Mr. Lossing, speaking of his friend and fellow engraver, says: "Dr. Anderson worked industriously with an every-cheerful spirit; was kind and loving, and generous to all around"in a word, he lived a pure, simple, blameless, and useful life. He was of less than medium height, compactly built, with mild and beautiful dark gray eyes and a face ever beaming with indices of kindly feelings and serenity of spirit; and for many years that venerable head was surrounded, as by a halo, with white locks and beard. His voice was soft and low. He was genial in thought and conversation, and had a quick perception of genuine humor. To him the world was a delightful place to live in, because it was a reflex of his own sweet spirit. He was extremely regular in all his habits. He once said to a friend: ‘I would not sit up after ten o’clock at night to see an angel.’"
