Gerald Stanford "Gerry" Guralnik (/ɡʊˈrælnɪk/; September 17, 1936 – April 26, 2014) was the Chancellor’s Professor of Physics at Brown University. In 1964 he co-discovered the Higgs mechanism and Higgs boson with C. R. Hagen and Tom Kibble (GHK).^{[2][3][4][5][6][7]} As part of Physical Review Letters' 50th anniversary celebration, the journal recognized this discovery as one of the milestone papers in PRL history.^[8] While widely considered to have authored the most complete of the early papers on the Higgs theory, GHK were controversially not included in the 2013 Nobel Prize in Physics.^{[9][10][11][12][13][14][15][16]}

In 2010, Guralnik was awarded the American Physical Society's J. J. Sakurai Prize for Theoretical Particle Physics for the "elucidation of the properties of spontaneous symmetry breaking in four-dimensional relativistic gauge theory and of the mechanism for the consistent generation of vector boson masses".^[17]

Guralnik received his BS degree from the Massachusetts Institute of Technology in 1958 and his PhD degree from Harvard University in 1964.^[18] He went to Imperial College London as a postdoctoral fellow supported by the National Science Foundation and then became a postdoctoral fellow at the University of Rochester. In the fall of 1967 Guralnik went to Brown University and frequently visited Imperial College and Los Alamos National Laboratory where he was a staff member from 1985 to 1987. While at Los Alamos, he did extensive work on the development and application of computational methods for lattice QCD.

Guralnik died of a heart attack at age 77 in 2014.^[19][20][21]
