The following particulars concerning the partnership of Gutemberg with Andrew Drytzehn and others are derived from the recital of the case contained in the decision of the judges. Some years before his death, Andrew Drytzehn expressed a desire to learn one of Gutemberg’s arts, for he appears to have been fond of trying new experiments, and the latter acceding to his request taught him a method of polishing stones, by which he gained considerable profit. Some time afterwards, Gutemberg, in company with a person named John Riff, began to exercise a certain art whose productions were in demand at the fair of Aix-la-Chapelle. Andrew Drytzehn, hearing of this, begged that the new art might be explained to him, promising at the same time to give whatever premium should be required. Anthony Heilman also made a similar request for his brother Andrew Heilman.[III-16] To both these applications Gutemberg assented, agreeing to teach them the art; it being stipulated that the two new partners were to receive a fourth part of the profits between them; that Riff was to have another fourth; and that the remaining half should be received by the inventor. It was also agreed that Gutemberg should receive from each of the new partners the sum of eighty florins of gold payable by a certain day, as a premium for communicating to them his art. The great fair of Aix-la-Chapelle being deferred to another year, Gutemberg’s two new partners requested that he would communicate to them without reserve all his wonderful and rare inventions; to which he assented on condition that to the former sum of one hundred and sixty florins they should jointly advance two hundred and fifty more, of which one hundred were to be paid immediately, and the then remaining seventy-five florins due by each were to be paid at three instalments. Of the hundred florins stipulated to be paid in ready money, Andrew Heilman paid fifty, according to his engagement, while Andrew Drytzehn only paid forty, leaving ten due. The term of the partnership for carrying on the “wonderful art” was fixed at five years; and it was also agreed that if any of the partners should die within that period, his interest in the utensils and stock should become vested in the surviving partners, who at the completion of the term were to pay to the heirs of the deceased the sum of one hundred florins. Andrew Drytzehn having died within the period, and when there remained a sum of eighty-five florins unpaid by him, Gutemberg met the claim of his brothers by referring to the articles of partnership, and insisted that from the sum of one hundred florins which the surviving partners were bound to pay, the eighty-five remaining unpaid by the deceased should be deducted. The balance of fifteen florins thus remaining due from the partnership he expressed his willingness to pay, although according to the terms of the agreement it was not payable until the five years were expired, and
