Year of discovery 1971

Breeder 1 is the first breeder, and in fact the first pattern to exhibit quadratic growth, that was found in Conway's Game of Life. It was found by Bill Gosper[1] no later than September 1971,[2] and is a puffer that produces Gosper glider guns. Many smaller patterns, known as spacefillers, have since been found that grow quadratically more quickly.

Breeder 1 at generation 1000. Gosper glider guns are produced to the east, emitting gliders streams above them
