Writer Alvin Toffler once described architect, theorist, designer, and futurist Buckminster Fuller (July 12, 1895–July 1, 1983) as “one of the most-powerful myth-makers and myth-exposers of our time … a controversial, constructive, endlessly energetic metaphor-maker who sees things differently from the rest of us, and thereby makes us see ourselves afresh” — perhaps the richest and most accurate account of a mind to whom we owe more than we realize.
