Selma Bonham, a pioneering geologist, devoted community leader, athlete, and passionate advocate for education, the arts, and civic engagement, passed away peacefully at the age of 100, after 1 week on hospice. Her century-long life was marked by intellectual curiosity, resilience, and an unwavering commitment to improving the world around her.

Born in Hartford, Connecticut, Selma was raised with the encouragement to challenge expectations and pursue her ambitions without limitation. From an early age, she embraced both physical activity and the arts, studying dance and eventually earning a place with the esteemed Ethel Butler Modern Dance Company. This early dedication to movement and expression would remain a cornerstone of her life. Selma’s academic achievements were groundbreaking for her time. She earned her Bachelor of Science in Geology and Mineralogy from Penn State University, entering a field then dominated by men. Undeterred by barriers, she went on to receive her Master of Science in Geology from Stanford University, where she was the only woman in her program. Her perseverance helped pave the way for future generations of women in the sciences.

She built a distinguished 20-year career with the U.S. Geological Survey in Washington, D.C., contributing to critical mapping projects and undertaking classified work during the Korean War and throughout the Cold War. Her professional accomplishments reflected both her technical expertise and her dedication to public service. Beyond her career, Selma remained deeply engaged in lifelong learning and community involvement. After retiring, she served on the Board of the Gray Panthers, advocating for healthcare reform and social justice. She met with national leaders and remained an active voice in civic discourse, organizing public forums and participating in peace vigils and policy discussions.

Selma’s love of literature, creativity and the arts found expression in her leadership within the Friends of the Mill Creek Library, where she founded and nurtured multiple book clubs that brought together diverse members of the community. She also championed artistic projects, discussion groups, and educational programming at the Mill Creek Senior Center, fostering intellectual engagement across generations. When asked at age 100 what she would recommend for someone to find joy and satisfaction in life she said, “create something.” Selma’s dedication to her community extended to environmental and civic advocacy. She played a key role in a grassroots effort that successfully prevented inappropriate commercial development in Mill Creek, demonstrating her belief that dedicated citizens can make a meaningful difference.

She was also recognized for her spirit and vitality in later life, including winning Macy’s “Better with Age” essay contest at age 83 and appearing as a model in their fashion show—an experience she embraced with characteristic enthusiasm and joy. As an athlete, Selma embodied the principles of healthy living. She was a self-motivated runner starting at age 50 and ran her first 10K to benefit the National Symphony Orchestra at age 60 getting first place in a new age category for women at the time. She went on to win first place ten times in her age group, passing some a decade younger including some men in the Run of the Mill 5K in Mill Creek, WA. She ran until age 86 when she switched to other types of exercise including water aerobics, stationary bike, weights, yoga and walking with her devoted friend/dog, Checkers. She credited her longevity to enjoying consistent exercise and continued regularly even at age 100. She loved the beach and lifelong fitness was the foundation that helped fulfill her wish to celebrate her 100th birthday there with family. Selma relished the importance of getting outdoors and moving. The hummingbird was her spirit animal. Her vitality, enthusiasm and determination inspired all who knew her.

Above all, Selma cherished her family. She shared nearly 50 years of marriage with her husband, Dr. Lawrence Bonham, also a geologist and together they raised three children: Janet, Doug and Lynn. She took great pride in her children and grandchildren, Zoe and Sierra, remaining an active and loving presence in their lives. Selma Bonham will be remembered for her intellect, creativity, joy, humor, kindness, sense of purpose and compassion. Her legacy lives on in the many communities she strengthened, the barriers she broke, and the lives she inspired through her example.

The family will celebrate her life rather than a public memorial service per her wishes.
