Juan Rodriquez Cabrillo discovered the "Bay of Smokes." The south-facing San Pedro Bay was originally a shallow
mudflat, too soft to support a
wharf. Visiting ships had two choices: stay far out at anchor and have their goods and passengers ferried to shore, or beach themselves. That sticky process is described in
Two Years Before the Mast by
Richard Henry Dana Jr., who was a crew member on an 1834 voyage that visited San Pedro Bay.
Phineas Banning greatly improved shipping when he
dredged the channel to Wilmington in 1871 to a depth of . The port handled 50,000 tons of shipping that year. Banning owned a stagecoach line with routes connecting San Pedro to
Salt Lake City, Utah, and
Yuma, Arizona, and in 1868 he built a railroad to connect San Pedro Bay to
Los Angeles, the first in the area. After Banning's death in 1885, his sons pursued their interests in promoting the port, which handled 500,000 tons of shipping in that year. The
Southern Pacific Railroad and
Collis P. Huntington wanted to create Port Los Angeles at
Santa Monica and built the
Long Wharf there in 1893. However, the
Los Angeles Times publisher
Harrison Gray Otis and
U.S. Senator Stephen White pushed for federal support of the Port of Los Angeles at San Pedro Bay. The
Free Harbor Fight was settled when San Pedro was endorsed in 1897 by a commission headed by Rear Admiral
John C. Walker (who later went on to become the chair of the
Isthmian Canal Commission in 1904). With U.S. government support,
breakwater construction began in 1899, and the area was annexed to Los Angeles in 1909. The Los Angeles Board of Harbor Commissioners was founded in 1907. In 1912 the
Southern Pacific Railroad completed its first major wharf at the port. During the 1920s, the port surpassed
San Francisco as the West Coast's busiest seaport. In the early 1930s, a massive expansion of the port was undertaken with the construction of a breakwater three miles out and over two miles in length. In addition to the construction of this outer breakwater, an inner breakwater was built off
Terminal Island with docks for seagoing ships and smaller docks built at Long Beach. It was this improved harbor that hosted the
sailing events for the
1932 Summer Olympics. During
World War II, the port was primarily used for shipbuilding, employing more than 90,000 people. In 1959,
Matson Navigation Company's Hawaiian Merchant delivered 20 containers to the port, beginning the port's shift to
containerization. The opening of the
Vincent Thomas Bridge in 1963 greatly improved access to
Terminal Island and allowed increased traffic and further expansion of the port. In 1985, the port handled one million containers in a year for the first time. ==Port district==
