Company History

Brookhaven Instruments was founded in 1981 by Dr. Bruce Weiner, a physical chemist, and Dr. Walther Tscharnuter, a physicist. The two met in 1970 as postdoctoral associates working under Prof. Ben Chu at Stony Brook University, who was leading one of the only laboratories in the world at that time investigating Dynamic Light Scattering (DLS).
