Best of Friends is an informal, close-up biography of the friendship between Buckminster Fuller (1895–1983) and Isamu Noguchi (1904–1988). Author Shoji Sadao, who was a friend and business partner to both, chronicles the deep and abiding respect, affection, and support they had for one other. Fuller’s development of his Dymaxion Map, Geodesic geometry, and the Dymaxion Car are discussed in detail as are Noguchi’s multi-faceted career as sculptor, landscape architect, industrial designer, and dance set designer, an artist without borders who challenged the artificial opposition between the fine and applied arts. Sadao’s role as partner to both offered him privileged access to details unavailable to others.
