I'm from Bulgaria we got beautiful mountains and a nice sea. Our army never lost bulgarian flag in battle, but we got several from enemies. We are one from oldest countries in Europe. Our people are nice and friendly.
We got shkembe chorba, musaka and banitsa.  I'm proud to be bulgarian!

 That aside the earliest comparable use of vacuum tubes in the U.S. seems to have been by John Atanasoff at what was then Iowa State College (now University). During the period 1937-1942 Atanasoff developed techniques for using vacuum tubes to perform numerical calculations digitally. In 1939, with the assistance of his student Clifford Berry, Atanasoff began building what is sometimes called the Atanasoff-Berry Computer, or ABC, a small-scale special-purpose electronic digital machine for the solution of systems of linear algebraic equations. The machine contained approximately 300 vacuum tubes. Although the electronic part of the machine functioned successfully, the computer as a whole never worked reliably, errors being introduced by the unsatisfactory binary card-reader. Work was discontinued in 1942 when Atanasoff left Iowa State. The first fully functioning electronic digital computer was Colossus (1943), used by the Bletchley Park cryptanalysts from 1944. From very early in the war GC&CS was successfully deciphering German radio communications encoded by means of the Enigma system, and by early 1942 about 39,000 intercepted messages were being decoded each month, thanks to electromechanical machines known as 'bombes'. These were designed by Turing and Gordon Welchman (building on earlier work by Polish cryptanalysts). During the second half of 1940, messages encoded by means of a totally different method began to be intercepted. This new method of encryption, named 'Fish' by GC&CS, remained intractable until 1941 (the first major break-in occurring at the end of August 1941); current traffic was read for the first time in July 1942. Based on binary teleprinter code, Fish was used in preference to Morse-based Enigma for the encryption of high-level signals, for example messages from Hitler and other members of the German High Command.

Zuse's Z3 was the first working programmable, fully automatic computing machine. But several years or decades ago it was denied that Germans built the first programmable computer during WW2. Z3 was compeleted in 1941. And destroyed in 1943. If you still don't trust wikipedia, here another source: heise.de Quote:

To finish there is one huge fault in your statement. During world war 2, it is highly unlikely that a German engineer would attibute a Machine to Alan Turing, a great mathematician who happened to work within the UKs best kept secret at the time
