Eater 1 (or fishhook or simply eater) was the first discovered eater. Its ability to eat various objects was discovered by Bill Gosper in 1971. It is the smallest still life that is neither radially symmetric nor symmetric through a line, and it is the thirteenth most common still life, being less common than mango but more common than long barge.[1]
It is extremely useful as an eater because in addition to being able to eat gliders, it can also eat blinkers, loaves, pre-beehives, lightweight spaceships, and many other common patterns. It only takes four generations to recover from being hit by a glider, and it is the smallest glider eater.
Its pre-beehive eating reaction is used in the period 12 oscillator dinner table.
