Brocot was a watchmaker, and used the sequence to find best approximations for gear ratios.
-This sequence is used by clockmakers in choosing suitable gear sizes for the clockwork, and features heavily in the book "A Treatise On The Teeth of Wheels, Demonstrating The Best Form Which Can Be Given To Them For The Purposes Of Machinery; Such As Clockwork And Millwork, And The Art Of Finding Their Numbers." written by Charles-Étienne-Louis Camus, and translated from French to English by John Isaac Hawkins in 1873.
+The book "A Treatise On The Teeth of Wheels, Demonstrating The Best Form Which Can Be Given To Them For The Purposes Of Machinery; Such As Clockwork And Millwork, And The Art Of Finding Their Numbers" postdates the sequence, being written by Charles Étienne Louis Camus, and translated from French to English by John Isaac Hawkins in 1873, but shows a method relying in part on guesswork to achieve the same end.
