History of YSI
- Founded: 1948
- Founders: Hardy Trolander, John Benedict, David Jones
Two engineers, Hardy Trolander and John Benedict, and chemist David Jones founded the Yellow Springs Instrument Company in 1948, investing $100 each in a partnership forged at Antioch College. David Case and automatic radio compass inventor Fred Hooven joined shortly after as the fourth and fifth members.
The young company built whatever instrument work it could find, from dielectric constant meters to telethermometers. Its breakthrough came in 1963 with the first commercial dissolved oxygen meter for field and lab use, which made YSI the reference name in DO measurement.
Decades of expansion followed in environmental monitoring, multiparameter sondes, and continuous water quality systems. The 2011 ITT acquisition, immediately followed by the Xylem spin-off, placed the brand inside a global water technology platform. The Yellow Springs headquarters still operates in the same Ohio village where the company started.
