Visionary American architect, inventor, writer, and philosopher (1895–1983) perhaps best known for inventing the geodesic dome, one of the signal developments in modern design and engineering. A family of complex carbon molecules with structures reminiscent of the geodesic dome were named fullerenes—aka “Bucky ball”—in his honor. ALS signed “Bucky,” one page, 8.5 x 11, personal Southern Illinois University letterhead, July 31, 1963. Fuller writes to Nathan Resnick at Long Island University.
