September 23, 2022. Dr. Sandy Greenberg talks to host Ben Shaberman about his incredible life's journey of going blind suddenly at the age of 19 to earning advanced degrees from Columbia and Harvard, receiving a White House Fellowship, serving on the Council of Foreign Relations, and founding the company which developed the computer system for the lunar excursion module that transported the first men to the moon. His compelling memoir, "Hello Darkness, My Old Friend," reflects on these and many other accomplishments as well as his lifelong friendship with Art Garfunkel. Dr. Greenberg and his wife, Sue, launched the Campaign to End Blindness to generously fund vision-restoring research.
