Gentex Corporation

A maker of automatic-dimming rearview mirrors for global automakers, Gentex fills most of the world's new cars with mirrors that darken automatically against headlight glare. Founder Fred Bauer launched the company in 1974 in Zeeland, Michigan, building smoke detectors before inventing the first auto-dimming mirror in 1982. Today it also makes dimmable aircraft windows, Klipsch and Onkyo premium audio, and iris-recognition biometric systems.
