It wasn't invented. It's a natural process that was discovered in heavier elements.
The first time a fission chain reaction was produced was in 1942

Leo Szilard invented the fission bomb. Edward Teller invented the fusion bomb. Both were from Hungary.
Yes.

The equation E=mc2 he invented nuclear fission and many other things
it is what happents after a nuclear explosion usually involving radiation poisoning to the surounding area
It's a semi-permeable membrane, so it controls what goes in and out of the cell.
None. The fission bomb was invented in 1933 by the physicist Leo Szilard. The staged fusion bomb was invented in 1949 by the mathematician Stan Ulam and the physicist Edward Teller.

Fission is not an invention. Fission is a natural process, and its functioning is not subject to change. The only materials ordinarily found in nature that undergo fission are various isotopes of uranium. The neutrons released from this process occasionally produce isotopes we usually regard as synthetic, but in such small amounts that for practical purposes they do not exist on earth. Some did, however, exist in the distant past, and probably still do in other parts of space. Nevertheless, in connection with this question, it can be pointed out that people have studied a number of substances that can undergo fission that are only produced synthetically. While the functioning of fission is changeless, the understanding of fission changed substantially in the course of these investigations.
