Richard Buckminster Fuller (; July 12, 1895 – July 1, 1983) was an American architect, systems theorist, author, designer, inventor, and futurist. Fuller published more than 30 books, coining or popularizing terms such as "Spaceship Earth", "Dymaxion" (house, car, map...), ephemeralization, synergetic, and "tensegrity". He also developed numerous inventions, mainly architectural designs, and popularized the widely known geodesic dome. Carbon molecules known as fullerenes were later named by scientists for their structural and mathematical resemblance to geodesic spheres.
Fuller was the second World President of Mensa from 1974 to 1983.
