If you mean the mammal, tigers were first of all created by evolution or God, not invented. If you mean the Tiger I or Tiger II WWII army tank, then that would be the Germans. The Russians invented the Tigr vehicle.
The Tiger 1 tank has a crew of 5, I know this because of a book called Tanks inside out. (The Tiger 2 or King Tiger also has a crew of 5)
the tiger tank was one of the Germans most heavily armoured tanks
There is only one tank named the Tiger and that's the Panzer 6, the biggest panzer was the Panzer 8 Maus
There was only two tigers, the tiger 1, which was very powerful and armourd but slow. The king tiger, twice the power and armore, but was twice as slow. The Tiger 1 and Tiger 2 had the same top road speed. Go to Wikipedia for more info.
Yes, there is a working Tiger 1 at the Tank Museum at Bovington, England.
The tiger is six and the king tiger is seven Clarification: both the Tiger 1 and Tiger 2 (King Tiger) are designated Panzerkampfwagen VI (or panzer 6) the tiger 2 being designated Panzerkampfwagen VI Ausf.B Tiger II. I'm not sure what a Panzer 7 was.
The Tiger I tank stopped production in August 1944 and stopped usage in combat in May 1945. The Tiger II tank both stopped Production and usage in April 1945.
