This partnership was entered into about the year 1436. Upon the completion of the agreement the implements and materials for the new art were removed from St. Arbogaste to the house of Andrew Dritzehen, with whom, as perhaps the ablest mechanic in the association, Gutenberg thenceforth carried on his experiments. These seem to have nearly approached completion, when Dritzehen was unfortunately seized with an illness which ended fatally. His death took place in 1438, before the expiration of the term allotted for the partnership, and while he was still indebted to Gutenberg in the sum of eighty-five florins. Gutenberg, as soon as he heard of his death, sent his servant Laurence Beildeck, to Nicholas Dritzehen, the brother of the deceased, and requested that no one might be admitted into the workshop, lest the secret should be discovered, or the materials be stolen. But they had already disappeared; and this fraud, as well as the claims of George and Nicholas Dritzehen to succeed to their brother’s share, produced a lawsuit with the surviving partners. In the prosecution of this lawsuit, out of a large number of witnesses summoned, the depositions of sixteen were taken; and in the following extracts from the evidence of the most material, we may gather what the secret was which Gutenberg was so desirous to preserve. “John Schultheissen deposed, that Laurence Beildeck came to his house, to see Nicholas Dritzehen, when Andrew Dritzehen was lying dead, and that the said Laurence Beildeck thus spoke to the said Nicholas Dritzehen:--‘Your brother, Andrew Dritzehen, now happy, had four “stücke” lying underneath in a press. Therefore John Gutenberg desires that you will take them therefrom, and thoroughly separate them one from the other, and lay them on the press, so that it may not be seen what it is.’ Then Nicholas Dritzehen went and looked for the ‘stücke,’ but found nothing.” “Item, Hannsz Schultheisz hatt geseit das Lorentz Beildeck zu einer zit heim inn sin husz kommen sy zü Claus Dritzehen als diser gezuge jn heim gefürt hette, Als Andres Dritzehen sin bruder selige von todes wegen abgangen was, und sprach da Lorentz Beildeck zu Claus Dritzehen, Andres Dritzehen uwer bruder selige hat iiij stücke undenan inn einer pressen ligen, da hatt uch Hanns Gutemberg gebetten das ir die darusz nement und uff die presse legent von einander so kan man nit gesehen was das ist, Also gieng Claus Dritzehen und suchete die stücke do vant er nutzit.” “Conrad Sahspach deposed, that Andrew Heilman came to him in Kremer street and said, ‘My dear Conrad, as Andrew Dritzehen is departed, and as you made the presses, and know about the matter, do you go thither and take the “stücke” from the presses, and disjoin them from one another, so that no man may know what it is.’ But when this witness wanted to do so, and looked for them on the morrow of St. Stephen’s day, the whole was gone.”
