French clockmaker
Jean-Baptiste Schwilgué (1776–1856) was the author of the third astronomical clock of Strasbourg Cathedral, built between 1838 and 1843 . In 1844 Schwilgué, together with his son Charles, patented a key-driven calculating machine, which seems to be the third key-driven machine in the world, after that of Luigi Torchi (1834) and James White (1822).
