TheTongva inhabited the area before the city was established, andRancho Los Alamitos was known as the village ofPuvunga. The area is still sacred to the Tongva people.[8][9]
The town of Los Alamitos was established in 1896 byLewellyn Bixby to support a new sugar-beet factory built by the Clark brothers.William Andrews Clark, a future Senator from Montana, had built his fortune in mining, banking and logging in that state. His younger brother, J. Ross Clark, managed their operations in California after he moved there for health reasons. Lewellyn Bixby, whose family owned the surrounding land onRancho Los Cerritos and Rancho Los Alamitos, had been trying to build asugar beet factory in that area for several years. Due to financial losses during the 1880s, he no longer had the money to build the factory complex on his own. Bixby had made a fortune in the 1850s when he and cousins Benjamin and Thomas Flint formedFlint, Bixby & Co. to deal in mutton and wool onRancho San Justo, south of San Jose. After selling wool to the government during the Civil War, the Flints and Bixby bought land in southern California; this included the futureIrvine Ranch and Rancho Los Cerritos, which is much of the western half ofLong Beach. Flint, Bixby hired Lewellyn's younger brother, Jotham, to manage the Cerritos. When the company broke up, Lewellyn assumed their southern California properties, moved toLos Angeles and became the senior partner with Jotham.
Around 1881, cousin John W. Bixby wanted to purchaseRancho Los Alamitos with a consortium which included Lewellyn and Jotham and bankerIsaias W. Hellman. When John died on May 7, 1887,[11] the ranch was divided among the three families. The northern third, adjacent to the Rancho Los Cerritos (roughly north of present-day Orangewood Avenue), went to the Lewellyn-Jotham faction and became the Bixby Land Company. By the mid-1890s, after the crash following the 1880s land boom, this group was cash-poor and land-rich. After experimenting in northern California with sugar beets, the Bixbys agreed to provide the land and contracted with William A. Clark for capital; E.A. Dyer provided the expertise to build a sugar-beet factory. The community that grew up around the factory complex, with streets of company houses for workers and surrounding farms, was called Los Alamitos. During the early 1900s,sugar beets were delivered to a factory by horse and wagon. Economics, the elimination of a protective tariff, and a 1921 insect infestation reduced the sugar-beet crop in Orange County and ended the industry there and in Los Alamitos. William Clark and his brother H. Ross, who ran the Los Alamitos operation, received 1,000 acres (4.0 km2) east of the factory and purchased 8,000 acres (32 km2) north of the factory (primarily inRancho Los Cerritos) which becameLong Beach Airport,Long Beach City College, and the city ofLakewood. Clark and Hellman were also involved withE. H. Harriman,Henry Edwards Huntington, and theSouthern Pacific Railroad in southern California; the Clarks completed a railroad fromLos Angeles toSalt Lake City, with a desert stop inLas Vegas.

On land south of the factory (and present-day Orangewood Avenue), John Bixby's son Fred had a ranch to fatten cattle for slaughter and managed Hellman's land in present-daySeal Beach). Bixby allowed European-immigrant,Mexican, andJapanese farmers to rent land and grow crops. At the beginning ofWorld War II, the Japanese farmers were rounded up by the military and relocated to internment camps inManzanar and elsewhere.
Before and early in the war, the area around Los Alamitos became a center of the aircraft industry. The Clark heirs arranged for Donald Douglas to begin construction of theDouglas Aircraft Company plant north of the Long Beach airport, and theNavy needed an auxiliary airfield for its reserve training facility at the airport. A touch-and-go field was built on level ground east of Los Alamitos in August 1940, Orange County's first military post. In February 1941, the Navy moved its reserve aviation training from Long Beach and purchased 1,300 acres (5.3 km2). Trainees and other troops began using the new facilities in November of that year, and Naval Reserve Air Base Long Beach moved its operations to NRAB Los Alamitos in May 1942. NRAB Los Alamitos was the nation's busiest reserve air base during theKorean War, but suburban residential development began to curtail its activity by the late 1950s. The Navy moved out in 1972, and the California National Guard took over management of the base as an Armed Forces Reserve Center the following year. It is a reserve support center for units of the Army, Navy, National Guard and Marines and home to other government agencies, including Homeland Security, FEMA and the State of California Office of Emergency Services.[12]
Former military personnel remained in Los Alamitos after the war, living in neighborhoods such as Carrier Row (whose streets are named for World War IIaircraft carriers,. Carrier Row was three small subdivisions, built in 1947–48, 1950, and 1955 by different builders. The first subdivision was Alamos Ranchos, first occupied in April 1948. The homes had sewage problems, and the builder stopped after completing the two blocks east of Lexington and south of Katella. In 1950, two more blocks were constructed as Plainview Homes. In 1955, the tract was completed with the construction of Los Alamitos Park. Los Alamitos Terrace, a 193-unit subdivision, was built north of Old Town West on a Bixby-operated dairy farm whose headquarters was present-day Los Alamitos High School.[12]
In 1956,Ross Cortese purchased land to build thewalled community ofRossmoor southwest of Los Alamitos. Rossmoor, Orange County's largest single development, was the first walled community in the United States and home to over 10,000 upper-middle-class professionals. Rossmoor's homes were initially designed by Earle G. Kaltenbach, and two later phases were designed by Chris Choate. Ranch-style homes dominated 1950s suburban architecture. Before Rossmoor, Choate and May worked with Cortese on the nearbyLakewood Rancho Estates in Long Beach.[12]
Although Rossmoor is not part of Los Alamitos, they have become linked. When Los Alamitos was incorporated, its population was about 3,400; Rossmoor's population was almost 10,000. Los Alamitos is slightly larger, with a population of over 11,000. Rossmoor's success led to the Los Alamitos subdivisions of Dutch Haven (1960), Rossmoor Highlands (1961), and Suburbia, New Dutch Haven, Greenbrook and College Park North (1967). Los Alamitos has been the hometown for a number of noted athletes, including baseball Hall of FamerBob Lemon (although he spent more time in Long Beach), and Olympic gymnastCathy Rigby. The Los Alamitos youth baseball leagues, which began in 1958 as the Rossmoor Little League and (after moving its fields to the Navy base) changing its name to Los Alamitos Youth baseball), developedAndy Messersmith. During the late 1980s, six former league players were playing major-league baseball:Robb Nen,J. T. Snow,Greg Harris,Dennis Lamp,Greg Pirkl, andMike Kelly. The area has been home to long-distance swimmerLynne Cox, California Supreme Court Chief JusticeMalcolm M. Lucas, and mystery writerJan Burke.
