R. Buckminster Fuller was a 20th century inventor, mathematician and futurist.

Philosophically he was concerned with meeting the needs of a growing global
civilization while reducing the use of natural resources; his inventions were meant to achieve those goals by simplifying and improving human housing and the objects
of daily life.

Never quite a mainstream figure, Fuller was viewed by some as an
impractical dreamer but embraced by others as a visionary genius. His most famous invention, the geodesic dome, uses a series of interlocking triangles to create a lightweight, sturdy dome which needs no internal supports.

Fuller coined the phrase "Spaceship Earth."
