Though notorious for its polluted air today, the city of Los Angeles once touted itself as a health resort. After the arrival of the transcontinental railroad in 1876, publicists launched a campaign to portray the city as the promised land, circulating countless stories of miraculous cures for the sick and debilitated. As more and more migrants poured in, however, a gap emerged between the city ?s glittering image and its dark reality. Emily K. Abel shows how the association of the disease with ?tramps ? during the 1880's and 1890's and Dust Bowl refugees during the 1930's provoked exclusionary measures against both groups. In addition, public health officials sought not only to restrict the entry of Mexicans (the majority of immigrants) during the 1920's but also to expel them during the 1930's. Abel ?s revealing account provides a critical lens through which to view both the contemporary debate about immigration and the U.S. response to the emergent global tuberculosis epidemic.
