Charles Sealsfield was the pseudonym of Carl (or Karl) Anton Postl, who was an American novelist.
Background
Carl Anton Postl was born on March 3, 1793 at Popice u Znojma (Poppitz) near Znojmo in Moravia, then part of the Austria-Hungary Empire (now Czech Republic). He was the eldest child of Anton and Juliane (Rabel) Postl. His father was the justice of the village.
Education
Karl attended the Untergymnasium at Znaim from 1802 to 1807, and in 1808, entered the college of the Kreuzherrenstift in Prague, five years later becoming a novice in the monastery.
Career
After a few years of monastic life he sought freedom in flight. All efforts to find him on the part of the police of Prague and Vienna were ineffectual; the fugitive monk, Karl Postl, had vanished forever.
In the fall of 1823, however, one Charles Sealsfield appeared in New Orleans. He traveled through the Southern states, through the Mexican province of Texas, and probably also in Mexico, observing with the eye of the artist, the historian, and the ethnographer. In 1824 he came to Kittanning on the Alleghany, near Pittsburgh, where he remained until late in 1825.
He returned once more to New Orleans in 1826 and in August sailed thence for Havre. In 1827 the well-known firm of J. G. Cotta of Stuttgart published the two volumes of Die Vereinigten Staaten von Nordamerika, nach ihrem Politischen, Religiisen, und Gesellschaftlichen Verhaltnisse Betrachtet, by Charles Sidons, a pseudonym which Sealsfield never used again. In 1828 this work appeared anonymously in English translation in two parts: The United States as They Are, and The Americans as They Are; Described in a Tour through the Valley of the Mississippi.
Before the second part appeared, Sealsfield had already published his vitriolic denouncement of the Metternich regime in Austria as it is; or Sketches of Continental Courts, By an Eye Witness. The sale of this book was forbidden in Germany and Austria.
In June 1827 Sealsfield returned to America and resided for a time in Philadelphia as correspondent for Cotta's German journals, but he soon returned to his former home at Kittanning, Pennsylvania, where he wrote the first of his novels, Tokeah; or the White Rose, published in 1828 in two volumes. This novel appeared in German as Der Legitime und die Republikaner (3 vols. , 1833).
In 1828 Sealsfield returned once more to the Southwest and to Mexico, and apparently entered upon various business enterprises. He was active as a journalist from 1829 until 1832, but retired in the latter year to Switzerland where he continued to reside save for return visits to the land of his adoption in 1837, 1850, and 1853.
The period of Sealsfield's greatest literary activity falls between the years 1834 and 1843. Sealsfield continued his anonymity until 1845, when, upon the insistence of his publishers, his complete works were published in fifteen volumes, 1845-47, under the name of Charles Sealsfield.
In 1858 he bought a small estate near Solothurn, Switzerland, and spent his remaining years there in great seclusion. He had become a citizen of the United States. Only upon the death of the bachelor recluse of Solothurn, through a provision in his will, was it finally revealed to the world that Charles Sealsfield and the fugitive monk, Karl Postl, were one and the same.
Views
In his works instead of concentrating on a single character, Charles Sealsfield desired to operate with a whole people as his hero.
