Johann Ignaz Fuchs (1821-1893) Johann Ignaz Fuchs was a German engineer and clockmaker. After his apprenticeship as an engineer Fuchs travelled as a journeyman in Germany and Europe. After returning he married the daugther of a late clockmaker in Zerbst; in 1845 he moved the business to Bernburg and called it a turret clock manufactory and precision mechanics workshop. Fuchs built a number of turret clocks at the Prince-Bishopric of Paderborn; he donated one of his turret clocks, which he had exhibited at the World Exhibition in Vienna in 1873, to his birthplace, the city of Welda. It was installed in the church tower of St. Kilian’s. He is also famous for his geographical and astronomical world clock in the town hall of Bernburg (Saale). Fuchs built other instruments as well such as an automatic weighing machine for turnips and an electrical security and alarm system for penal institutions. In 1875 he constructed - without know what the device was intended for - the mechanism for the time bomb that was supposed to sink the emigrant ship Mosel.
