Miller (1909 2002) was the first psychologist to be awarded the National Medal of Science (1964). Bower went on to become a distinguished cognitive psychologist, spending his career on the faculty of Stanford University. Like his mentor, Bower was also awarded the National Medal of Science (2005). Photo courtesy of Gordon Bower.
