Bio-Rad Laboratories, Inc. (NYSE: BIO and BIO.B), a global leader in life science research and clinical diagnostics products, today announced that Alice N. Schwartz, Bio-Rad’s co-founder and Director Emeritus, passed away on September 25, 2025, at the age of 99.

Mrs. Schwartz co-founded Bio-Rad in 1952 in Berkeley, California, together with her husband David Schwartz, shortly after graduating with a biochemistry degree from the University of California, Berkeley.

This innovation marked Bio-Rad’s entry into the field of clinical diagnostics, and set the stage for the company's future growth and success.

Mrs. Schwartz played a key role in Bio-Rad’s achievements and remained an active Board member until 2022. Her leadership and passion for scientific discovery created a legacy that continues to inspire the company and the broader scientific community.
