Puffer 1 was the first puffer to be found, and was discovered by Bill Gosper in 1971. The debris that it leaves behind are groups of four blinkers and a pair of bookends, as shown below. The debris can be cleaned up and converted into gliders to create a rake as in backrake 3.

Puffer 1 first appeared semi-naturally in March 2016.[1] Before this, a puffer with a similar construction but a different ash and period appeared in a soup found by Richard Schank in December 2014.[2]
