Attending to the tropological imagination of Progressive Era U.S. immigration, this chapter maps what Michel Foucault calls “the organization of ‘erotic zones’ in the social body” to narrate a queer history of the social body itself. In so doing, the chapter animates a variety of period figurations of mass immigration—including racial indigestion and race suicide—to trace a new genealogy of the literary erotics of Asian, Italian, and Jewish immigrants, the ethnic groups that most threatened the whiteness of the social body. Reading across representations of immigration in the works of Henry James, Israel Zangwill, Charles Warren Stoddard, Yone Noguchi, Sui Sin Far, Jennie June, Emanuel Carnevali, and Emma Lazarus, this chapter shifts the history of sexuality from one located in individual bodies to theorize a sexuality of the population.
