Ah Louis traveled from his home in Guangdong Province, Greater Taishan Region, China, and arrived in California between 1856 and 1861 in order to strike it rich during the California Gold Rush. Unsuccessful at mining, he became a laborer working in Corvallis, Oregon and points further south. Wong eventually settled in San Luis Obispo, California in 1870, and was working as a cook in a hotel there in 1871. Soon he began to organize work-crews to help construct the Pacific Coast Railroad, delivering 160 Chinese Americans from San Francisco by schooner. In 1877, Ah Louis was awarded two large road construction contracts, including a road from Paso Robles, California to Cambria, California and the first stages of a road connecting San Luis Obispo to Paso Robles, California. In 1884, Wong received the contract to construct the four Cuesta Grade tunnels for the Southern Pacific Railroad's coast route, requiring the provision of 2,000 laborers and taking ten years to complete.
Store
Seeing a need for the California Central Coast's Chinese community, Ah opened a small East Asian mercantile in 1874, the first in San Luis Obispo County, from which he sold goods, including rice, rum, and opium. The wooden structure was replaced by a sturdy brick building in 1885, made from bricks from his own brickyard, at 800 Palm Street on the corner of Chorro Street in downtown San Luis Obispo, marking where San Luis Obispo's Chinatown once stood. The shop is currently owned by Dr. William Watson, MD, Ah Louis's great-grandson, and the ground floor is now operated as a retail store. The Ah Louis store has been designated as a California State Historical Landmark number 802; and recognized by the United States National Park Service being also listed on the National Register of Historic Places.
Family
Ah Louis married his first wife in China in 1860. She was in California in 1868, but returned to China about 1873. Wong last saw her in China in 1888. The 1880 census shows a wife living with him, but no children are shown. In May 1889, Ah Louis married Eng Gon Ying in San Francisco. Together they raised their eight children in their residence above the Ah Louis Store. ;Louis Children In 1909 Eng Gon Ying Louis was murdered by Willie Wong, Ah Louis' son from his first marriage. In December 1932, accompanied by sons Fred and Howard, Ah Louis returned to China, intending to visit family and to follow the tradition of dying where one was born. Disappointed with the lack of progress and modern technology and the high rate of banditry, Ah decided to return to San Luis Obispo. He died on December 18, 1936. The youngest and last surviving of Ah Louis' children, Howard Louis, who had a degree in economics and fought with Gen. George Patton, continued to run the store until the late 1990s and died on August 15, 2008, at the age of 100. The store was damaged from the San Simeon earthquake in 2003 and afterwards condemned by the City of San Luis Obispo. Around this time, the store was fully acquired by William J. Watson, MD, who restored the building and its interior. It was placed on the National Register of Historic Places in 2008.
