There's a very lively startup scene in Berlin, but no-one in that scene seems to know that the world's first digital computer was built in Berlin. There's an obscure and easy to miss sign ( https://en.wikipedia.org/wiki/Konrad_Zuse#/media/File:2007-0... ) on the house he lived in while working on it, and another sign at the technical university, but that's about it. No big festivities in his name, no commemorations,…

It probably has to do with world war 2. It wasn't regular Germany where it was built in. It was in a Germany that was controlled by an insane lunatic.

Many people i know in Berlin know that one of the first mechanical calculators is in the technical museum Berlin, but those people don’t know about concepts like turing-equivalent, so they call it a Computer.

Many great inventions have a nationalist folklore surrounding it, often ascribing a development to some national hero, while ignoring the process of development as a whole or parallel developments in other countries (e.g. the car, the airplane, the telephone).

On the other hand, Zuse is indeed obscure in Germany overall. Maybe it had to do with the fact that he wasn’t really commercially successful, he did not build some computing Empire out of his inventions. He wasn’t a Silicon Valley style entrepreneur. Something to consider for the engineers among us: it’s not enough to build/invent a thing.

The proof that the Z3 is turing complete is pretty funny:

There is also a sign mentioning Konrad built the first computer on the U-bahn (I think it is U5?)

The Deutsches Technikmuseum commemorates his contributions too. It was one of the things I marveled at in that geek paradise of a museum. Because otherwise the only time I ever heard of Zuse is in a few paragraphs in the cursory and customary "History of Programming Languages" that opened my PL class at uni.

(Claims below are completely opinions, very unsubstantiated, yours might vary, doesn't matter, just my musings. Take it as a light-hearted commentary, not some hill I'd be willing to die on.)

So what even amuses me further is how I find the question of the earliest computer as largely political for lack of a better term. Most of the world would say it's either Alan Turing and his work at Enigma, some would claim Charles Babbage. Growing up in SE Asia, some of my elementary books would even claim the abacus as the earliest "computing device" (I disagree on principle). And of course, Berlin, Germany would say it is Konrad Zuse.

It seems to me this is because there is a very loose definition of "achieving computing". I won't get into Turing vs Zuse, but consider the arguments I remember for the abacus:

- it aids computation, was used as, basically, a calculator

- yes you can still make mistakes, but hey garbage-in garbage out!

- interpreting the configurations of the device to mean something is not so different from interpreting a computer's state through the configuration of lights on your monitor

Of course, if you qualify the debate as achieving electronic computing, then we have a bit more to chew on. But I imagine you could hammer arguments to go either way even with the "electronic" qualifier.

I think that's also because Zuse was always relatively obscure during the war, he never was a "nazi celebrity" like Wernher von Braun. Zuse's computer experiments were not considered "vital to the war effort", funding got denied so it always remained a "basement project". And after the war computers were hardly the most important thing to work on in Germany either. Also AFAIK Zuse himself didn't consider his inventions all that important and earth-shattering, at least before and during the war, he "just" needed a tool to help with computations, so he built one.

I clicked through the first link because I wanted to see what was "funny" about it. Turns out, the way you simulate a Turing machine on the Z3 is very similar to the execution model of AWS step functions.

Zuse is one of the more underappreciated figures in the foundational periods of computer science due to this fact.

I find it quite interesting that the fact that he was on the losing side of that war meant that he had to make due with limited resources which positively influenced his design choices and as such shaped his perspectives of what computers can and should be.

Neil Gershenfeld at the MIT Center for Bits and Atoms has often said that 'computer science is one of the worst things to happen to either computing or science. The canon of computer science that's currently taught prematurely froze a model of computation based on 1950s technology'

I think you can see a sort of stunted alternate path of computation and the connection it has to the physical world in the kinds of projects that Zuse participated in post WWII:

For various reasons Turing captures the contemporary pop culture imagination but I have a feeling that historians in 50-100 years will look back at Zuse as being equally if not more so influential.

I bet that Von Neumann would get a chuckle at how influential his throw away architecture ended up being to our society and would agree with Gershenfeld about how unfortunate it is that its success prematurely froze the model of computation.
