Leroy et fils
The firm of Leroy et fils was founded by Bazile Charles Leroy in 1789. He was a clockmaker to the Emperor Napoleon, The Duke of Orleans, The Duke of Bourbon and Princess Pauline. In 1823, he filed a patent for self-winding atmospheric clock operated by a weather vane and in 1840 a patent for wind clocks. When Charles Louis died in 1865 his son Louis Leroy took over the running of the business.
