Is tin noxious?

The first Rin-Tin-Tin was a German shepherd brought back to the United States from France after World War I by a serviceman named Lee Duncan. Duncan trained him as a police and war dog, then...

~sigh~. No, Rin Tin Tin did NOT discover tin. Rin Tin Tin was a dog.

If you mean How did tin get it's name, then the answer comes from the Latin word stannum, a name for the element tin. (Tin's chemical symbol is Sn, coming from the word stannum) Hope it helps. :P

It's cheaper to make cans with a main steel body and coat them with tin. Strength of steel and the corrosion resistance of tin.

Tin Tin's dog is called Snowy.
