Dr. Isabella Aiona Abbott - The Seaweed Scientist

Dr. Isabella Aiona Abbott was a pioneering Native Hawaiian scientist who revolutionized marine botany and connected traditional knowledge with modern science.

Born Isabella Kauakea Yau Yung Aiona on June 20, 1919, in Hana, Maui. As a young girl, Dr. Abbott loved spending time by the ocean with her Native Hawaiian mother. Her mother taught her how to find and prepare edible seaweed, called limu. They collected it along the shore and used it in traditional Hawaiian meals. These early experiences didn’t just fill her belly; they sparked a lifelong passion for the ocean and its plants.

Algae, including seaweed, is far more important than most people realize. Through photosynthesis, algae create about 70% of the oxygen in Earth’s atmosphere, the air we breathe every day. Without algae, the ocean’s food chain would be very different, and life as we know it might not exist. Seaweed also provides homes and food for many marine animals, from fish and crabs to sea urchins and snails.

Today, scientists believe seaweed could help slow climate change by removing carbon from the air. It can also help repair damaged marine ecosystems and be used to make renewable fuels and eco-friendly plastics. Seaweed is healthy, full of vitamins and minerals, and delicious in many dishes. Thanks to Dr. Abbott’s work, seaweed went from being a traditional food to a key focus of global scientific research.

Dr. Abbott also broke barriers for women and Native Hawaiians in science. At age 31, she became the first Native Hawaiian woman to earn a Ph.D. in any science when she received her doctorate in botany from the University of California, Berkeley. In 1971, she made history again as the first woman, and first person of color, to become a faculty member in Stanford University’s biological sciences department. She had already taught there for more than ten years before earning the official title.

After retiring from Stanford in 1982, Dr. Abbott returned to Hawaii to teach at the University of Hawaii. She created a new undergraduate program in ethnobotany; the study of how different cultures use plants. In her famous book on Hawaiian seaweed, she wrote that she wanted to “demonstrate the vital link between Hawaiian plants and Hawaiian culture.” She did just that, uncovering traditional uses for seaweed and helping to reintroduce it into modern Hawaiian life.

Dr. Abbott worked closely with Hawaiian elders to preserve oral histories and knowledge of the ocean that were in danger of being forgotten. She helped turn this cultural knowledge into university courses so the next generation could carry it forward. She also spoke out for safe and respectful ocean practices, encouraging people to grow and harvest seaweed in ways that protect the environment.

Over her career, Dr. Abbott wrote nearly 200 books and articles about seaweed and algae. She discovered more than 200 new species, many of which now carry her name. She earned many honors, including the Darbaker Prize from the Botanical Society of America and a Lifetime Achievement Award from the Hawaii Department of Land and Natural Resources.

Dr. Isabella Abbott passed away in 2010 at the age of 91, in her home on Oahu near the ocean she loved so deeply. She left behind a legacy that continues to inspire scientists, environmentalists, and anyone who cares about protecting our natural world. Her passion for seaweed transformed science, honored Hawaiian traditions, and opened doors for women in research. Thanks to her, the study of seaweed is now recognized as essential for both the health of our planet and the future of our oceans.
