As the architectural designer and futurist best known for the geodesic dome, Buckminster Fuller enthralled a vast popular audience, inspired devotion from both the counterculture and the establishment, and was praised as a modern Leonardo da Vinci. His views on sustainability, as embodied in the image of Spaceship Earth, convinced him that it was possible to provide for all humanity through the efficient use of planetary resources. From Epcot Center to the molecule named in his honor as the buckyball, Fuller’s legacy endures to this day, and his belief in the transformative potential of technology profoundly influenced the founders of Silicon Valley. Drawing on meticulous research, dozens of interviews, and thousands of unpublished documents, Nevala-Lee has produced a riveting portrait that transcends the myth of Fuller as an otherworldly generalist.
