Historically, the first true GUT, which was based on the [[simple Lie group]] {{math|[[SU(5)]]}}, was proposed by [[Howard Georgi]] and [[Sheldon Glashow]] in 1974.<ref>{{cite journal |last1=Georgi |first1=H. |last2=Glashow |first2=S.L. |s2cid=9063239 |date=1974 |title=Unity of All Elementary Particle Forces |journal=[[Physical Review Letters]] |volume=32 |issue=8 |pages=438–41 |doi=10.1103/PhysRevLett.32.438|bibcode=1974PhRvL..32..438G}}</ref> The [[Georgi–Glashow model]] was preceded by the [[semisimple Lie algebra]] Pati–Salam model by [[Abdus Salam]] and [[Jogesh Pati]] also in 1974,<ref>{{cite journal |last1=Pati |first1=J. |last2=Salam |first2=A. |date=1974 |title=Lepton Number as the Fourth Color |journal=[[Physical Review D]] |volume=10 |issue=1 |pages=275–89 |doi=10.1103/PhysRevD.10.275 |bibcode = 1974PhRvD..10..275P }}</ref> who pioneered the idea to unify gauge interactions.

The acronym GUT was first coined in 1978 by CERN researchers [[John Ellis (physicist, born 1946)|John Ellis]], [[Andrzej Buras]], [[Mary K.
