  8. History of nuclear fusion - Wikipedia

    en.wikipedia.org/wiki/History_of_nuclear_fusion

    The first successful man-made fusion device was the boosted fission weapon tested in 1951 in the Greenhouse Item test. The first true fusion weapon was 1952's Ivy Mike, and the first practical example was 1954's Castle Bravo. In these devices, the energy released by a fission explosion compresses and heats the fuel, starting a fusion reaction.
