After the treaty of Tilsit had been signed by Napoleon and the King of Prussia, Chamisso visited France, where his family regained possession of part of their estates, and our author secured, for a short time, the post of professor at the school at Napoléonville in the Vendée. It was during his stay in France that Chamisso was drawn into the circle of Madame de Stael, and he followed her to Coppet, where she had been exiled by Napoleon in 1811. In the house of this "magnificent and wonderful woman," as he calls her in his letters, he passed incomparable days in the company of August Wilhelm von Schlegel, Madame Récamier and other celebrities. It was also then that he began to study botany on the advice of an English friend. Soon, however, Chamisso returned to Berlin, which was to him what Delphi once was to the ancient Athenians. He continued his botanical studies and at the age of 31 entered the University as a student of medicine. Again the war broke out, and the uprising of the Germans against Napoleon involved Chamisso once more in the popular hatred against the French. Anyone who lays claim to some historical knowledge and a dash of culture is acquainted with the events of 1813. A wave of patriotic enthusiasm swept over Germany, and Germans rose like one man, in answer to the appeal of Frederic William, King of Prussia. Houses, streets and universities resounded with the clash of arms and the shouts of war-like patriots. In the midst of this effervescence Chamisso suffered greatly. He loved Germany and liberty, but he also cherished France, his native land; moreover, he could not help admiring Napoleon, in spite of the latter's tyranny. While the German poets Koerner and Eichendorff took up arms, while Arndt, Rückert and Uhland fired the courage of their compatriots by their warlike songs, Chamisso not only stood alone, but was even exposed to danger. His friends therefore decided to remove him from Berlin. Lichtenstein, his professor at the University, found him a position as teacher in the family of Count Itzenplitz, where he taught French and botany. He was sufficiently near to the capital to be kept acquainted with the gradual development of the all-important crisis, and yet remained free from any unpleasant personal contact with it! Here, at Kunnersdorf, the family seat of Count Itzenplitz, scarcely a day's journey from Berlin, while occupied with the study of botany and other sciences, Chamisso conceived the idea of "The Shadowless Man," and with rapid pen completed the story. One day, to divert himself and to amuse the wife and children of his friend Hitzig, whom Heine calls _Der Dekan der Schlemihle_, he wrote Peter Schlemihl. In 1814, this wonderful narrative was brought to the notice of Baron de la Motte Fouqué, the celebrated author of _Undine_, under whose auspices the book was published with the following letter from de la Motte Fouqué to Julius Edward Hitzig, by way of introduction:--
