Johannes Trithemius (1 February 1462 – 13 December 1516), born Johann Heidenberg, was a German abbot, lexicographer, historian, cryptographer, polymath, and occultist who had an influence on later occultism. The name by which he is more commonly known is derived from his native town of Trittenheim on the Moselle River in Germany.
When Johannes was still an infant his father Johann von Heidenburg died. His stepfather, whom his mother Elisabeth married seven years later, was hostile to education and thus Johannes could only learn in secrecy and with many difficulties. He learned Greek, Latin, and Hebrew. When he was 17 years old he escaped from his home and wandered around looking for good teachers, travelling to Trier, Cologne, the Netherlands, Heidelberg.
He studied at the University of Heidelberg. Travelling from university to his home town in 1482, he was surprised by a snowstorm and took refuge in the Benedictine abbey of Sponheim near Bad Kreuznach. He decided to stay and was elected abbot in 1483, at the age of twenty-one. He set out to transform the abbey from a neglected and undisciplined place into a centre of learning. In his time, the abbey library increased from around fifty items to more than two thousand. He often served as featured speaker and chapter secretary at the Bursfelde Congregation's annual chapter from 1492 to 1503, the annual meeting of reform-minded abbots. Trithemius also supervised the visitations of the congregation's abbeys.
Trithemius wrote extensively as a historian, starting with a chronic of Sponheim and culminating in a two-volume work on the history of Hirsau Abbey. His work was distinguished by mastery of the Latin language and eloquent phrasing, yet it was soon discovered that he inserted several fictional passages into his works. His work as a historian has been tainted ever since, the invented passages proved by several scholars.
However, his efforts did not meet with praise, and his reputation as a magician did not further his acceptance. Increasing differences with the convent led to his resignation in 1506, when he decided to take up the offer of the Bishop of Würzburg, Lorenz von Bibra (bishop from 1495 to 1519), to become the abbot of St. James's Abbey, the Schottenkloster in Würzburg. He remained there until the end of his life. Trithemius was buried in this abbey's church, a tombstone by the famous Tilman Riemenschneider was erected in his honor. In 1825 the tombstone was moved to the Neumünster church, next to the cathedral. It was damaged in the firebombing of 1945 and subsequently restored by the workshop of Theodor Spiegel.
Trithemius' most famous work, Steganographia (written c. 1499; published Frankfurt, 1606), was placed on the Index Librorum Prohibitorum in 1609 and removed in 1900. This book is in three volumes, and appears to be about magic—specifically, about using spirits to communicate over long distances. Since the publication of the decryption key to the first two volumes in 1606, they have been known to be actually concerned with cryptography and steganography. Until recently, the third volume was widely still believed to be solely about magic, but the "magical" formulae have now been shown to be covertexts for yet more cryptography content. However, mentions of the magical work within the third book by such figures as Agrippa and John Dee still lend credence to the idea of a mystic-magical foundation concerning the third volume. Additionally, while Trithemius's steganographic methods can be established to be free of the need for angelic–astrological mediation, still left intact is an underlying theological motive for their contrivance. The preface to the Polygraphia equally establishes, the everyday practicability of cryptography was conceived by Trithemius as a "secular consequent of the ability of a soul specially empowered by God to reach, by magical means, from earth to Heaven".
The work has lent its name to the modern field of steganography.
Other works 
Other works include De Laude Scriptorum (In Praise of Scribes) (written 1492, printed 1494), De septum secundeis (The Seven Secondary Intelligences, 1508), a history of the world based on astrology; Annales Hirsaugiensis (1514); and Polygraphiae (1518), credited with being the first published work on cryptology.
- Annales Hirsaugiensis. The full title is Annales hirsaugiensis...complectens historiam Franciae et Germaniae, gesta imperatorum, regum, principum, episcoporum, abbatum, et illustrium virorum, Latin for "The Annals of Hirsau...including the history of France and Germany, the exploits of the emperors, kings, princes, bishops, abbots, and illustrious men". Hirsau was a monastery near Württemberg, whose abbot commissioned the work in 1495, but it took Trithemius until 1514 to finish the two-volume, 1,400-page work. It was first printed in 1690. Some consider this work to be one of the first humanist history books.
