Keithley Instruments (→ WikiData) was founded by Joseph F. Keithley (1915-1999) in Cleveland, OH, in 1946.
In 1965, they moved to Solon, OH.
In 2010, Keithley became an indirect wholly owned subsidiary of Danaher Corporation, merged with Tektronix, and shifted manufacturing to Tektronix facilities.
