The Brout-Englert-Higgs boson

Why is the Brout-Englert-Higgs boson is commonly called the Higgs boson? Here is Steven Weinberg's version of the story:

“In his recent book, The Infinity Puzzle (Basic Books, 2011), Frank Close points out that a mistake of mine was in part responsible for the term “Higgs boson.” In my 1967 paper on the unification of weak and electromagnetic forces, I cited 1964 work by Peter Higgs and two other sets of theorists. (...) As to my responsibility for the name “Higgs boson,” because of a mistake in reading the dates on these three earlier papers, I thought that the earliest was the one by Higgs, so in my 1967 paper I cited Higgs first, and have done so since then. Other physicists apparently have followed my lead. But as Close points out, the earliest paper of the three I cited was actually the one by Robert Brout and François Englert. In extenuation of my mistake, I should note that Higgs and Brout and Englert did their work independently and at about the same time, as also did the third group (Gerald Guralnik, C.R. Hagen, and Tom Kibble). But the name “Higgs boson” seems to have stuck.” (As to the last sentence, let us recall, however, that Guralnik, Hagen, and Kibble do quote in their 1964 paper the works of Brout-Englert and Higgs).

CERN, 4 juillet 2012:

The 47th "Rencontres de Moriond" particle physics meeting took place in La Thuile, Italy. On Wednesday March 7th, a session on "Electroweak symmetry breaking" was dedicated to the search for the (Brout-Englert-Higgs) Scalar boson, with the latest results from Tevatron (DZero and CDF), and LHC (Atlas, CMS). The session was opened by François Englert giving a personal vision of the breaking mechanisms, and concluded with an extended discussion, structured by a compilation of the salient results by Jean-François Grivaz.
