After Otto Heller published the results of his investigations into the question of Charles Sealsfield's claimed editorship of the Courrier des Etats-Unis in the Euphorion in 1907 (xiv, 718-724), he was convinced that he had disproved “the biographical fable that makes Sealsfield editor of the Courrier des États-Unis.” This assertion was repeated in 1939 in the important Heller-Leon Sealsfield Bibliography and more recently in an article published by the Zeitschrift für deutsche Philologie, to which Professor Eduard Castle of the University of Vienna then made an enlightening but inconclusive reply because he did not have access to copies of the Courrier. In view of the fact that to date Otto Heller's study remains the only one based on an actual examination of the Courrier itself, the weight of evidence must remain in favor of his published conclusions unless these are disproved by more valid evidence from the same source. On the basis of a more complete study of the record it is believed that the following pages will bring such evidence and thus reestablish and confirm Sealsfield's original claim made in his biographical letter to Brockhaus asserting that from 1829-30 he was editor of the Courrier and that he resigned several weeks after news of the French Revolution of 1830 reached America. This will not only correct an unfortunate error in Sealsfield scholarship, but also clear Sealsfield against a charge of untruthfulness.
