Jean-Baptiste Schwilgué

Jean-Baptiste Schwilgué.

Jean-Baptiste Schwilgué (born in Strasbourg in 1776, died in the same place in 1856) was the author of the third astronomical clock of Strasbourg Cathedral, built between 1838 and 1843 (not 1842, as it is written on the clock itself). In 1844 Schwilgué, together with his son Charles, patented a key-driven calculating machine (see the link in the External Links section), which seems to be the third key-driven machine in the world, after that of Luigi Torchi (1834) and James White (1822).^[1]

He produced a number of clocks for church towers, of which the only one still functioning in Strasbourg is that of Saint Aurelia’s Church, Strasbourg.
