William Daniel Phillips (born November 5, 1948 in Wilkes-Barre, Pennsylvania) is a Nobel Prize winning, American physicist. He shared the Nobel Prize in Physics, in 1997, with Steven Chu and Claude Cohen-Tannoudji. Phillips was born to William Cornelius Phillips and Mary Catherine Savino. He is of Italian and Welsh descent. His parents moved to Camp Hill (near Harrisburg, Pennsylvania) in 1959, where he attended high school and graduated valedictorian of his class. He graduated from Juniata College in 1970 summa cum laude. After that he received his physics doctorate from the Massachusetts Institute of Technology. In 1996, he received the Albert A. Michelson Medal from The Franklin Institute. Phillips' doctoral thesis concerned magnetic moment of the proton in H2O. This led to connections that would be important later in his research. He later did some work with Bose-Einstein condensate.
