In due course of time he acquired great fame by his pictures, and was made chief painter to King George III.
and president of the Royal Academy of Arts.

When the Quakers of Pennsylvania heard of his success, they felt that the prophecy of the old preacher as to little Ben's future eminence was now accomplished.
It is true, they shook their heads at his pictures of battle and bloodshed, such as the Death of Wolfe, thinking that these terrible scene, should not be held up to the admiration of the world.
But they approved of the great paintings in which he represented the miracles and sufferings of the Redeemer of mankind.

King George employed him to adorn a large and beautiful chapel at Windsor Castle with pictures of these sacred subjects.

He likewise painted a magnificent picture of Christ Healing the Sick, which he gave to the hospital at Philadelphia.

It was exhibited to the public, and produced so much profit that the hospital was enlarged so as to accommodate thirty more patients.
