Edison's deafness helped him as it blocked out noises and prevented Edison from hearing the telegrapher sitting next to him.One of Edison's mentors during those early years was a fellow telegrapher and inventor named Franklin Leonard Pope, who allowed the then broke youth to live and work in the basement of his Elizabeth, New Jersey home.On December 25, 1871, he married Mary Stilwell, and theyhad three children, Marion Estelle Edison, Thomas Alva Edison, Jr., and William Leslie Edison.
