What is the name of the real person that Andy dufrene character was based on?

The character Andy Dufresne from Stephen King's novella "Rita Hayworth and Shawshank Redemption" is not directly based on a specific real person. However, King drew inspiration from various sources and experiences, including stories he heard about prison life and wrongful convictions, rather than a singular individual. The narrative reflects broader themes of hope, resilience, and the human spirit rather than a direct biography.
