Really? I thought, it was one of the Newton's doom which couldn't be achieved.

When did humanity know alchemy is a real science?

The knowledge about the possibility comes from nuclear physics ( not sure about dates here - 1900-1940s? ) - however there is a difference between theoretical possibility and can actually be made to happen in the lab - I think that wasn't experimentally shown until the 1970's or 1980s.
