Leo Marcus was a dentist in upstate New York. Eleven years before retiring he started sculpting on anything he could get his hands  on: marble, granite, wood, and metal. At the same time, he found out he was slowly going blind. Most of his sculptures were done by the time he was either partially or completely blind. 

He was never formally trained, but after retirement, he moved to Maine and took some art classes at UMA. Upon his death in 2006, his children discovered over 1,000 works of art. He never sold his art but rather gave pieces away. Now they are in the possession of several Private and public collectors.
