Forensic Software Pieces Together Leibniz’s Last Puzzle

Behind an unmarked door in Hanover, Germany, a bearded young man with stylish glasses and a pierced lip is loading 350-year-old pieces of paper onto glass plates for digitization by a souped-up scanner. These pieces of paper are part of an immense puzzle. If solved, it could give insights into one of the greatest minds of all time: Gottfried Wilhelm Leibniz. more

Digital Reconstruction of Historical Library Material

The polymath Gottfried Wilhelm Leibniz used a special knowledge system: parts of his manuscripts and working papers, e.g. copies and excerpts, were cut by him and arranged in a so-called “slip box”, which is a large box of notes. In the project presented, an automated virtual assistance system was developed to restore the original connections of the notes at the moment of their formation. The result of the project is an innovative mass procedure for puzzling and scanning historical handwritten documents. More

The great polymath Gottfried Wilhelm Leibniz noted his thoughts and ideas on countless pieces of scrap paper – an immeasurable wealth of knowledge as paperwork in the most literal sense. Using digital reconstruction, the Leibniz Puzzle project is set out to shed some light on his ideas. more

Insights into the City Archives

Many people keep a collection of papers, documents and memories at home. Basically, that can represent an official and private archive that can go back several generations, depending on the family. The Cologne City Archives has a similar structure. It dates back to 922, and thus to the early Middle Ages. More
