The University of Washington says the first Nobel laureate in its history, Hans Georg Dehmelt, has passed away in Seattle at the age of 94 after a long illness.
Dehmelt won a share of the Nobel physics prize in 1989 for his work with ion traps, a type of apparatus that uses an array of electromagnetic fields to isolate electrically charged atoms and subatomic particles, and hold them in place for highly accurate measurements.
