He was professor of physics, from 1955 to 1991, and subsequently,
Professor Emeritus at the
University of California, Berkeley. Hahn was elected a Fellow of the
American Academy of Arts and Sciences in 1971. In 1993 he was awarded the
Comstock Prize in Physics from the
National Academy of Sciences. In 2013, Sir
Peter Mansfield said in his autobiography that Hahn was "the person who really missed out" the
Nobel Prize for his contribution to the principles of spin echoes. He also received the 2016 Gold Medal from the International Society for Magnetic Resonance in Medicine (ISMRM). The award, ISMRM's highest honor, was given to Hahn for his creation of pulsed magnetic resonance and processes of signal refocusing which are essential to modern day MRI. == Death ==
