From a letter written by Gutemberg in 1424 to his sister Bertha it appears that he was then residing at Strasburg; and it is also certain that in 1430 he was not living at Mentz; for in an act of accommodation between the nobility and burghers of that city, passed in that year with the authority of the archbishop Conrad III., Gutemberg is mentioned among the nobles “_die ytzund nit inlendig sint_”--“who are not at present in the country.” In 1434 there is positive evidence of his residing at Strasburg; for in that year he caused the town-clerk of Mentz to be arrested for a sum of three hundred florins due to him from the latter city, and he agreed to his release at the instance of the magistrates of Strasburg within whose jurisdiction the arrest took place.[III-14] In 1436 he entered into partnership with Andrew Drytzehn and others; and there is every reason to believe that at this period he was engaged in making experiments on the practicability of printing with moveable types, and that the chief object of his engaging with those persons was to obtain funds to enable him to perfect his invention. [Footnote III-14: The release is given in Schœpflin’s Vindiciæ Typographicæ, Documentum I.] From 1436 to 1444 the name of Gutemberg appears among the “_Constaflers_” or civic nobility of Strasburg. In 1437 he was summoned before the ecclesiastical judge of that city at the suit of Anne of Iron-Door,[III-15] for breach of promise of marriage. It would seem that he afterwards fulfilled his promise, for in a tax-book of the city of Strasburg, Anne Gutemberg is mentioned, after Gutemberg had returned to Mentz, as paying the toll levied on wine. [Footnote III-15: “_Ennelin zu der Iserin Thure._” She was then living at Strasburg, and was of an honourable family, originally of Alsace.--Schœpflin. Vind. Typ. p. 17.] Andrew Drytzehn, one of Gutemberg’s partners, having died in 1438, his brothers George and Nicholas instituted a process against Gutemberg to compel him either to refund the money advanced by their brother, or to admit them to take his place in the partnership. From the depositions of the witnesses in this cause, which, together with the decision of the judges, are given at length by Schœpflin, there can be little doubt that one of the inventions which Gutemberg agreed to communicate to his partners was an improvement in the art of printing, such as it was at that period.
