Achille Brocot
1817-1874
Achille Brocot was a French clockmaker and amateur mathematician. He is known for his discovery of the Stern–Brocot tree, a mathematical structure useful in approximating real numbers by rational numbers, this sort of approximation is an important part of the design of gear ratios for clocks. Several improvements in clock design were attributed to Brocot. He invented the "Brocot Suspension", which enabled time keeping to be regulated by altering the length of the pendulum suspension spring by a key turned in the dial.

Very Rare 19th Century Coromandel Veneered Year-Running Clock by Thomas Cole
By Achille Brocot, Thomas Cole (Clockmaker)
Located in London, GB
A Superb Coromandel-Veneered Mantle Clock
The case constructed of very well-figured Coromandel giving the maximum amount of decorative effect, with gilt bronze accents; the plinth base of rectangular form, with everted stepped corners, and precisely chased gilt bronze figures, two representing Mercury-the god of travel and merchants with his winged helmet and coin purse in hand; the others representing Fortuna-the goddess of luck; the sides glazed, with mooresque arcaded pierced mounts enclosing a vase, in gilt bronze with overlapping palm trees above: the top of domed form with an octagonal platform, surmounted by an architectural dome, its engraved detail and structure reminiscent of Byzantine prototypes. The silvered chapter ring with Roman numerals for the hours, and within an arabesque dial divided into quadrants, with the key aperture at 6 o'clock. Below, the manual calendar, and a semi-circular thermometer. The dial signed by the retailer "Hunt & Roskell / London." The mechanism replaced with a one-year duration movement by Achille Brocot.
