Heart is a period-5 oscillator that is shown as the sixth pattern in the first row of Jason Summers' main period 5 collection. It was found by Robert Wainwright in January 1982 and independently discovered by David Buckingham on August 15, 1984.^[1] A 15-glider synthesis was discovered by Jason Summers in November 2004^[2] for a stator variant of this oscillator in which each side is stabilized by two blocks instead of a tub.

A four-fold version of this oscillator appeared semi-naturally in November 2014 in a soup found by Richard Schank.^[3] A monomerized version later appeared in an asymmetric soup in May 2016.^[4]
