Heavily involved in SPIE conferences as a chair, committee member, and presenter since the early 90s, Grundfest was active in the earliest iterations of SPIE BiOS and, along with SPIE Fellow Abraham Katzir, was that symposium’s founding chair. Grundfest was appointed an SPIE Fellow in 1996. “The death of Warren Grundfest is a great loss to the biomedical optics community,” said Katzir, a professor of physics at Tel Aviv University. “Warren assisted me in establishing the SPIE conferences on optics in biology and medicine more than 30 years ago. Using his wide network of researcher and physicians, he paved the road to vibrant conferences. The current success of the SPIE BiOS meetings is largely due to his vision.”
