Breeder 1

Breeder 1, or lobster, 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 in the early 1970s[1], and is a puffer that produces Gosper glider guns. Many smaller patterns, known as spacefillers, have since been found that grow quadratically more quickly.
