Like most Huntington-themed place names in Southern California, this street honors railroad/streetcar baron Henry E. Huntington (1850-1927; see Huntington Drive for a bio). It was laid out in 1906 on the Ramona Acres tract, which Huntington himself had nothing to do with. The Emerson Realty Company, who didn’t own the tract but promoted the hell out of it, surely named its streets (hence Emerson Avenue). Huntington Avenue’s name was thus part of Emerson’s marketing scheme: ads claimed that Ramona Acres was “within a few feet” of Huntington’s upcoming railway to Covina and that “H.E. Huntington has purchased nearly every inch of land adjoining this property.” Safe to say those ads stretched the truth a little.
