It is said that one day, when taking his usual walk, he came upon two former soldiers who were just preparing to fight a duel and were on their way to the dueling ground. He succeeded in getting them to tell him the cause of their quarrel, and after a time tempted them to come with him into what I fear we should call at the present day a saloon. Here, over a glass of wine, he finally persuaded them to make peace and seal it effectually. It is hard to reconcile this absolute simplicity of character and kindness of heart with what is sometimes assumed to be the typical, distant, abstracted, self-centered ways of the great scientist. Few men have had so many proofs of the lofty appreciation of great contemporaries. Many incidents serve to show how much Napoleon thought of the distinguished scholar who had created a new department of science and attracted the attention of the world to his splendid work at Paris. Not long after he became emperor, Napoleon named him Honorary Canon of the {191} Cathedral of Notre Dame; and when he founded the Legion of Honor, he made the Abbé one of the original members. Shortly after these dignities had been conferred upon him, it happened that the Abbé fell ill; and Napoleon, having sent his own physician to him, went personally to call on him in his humble quarters, saying to the physician: "Remember that you must cure Abbé Haüy, and restore him to us as one of the glories of our reign." After Napoleon's return from Elba, he told the Abbé that the latter's "Treatise on Crystallography" was one of the books that he had specially selected to take with him to Elba, to while away the leisure that he thought he would have for many years. Abbé Haüy's independence of spirit, and his unselfish devotion to his native country, may be best appreciated from the tradition that after the return from Elba, when there was a popular vote for the confirmation of Napoleon's second usurpation, the old scientist voted, No. In spite of his constant labor at his investigations, his uniformly regular life enabled him to maintain his health, and he lived to the ripe age of over seventy-nine. Toward the end of his career, he did not obtain the recognition that his labors deserved. After the Restoration, he was not in favor with the new authorities in France, and he accordingly lost his position as professor at the University. The absolute simplicity of life that he had always maintained now stood him in good stead; and, notwithstanding the {192} smallness of his income, he did not have to make any change in his ordinary routine. Unfortunately, an accidental fall in his room at the beginning of his eightieth year confined him to his bed; and then his health began to fail very seriously. He died on the 3 June, 1822.
