The origin of the shmoo plot is unclear. A reference to shmoo plotting can be found in manuals for the [[IBM 2365 Processor Storage]],<ref>[https://www.staff.ncl.ac.uk/roger.broughton/museum/corestore/ram64k.htm 64KByte gate in a Core Storage Unit], Virtual Museum, [[Newcastle University]]</ref> for a computer which was installed in 1967.<ref>[https://www.staff.ncl.ac.uk/roger.broughton/museum/index.htm Virtual Museum], [[Newcastle University]]</ref>
The invention of the shmoo plot is credited to VLSI Hall Of Fame inductee [[Robert Huston]] (died 2006).<ref>[https://www.chiphistory.org/TCI%20All_Stars-Hall_of_Fame%20161212.pdf VLSIresearch’s CHIP MAKING INDUSTRY HALL OF FAME], VLSI Research Inc.</ref>▼
