The Panama–Pacific International Exposition (PPIE) was a world's fair held in San Francisco, California, U.S., from February 20 to December 4, 1915. Its stated purpose was to celebrate the completion of the Panama Canal, but it was widely seen in the city as an opportunity to showcase its recovery from the 1906 earthquake. The fair was constructed on a 636 acre (2.6 km2) site along the northern shore, between the Presidio and Fort Mason, now known as the Marina District.


Among the exhibits at the Exposition was the C. P. Huntington, the first steam locomotive purchased by Southern Pacific Railroad; the locomotive then went on static display at the California State Railroad Museum in Sacramento. A telephone line was also established to New York City so people across the continent could hear the Pacific Ocean. The Liberty Bell traveled by train on a nationwide tour from Philadelphia, Pennsylvania, to attend the exposition.[1]

The 1915 American Grand Prize and Vanderbilt Cup auto races were held February 27 and March 6 on a 3.84-mile (6.18 km) circuit set up around the Exposition grounds.[2] The Smithsonian Institution also had an exhibition at the Exposition.[3]

Yumian (鱼面), meaning fish-noodle in Chinese, is a noodle made with flour and fish from the Fu River in Yunmeng, China. Yunmeng Yumian was awarded silver medal of the Panama-Pacific International Exposition.[4][5][better source needed]
