Emanuele Quercigh (born 1934 in Naples, Italy) is an Italian particle physicist who works since 1964 at CERN, most known for the discovery of quark-gluon plasma (QGP).

In 1964 Quercigh moved to Geneva, Switzerland, where he took up a position as fellow at CERN and subsequently became a staff physicist.

Then he proposed and led, together with David Lord, the ERASME project, a machine for scanning and measuring film from BEBC.

[3][4] As of 1979 Quercigh was the leading scientist for various CERN SPS experiments using the Omega Spectrometer, a facility he promoted with colleagues already in 1968,[5] studying quantum chromodynamics (QCD) processes, hadron spectroscopy and particle and soft photon production mechanisms.

[14] When CERN announced the observation of the QGP in February 2000,[15] he presented the strange particle production results on behalf of these collaborations.
