Ah Louis, native of Canton, China, set up one of the first kilns in the San Luis Obispo area for making
bricks about 1885. His brickyard was located one mile west of San Luis Obispo on the road to Bishop's
Peak. Surficial loam was hand-molded into bricks and air dried. Bricks were fired in open kilns. Wood was used
as fuel. In 1896, eight Chinese workers made 800,000 bricks per year for the local market. Good examples
of this brick can be seen in the Ah Louis Store at Palm and Chorro streets, Railroad Square Building at 1800
Santa Barbara St., Carnegie Library, and the Johnson Building, San Luis Obispo. His bricks were
also used in the South Pacific Coast Railway roundhouse, courthouse, and east wing of the mission. Ah Louis
ceased making bricks about 1906.
