<P> The first discovered synthetic element was curium , synthesized in 1944 by Glenn T. Seaborg , Ralph A. James , and Albert Ghiorso by bombarding plutonium with alpha particles . The discoveries of americium , berkelium , and californium followed soon . Einsteinium and fermium were discovered by a team of scientists led by Albert Ghiorso in 1952 while studying the radioactive debris from the detonation of the first hydrogen bomb . The isotopes discovered were einsteinium - 253 , with a half - life of 20.5 days , and fermium - 255 , with a half - life of about 20 hours . </P>
