The Board of Trustees, scientists, and staff of the Marine Biological Laboratory (MBL) in Woods Hole, MA, mourn the passing of our valued colleague and friend William T. Golden, who served the laboratory for nearly 40 years as a corporation member, trustee, and honorary trustee. Throughout his career, Bill invested heavily in the advancement of science, influencing the development of U.S. science policy and the public’s understanding of it. A true philanthropist, Bill generously supported the MBL’s research and educational programs, and his commitment and enthusiasm for the MBL’s Science Journalism Program was contagious. If anyone knew the importance of communicating science, it was Bill. For five decades, he used his skill as a communicator to advise our nation’s presidents, to bring science to the government, and to garner public support of the sciences. We are grateful for having had the privilege of working with Bill. He was a wise counselor and visionary who helped to shape our institution for decades and he will be deeply missed. On behalf of the entire MBL community, we extend our heartfelt sympathies to his wife, Catherine, and the entire Golden family.
