Chinese Railroad Workers

Chinese railroad workers were integral to the building of railroads in California and across the country during the latter half of the 19th century. For many years the identities, experiences, and contributions, of these Chinese immigrants went largely unknown and unrecognized. Chinese Americans in California have worked to discover the histories of these workers, some with great success and some without. Join us for short presentations led by individuals who have discovered a family history relating to the building of the railroads in California, as well as those who have searched and not found what they were looking for. After the presentations, we will hold an session for questions and comments.

Featuring CGS member Grant Din with Albert Chen, Suzette Liang, and Sue Lee at the California Historical Society in San Francisco, this session is a co-production of CGS, the California Historical Society, and the Chinese Historical Society of America.

Thursday, April 18 at 6:00PM. Details and Registration
