Wiki says 1962 (for discovery of its "memory" ability), which helps with believing that Roswell brought something unique along.

This suggests pretty strongly that the concept of "memory metal" was already floating around in the collective consciousness by the time the Roswell crash took place. This would seem to cast a certain amount of doubt on the assertion that a particular memory metal was "unknown to science" before the Roswell crash, at least without a lot more information to back up the claim. Nitinol may have been the first practical memory metal, but it seems clear it was not the first; as Wiki also says: > There are hundreds of alloys that exhibit the shape memory effect > (known as shape memory alloys; SMAs), but only two alloy systems, TiNi > and CuZnAl, have found many practical applications.
