BaySide Cannery (sometimes identified as Bayside or Bay Side) was the third largest cannery in the United States in the 1920s. It was owned by Thomas Foon Chew, a Chinese immigrant to California.
Thomas Foon Chew was born in the late 1880s in China and came to San Francisco with his mother and his father in 1897. How this was possible, following the implementation of the Chinese Exclusion Act in 1882, we don't know.
