Was Zuse's Z3 the First Programmable Computer?
Roland Piquepaille writes "Several years before the Colossus in the U.K. and the ENIAC in the U.S., the Z3, built by Konrad Zuse in 1941, was crunching numbers in Germany. In a short article, the Register reports on allegations that the Z3 was the first programmable computer. Based on a binary floating-point number and switching system, it had all the attributes of today's computers, such as a control block, a memory, and a calculator. But it didn't have the ability to store the program in the memory together with the data because the memory was too small. It had a 64-word memory of 22 bits each and was able to handle four additions per second and to do a multiplication in about five seconds. And it was pretty big: five meters long, two meters high, and 80 centimeters wide. It was destroyed during WWII, and later rebuilt in 1960/1961. You'll find more details, pictures and references in this analysis of this ancestor of modern computing. [Additional note: you can find other references to the Z3, Colossus and Eniac computers in this former Slashdot item, posted in October 2000.]"
Babbage's Analytical Engine (which first computer programmer was Ada Byron, daughter of Lord Byron).
I DO happen to think that Zuse should get credit for the first computer. I remember hearing all that historical stuff about who made the first computer. But then I read what Zuse had accomplished and when he did it. His concepts were way ahead of everyone else. He basically invented the programmable computer. No, its not just like the architecture of our computers today, but he certainly laid the foundation - or would have had his research been shared.
The crazy thing is that he developed all his ideas and machines isolated from the rest of the western world due to the Nazis. That to me is even more incredible. Give him a trophy.

I've always wondered what the Nazis would have accomplished if Hitler and his henchmen had been slightly more practical minded and had:
(1) Let the generals run the combat. AFAIK there were several opportunities to either retreat and regroup or to give up ground to assist other units that could have actually won the Eastern Front.
(2) Made the Final Solution a post-war ambition. There were a lot of resources wasted on the Death Camps and other essentially political/sociological obsessions. Not only did this limit Nazi Germany's resources, but it limited their access to a large segment of educated people.
There's probably a mildly entertaining alt-history story about a Nazi government that decides to pursue its racial ambitions after it conquers Russia and England and so succeeds due to the reallocation of resources.

And he wrote a chess program in this language, before he actually had a machine to run it on.
