Perfectly accurate, Zuse worked in Berlin during the thirties and developed several machines.

Zuse worked on his computers in Berlin in the late 30's and into the 40's. He fled near the end of the war with the Z-4, the only surviving computer...the others were destroyed in Allied bombing raids. Even the Z-4 was *not* in working condition at that time... Read the book...you'll like it!!!

There is also a book (below) you may find interesting. It has the 1962 paper by K. Zuse The Outline of Computer Development from mechanics to Electronics.
