John Gottlob Immanuel Breitkopf, a celebrated printer, letter-founder, and bookseller of Leipsic, died on this day, in the year 1794: he was born there November 23, 1719. After the perusal of a work by Albert Durer, in which the shape of the letters is deduced from mathematical principles, he endeavoured to fashion them according to the most beautiful models in matrices cut for the purpose. His printing-office and letter-foundery acquired very high reputation. It contained punches and matrices for 400 alphabets, and he employed the types of Baskerville and Didot. Finding that engraving on wood had given birth to printing, and that the latter had contributed to the improvement of engraving, he transferred some particulars, in the province of the engraver, to that of the printer; and represented, by typography, all the marks and lines which occur in the modern music, with all the accuracy of engraving, and even printed maps and mathematical figures with movable types; though the latter he considered as a matter of mere curiosity: such was also another attempt, that of copying portraits by movable types. He likewise printed, with movable types, the Chinese characters, which are, in general, cut in pieces of wood, so that a whole house is often necessary to contain the blocks employed for a single book. He improved type-metal, by giving it that degree of hardness, which has been a desideratum in founderies of this kind; and discovered a new method of facilitating the process of melting and casting. From his foundery he sent types to Russia, Sweden, Poland, and even America. He also improved the printing-press. Besides this, his inquiries into the origin and progress of the art of printing, furnished the materials of a history, which he left behind in manuscript. He published in 1784, the first part of “An Attempt to illustrate the origin of playing-cards, the introduction of paper made from linen, and the invention of engraving on wood in Europe;” the latter part was finished, but not published, before his death. His last publication was a small “Treatise on Bibliography,” &c. published in 1793, with his reasons for retaining the present German characters. With the interruption of only five or six hours in the twenty-four, which he allowed for sleep, his whole life was devoted to study and useful employment. FLORAL DIRECTORY.
