Karsten Pagel holds a Bachelor of Science degree in Business Informatics from Germany. As an independent researcher, he brings a unique interdisciplinary perspective to problems in historical linguistics and cryptography, combining computational methods with traditional philological expertise. His primary research focuses on the Voynich Manuscript (Yale University, Beinecke MS 408), widely considered one of the most enigmatic documents in the history of cryptography. His systematic analysis proposes that the manuscript is a quadrilingual pharmaceutical compendium combining Latin (~60%), Hebrew (~25%), Arabic (~10%), and Persian (~5%) medical terminology. The methodology employs phonetic vector analysis and morphological segmentation, identifying 432 lexical terms with an average confidence of 91.8%. The research situates the manuscript within the multilingual medical traditions of the 15th-century Mediterranean, particularly the Jewish-Italian Salernitan school, where physicians routinely worked across linguistic boundaries. This interpretation is supported by structural correspondence with known pharmaceutical texts such as Circa instans and statistical validation including Zipf distribution analysis. Beyond historical research, Pagel develops enterprise software solutions, applying his informatics background to practical business applications. Academic Profile Name: Karsten Pagel Degree: B.Sc.
