by 1936; popular from 1969 (with added pig (n.) by 1970); a specialized use of chauvinism, which in late 19c. international Communist Party jargon was extended to racism and in the next generation to sexism:
In this era, inspired by the CP's struggle against racism, women in the CP coined the term male chauvinism, in a parallel with white chauvinism, to derogate the conviction of men that they were better than women. [Jane Mansbridge and Katherine Flaster, "Male Chauvinist, Feminist, and Sexual Harassment, Different Trajectories in Feminist Linguistic Innovation," "American Speech," vol. lxxx, no. 3, Fall 2005]
Related: Male-chauvinism (1969).
1840, "exaggerated, blind nationalism; patriotism degenerated into a vice," from French chauvinisme (1839), from the character Nicholas Chauvin, soldier of Napoleon's Grand Armee, who idolized Napoleon and the Empire long after it was history, in the Cogniards' popular 1831 vaudeville "La Cocarde Tricolore." The meaning was extended to "excessive belief in the superiority of one's race" in late 19c. in communist jargon, and to (male) "sexism" in late 1960s via male chauvinist (q.v.).
The surname is a French form of Latin Calvinus and thus Calvinism and chauvinism are, etymologically, twins. The name was a common one in Napoleon's army, and if there was a real person at the base of the character in the play, he has not been certainly identified by etymologists, though memoirs of Waterloo (one published in Paris in 1822) mention "one of our principal piqueurs, named Chauvin, who had returned with Napoleon from Elba," which action implies the sort of loyalty displayed by the theatrical character.
c. 1200, persoun, "an individual, a human being," from Old French persone "human being, anyone, person" (12c., Modern French personne) and directly from Latin persona "human being, person, personage; a part in a drama, assumed character," originally "a mask, a false face," such as those of wood or clay, covering the whole head, worn by the actors in later Roman theater. OED offers the general 19c. explanation of persona as "related to" Latin personare "to sound through" (i.e. the mask as something spoken through and perhaps amplifying the voice), "but the long o makes a difficulty ...." Klein and Barnhart say it is possibly borrowed from Etruscan phersu "mask." De Vaan has no entry for it.
From mid-13c. as "one of the persons of the Trinity," a theological use in Church Latin of the classical word. Meanings "one's physical being, the living body; external appearance" are from late 14c. In grammar, "one of the relations which a subject may have to a verb," from 1510s. In legal use, "corporate body or corporation other than the state and having rights and duties before the law," 15c., short for person aggregate (c. 1400), person corporate (mid-15c.).
The use of -person to replace -man in compounds for the sake of gender neutrality or to avoid allegations of sexism is recorded by 1971 (in chairperson). In person "by bodily presence" is from 1560s. Person-to-person is attested by 1919, originally of telephone calls.
