But researchers theorized their existence. And starting in the 1930s scientists at Lawrence Berkeley National Laboratory - or, the Rad Lab, as it was called then - began building the big machines and assembling the teams of scientists and engineers to chase those elements down.
Over the next several decades Berkeley Lab researchers were credited with discovering, Lab researchers were credited with discovering, or creating collaboratively with other labs, #16elements.
