The middle of the 19th century witnessed an international race towards scientific and technical standardization. In France, after receiving news of Scheibler's achievement, the government set up a commission to establish a French standard pitch. This group of experts included the scientist Jules Lissajous (1822-1880) who, with the committee's approval, created a standard tuning fork at 335Hz G . In the process he invented an optical method for calibrating tuning forks using so-called Lissajous figures (see photo), which proved to be of great utility in many other fields (such as in the calibration of television transmission in the 20th century).[1]
