As he had numerous different creations to chip away at, however this development dragged his advantage and consideration regarding itself just and he continued working for the improvement of his gadget.

  • “"To know Chester Carlson was to like him, to love him, and to respect him. He was generally known as the inventor of xerography, and although it was an extraordinary achievement in the technological and scientific field, I respected him more as a man of exceptional moral stature and as a humanist. His concern for the future of the human situation was genuine, and his dedication to the principles of the United Nations was profound.
