Seaborgium was obtained for the first time, simultaneously, by Albert Ghiorso, J.M. Nitschke, J.R. Alonso, C.T. Alonso, M. Nurmia, E. Kenneth Hulet, R.W. Lougheed, Glenn T. Seaborg from Berkeley, USA and by a team from Dubna, Russia - in 1974.
The nuclear reaction used was: 249Cf + 18O---------263Sg

It was Albert Ghiorso who discovered or co-discovered the most elements, 12.As a member of both the Manhattan Project, and later a researcher at UC Berkeley, Ghiorso and his teams uncovered elements 95 (americium) through 106 (seaborgium). All of them are radioactive; and all of them are man-made, having long since decayed in nature.Of them, americium has seen the greatest commercial use, being found in most modern smoke detectors.
Glenn Seaborg was an important radiochemist born in USA.Glenn Seaborg was a member of the teams who obtained for the first time americium, berkelium, californium, curium, einsteinium, fermium, mendelevium, nobelium, plutonium, seaborgium.
When did he discovered? Do you mean what? He discovered Yellow Fever was transmitted by mosquitoes. And if you mean when did he discover it, then the answer you are looking for is he led a research team that discovered this in 1900.
J.J.Thomson has discovered the electron in 1897
