when he heard that he'd won the Nobel Prize in physics in 1989.
But the German-born American citizen was not surprised: "I'd
been expecting it, because there were rumors that I was being
considered."  Dehmelt was honored for trapping a single electron
as well as for isolating a single atom and watching it make
quantum leaps. Due to Dehmelt's discovery, physicists had to

10,000.  Accepting the prize was "wonderful," he says. "The
physicists walked first into the Great Hall in Stockholm's Town
Hall, as decreed by Nobel himself, and as befits the position of
