Mock Duck, leader of Hip Sing Tong organization in Chinatown, New York City, New York

In the 19th century, a majority of Chinese immigrants were single men who worked for a while and returned home. At first, they were attracted to North America by the gold rush in California. A relatively large group of Chinese immigrated to the United States between the start of the California gold rush in 1849 and 1882, before federal law stopped their immigration. After the gold rush, Chinese immigrants worked as agricultural laborers, on railroad construction crews throughout the West, and in low-paying industrial jobs. Soon, many opened their own businesses such as restaurants, laundries, and other personal service concerns. With the onset of hard economic times in the 1870s, European immigrants and Americans began to compete for the jobs traditionally reserved for the Chinese. Such competition was accompanied by anti-Chinese sentiment, riots, and pressure, especially in California, for the exclusion of Chinese immigrants from the United States. The result was the Chinese Exclusion Act, passed by Congress in 1882. This Act virtually ended Chinese immigration for nearly a century.

The New York World-Telegram, later known as the New York World-Telegram and The Sun, was a New York City newspaper from 1931 to 1967. The Library of Congress collection includes about 1 million photographs that the New York World-Telegram & Sun Newspaper assembled mostly 1890 and 1967, the year in which the newspaper closed. This newspaper photo morgue is typical of the files that newspapers maintain of images that either were published or were believed to have some future publication potential. Such files were periodically "weeded" by newspaper staff members. Much of the photography used by newspapers is "quick copy," and many images have been cropped, retouched, or highlighted for publication. Some images were taken by the newspaper's staff photographers while others came from wire press services, studios, or amateur photographers.
