Billy Frank, Jr. was a tireless advocate for Indian treaty rights and environmental stewardship, whose activism paved the way for the “Boldt decision,” which reaffirmed tribal co-management of salmon resources in the state of Washington. Frank led effective “fish-ins,” which were modeled after sit-ins of the civil rights movement, during the tribal “fish wars” of the 1960s and 1970s. His magnetic personality and tireless advocacy over more than five decades made him a revered figure both domestically and abroad. Frank was the recipient of many awards, including the Martin Luther King, Jr. Distinguished Service Award for Humanitarian Achievement. Frank left in his wake an Indian Country strengthened by greater sovereignty and a nation fortified by his example of service to one’s community, his humility, and his dedication to the principles of human rights and environmental sustainability.
