Weston Miller Fulton (August 3, 1871 – May 16, 1946) was an American meteorologist, inventor, and entrepreneur, best known for his invention, the "sylphon," a seamless metal bellows used in thermostats, switches, and other temperature-control devices.
Fulton also invented an automatic river gauge while working for the U.S.
Weather Bureau, and played a primary role in the development of the depth charge during World War I.
His company, now called Fulton Bellows after numerous ownership changes, still operates in Knoxville, as part of the United Flexible Group, which acquired it in 2016.
