Because no scientific work is considered a "discovery" until it has been independently verified by several other scientists in different places. If their work verifies the original claim, then it is indeed, a "discovery" by the first scientist in question. If the work of the other scientists cannot verify it, or vary wildly from the first scientist's work, then it is not a new "discovery".
This scientist was Ernest Rutherford.
He was J.J.Thomson
