark in 1938 and perfected inside a concentration camp.- Considered to be the most efficient portable calculator (until electronic calculators came in the 70s)- Simply a thing of beauty, stunning piece of engineering art.
First, you gotta feel it in your hand... It purrs.
Take this glorified pepper-grinder shape in your hand, set the multiple sliders and turn the computing handle - and this groovy gadget starts to make a wizzing, almost musical sound. There is no electricity, wires, or batteries! Just a sophisticated package of miniature cogs and parts, that is a joy to disassemble and put together again...
Generally an arithmometer with multiple cogs and stepped drum mechanism, there is however a lot to disassemble. See a poster of all the parts inside, available for purchase on this site (the most comprehensive I could find on the topic):
Perfected in a concentration camp, as a gift to Hitler!
Probably the weirdest story of invention ever told:Working on this device saved the life of its inventor, and could've put "the ultimate computing weapon" into the hands of every Nazi army engineer... pretty much the stuff of nightmares."Herzstark was a prisoner at Buchenwald but the camp leaders were aware of his work and encouraged it. They apparently wanted to give the invention to the Fuehrer as a victory gift at the end of the war! Herzstark was given a drawing board and worked on the design day and night. The camp was liberated in April, 1945 by the Americans. Herzstark survived as did his revolutionary concept for a miniature calculator." (source: Bruce Flamm)Disassembly of a mechanical marvel: It has 605 individual parts!
It must be very therapeutic and calming experience (you know how in the army they make soldiers to take apart and clean their guns, a repetitive ritual that calms down and reduces the chances of a shooting spree - I am being sarcastic here) Well, the antique calculator collectors are a cool bunch and not easily given to any angst - but they too, gladly, would spend hours taking apart this little calculating device. The best page showing the disassembly and wonderful innards of this device are located here. Here are only a few steps, highlighting the joy of this process:
Meanwhile, Russians engineers were using their own mechanical creations:
"The Iron Felix", Stalin-era Calculator
Check out this Russian model of arithmometer, ominously named "Felix" (after Felix Dzerzhiski, founder of Soviet KGB) It was based on 1914 St.Petersburg's Odner-Hill company device, shown on the bottom.
The first such device was made in 1931 and provided the Soviet bureaucracy and terror machine with much needed ways to account for things, including facilitating GULAG operations. Thus, they earned the right to be called "The Iron Felix" - haunted and heavy mechanisms:
The original pre-Revolution Odner:
We will definitely continue the theme of mechanical calculators, so let us know of the "pride and joy" of your collection, if you have it!
To sum it up: If Charles Babbage could hire Curt Herzstark to develop a portable calculating machine... we would have awesome mechanical personal computers - fashioned in brass, or minimalist black, with the label "Designed by Babbage in California, assembled in China".

no way, thats amazing, im almost half way with making my calculator
Awesome article, a very interesting piece of technology.
It's a nifty device! Good hub.
I calculated huge construction jobs for years on just such crude machines.
i dont think people appriciate this its such an amazing device this man is amazing
What would Pascal say if he read this article. Oh I know, "Too Cool!"
What w neat writeup! I found this via Stumble and it tickled the memory bank. These were still in use by rally navigators in the seventies when I was an SCCA member. I had forgotten about them completely until I found this. Thanks!
Very, very interesting - never knew something like this existed! It really does look like a pepper mill!
What a fantastic concept, a mechanical calculator! This is a completely new one on me. I remember using slide rules at school, but this looks like a lot more fun. Thanks for posting this informative hub.
Intricate very cool hub.
Fabulous story around an invention. Blogging this on over to my blog the soul calendar as this is definitely a hub to fit both the science and oddity niches, thank you, really enjoyed it!
Absolutely fascinating Hub topic and cool video. Your amusement park hub is way to macabre for me. Have a happy day. Thanks for following on twitter. http:www.twitter.com/debweb0
