I.M. Pei, one of the most heralded of 20th century architects, died on May 16, 2019 at the age of 102. In this "CBS Sunday Morning" report which aired on October 21, 1979, Pei talked with correspondent Marlene Sanders as they toured Boston's newly-dedicated John F. Kennedy Presidential Library (which he designed), and discussed creating a public space that captured the essence, and promise, of the man who was our nation's 35th president.
