- Leupold, Jacob

[br]b. 25 May 1674 Planitz, Germanyd. 12 January 1727 Leipzig, Germany[br]German scientist famous for his nine-volume work, which comes under the general title Theatrum Machinarum.[br]Leupold was essentially an academic of great learning in the tradition of the Renaissance. He was basically a scientist with a principal interest in the extraction of minerals, and in 1725 was made a Commissioner of Mines. He was also a member of the Academy of Berlin. The nine volumes of his work Theatrum Machinarum are detailed studies of the various disciplines, with existing practices illustrated in woodcuts. These nine volumes (see below, Bibliography) were brought to England by the younger members of the aristocracy returning from their Grand Tour. The large water-wheel created for raising water at Painshill, in Surrey, was a straight copy of the relevant illustration in Wasser- Bau-Kunst (1724). The volume Mühlen-Bau-Kunst is a good reference book on German milling practice, which remains essentially unchanged in existing mills.[br]BibliographyThe nine volumes of Theatrum Machinarum were all reprinted in Hanover in the 1980s. The original dates of publication were as follows: 1722, Schau-Platz der Rechen-und Mess-kunst; 1724, Schau-Platz der Wasser-Bau-Kunst; 1724, Schau-Platz der Wasser-Künste; 1724, Schau-Platz des Grundes der mechanischen Wissenschaften; 1725, Schau-Platz der Heb-Zeuge; 1726, Schau-Platz der Gewicht-Kunst und Waagen; 1726, Schau-Platz der Brücken und des Brücken-Bauer, 1729, Zusatz zum Schau-Platz der Machinen und Instrumenten; 1735, Schau-Platz der Mühlen-Bau-Kunst.KM
