“Soon will come a time when all God's children can not only feel the sun shining on their faces, but also witness with their own eyes its rising and its setting.”
      on ending blindness 


An inventor, author, public servant, and philanthropist, Sanford Greenberg was blinded at age nineteen while an undergraduate at Columbia.  With the help of his roommate, Art Garfunkel, Greenberg returned to college, went on to earn a PhD at Harvard, serve as a White House Fellow, and launch multiple highly successful enterprises while also serving as chairman of the federal Rural Healthcare Corporation and as a member of the National Science Board.  

The driving force of Sandy Greenberg’s life has been his determination to eradicate blindness from human history. In 2020, Greenberg and his wife, Sue, awarded the first Greenberg Prizes to researchers at the cutting edge of achieving that goal. They have since launched the Sanford and Susan Greenberg Center to End Blindness at Johns Hopkins Medicine’s Wilmer Eye Institute, where Greenberg serves as Board chairman. In 2023, Harvard’s Graduate School of Arts and Sciences honored Greenberg with its Centennial Medal, bestowed on those alumni “who have made fundamental and lasting contributions to knowledge, to their disciplines, to their colleagues, and to society.”

Founded in October 2021 in partnership with Johns Hopkins Medicine’s Wilmer Eye Institute, the Sanford and Susan Greenberg Center to End Blindness is the world’s only facility devoted solely to ending this ancient scourge for everyone and for evermore. The Center’s roots trace back to a Detroit hospital in 1961 when Sandy Greenberg, newly blind, made a tikkun olam — a sacred vow to God in his Jewish faith — that he would do everything in his power to make sure others would not have to suffer his same fate. “It was an insane, adolescent promise,” Greenberg recalls, “but it stayed with me all this time. The launch of this center means the end of blindness is near.”
