The history of Duarte

The area at the foot of the San Gabriel Mountains has been inhabited for more tha ten thousand years. When the Spanish explored the region in the 1600s, they met the local "Tongva" natives, which they called Gabrielino (Gabrieleño) after the San Gabriel Arcángel Mission which they founded nearby in 1771.

The Mission owned a large area of land which after Mexico's independence from Spain (1821) eventually became fiscal land which was granted to local citizens. The Governor Juan Alvarado granted a 6,596-acre (2.670 ha.) tract to Andrés Duarte (1805-1863), a former military, in 1841 which became known as the Rancho Azusa de Duarte.

Duarte built a home in adobe on what is now Tocino Drive.

After Mexico lost California to the US during 1846-48 war, Duarte had to file a claim for the recognition of his grant under the 1848 Treaty of Guadalupe Hidalgo. He sold parts of his land to pay the legal costs and back taxes. The ranch was finally awarded to him in 1878, but by then the whole ranch had been sold.

The new landlords owned 40-acre plots and grew citrus on them.

The Santa Fe railroad extended its line through Duarte in 1887, linking its main line in San Bernardino across the San Gabriel Valley and into Los Angeles.

The Name: Duarte

The city took its name from the Ranch which in turn was the surname of its owner, Andrés Duarte.

It means "the son of Edward", from the English saint born in 1004 and a Portuguese king (1391-1438). First recorded in writitng in 1509 in Vizcaya, Aragon.

National Old Trails Highway (N.O.T.) in Duarte

The 1915 survey conducted by the USGS along the Santa Fe railroad shows the station on the map, but said nothing about the town. At that time, the automobile had increased and the National Old Trails (N.O.T.) Association was formed to promote a modern highway link between New York and Los Angeles. In Duarte it followed the Foothill Blvd., and it appeared in a 1912 map, as Duarte on Foothill Blvd, followed by Monrovia (20 mi.) and further west Pasadena (10 mi.)

1926: Route 66 created

Route 66 was created in 1926 and it was aligned using the N.O.T. highway in California. It ran along Foothill Blvd. through Duarte. The 1935 Road map of Los Angeles, the 1939 map and The 1940s Caltrans road map shows Route 66 running west from Azusa, crossing the San Gabriel Wash, into Duarte and then Monrovia.

The 1939 "Guide to the Golden State" written by the WPA described the Duarte section of Route 66 as follows:

"The name of DUARTE, 31.9 m. (600 alt., 1,326 pop.), center of an old orange-growing district, commemorates Andreas Duarte, grantee of a 4,000-acre tract on the site, who constructed a ditch to bring water from San Gabriel Canyon for irrigation purposes."

Jack DeVere Rittenhouse rode the whole of Route 66 in 1946 and wrote his "...Guide Book to Highway 66" in which his entry of Duarte is merely one town among many: "More towns you pass through include LA VERNE at 336 mi., GLENDORA, 241 mi.; AZUSA, 343 mi., DUARTE, 347 mi.; MONROVIA, 350 mi., ....".

Route 66 was replaced by the freeway network in the mid 1950s and in 1964 it was officially bypassed in the San Gabriel Valley, but in 1966 Duarte and Fontana teamed up to try to have a large sign posted in San Bernardino proclaiming that Route 66 remained a through route into Los Angeles. They failed.

Alton Glenn Miller, the famous big band musician, composer, and bandleader in the swing era, built a house in Duarte where he planned to settle after World War II, he died in 1944 serving in France. The home burned down during a wildfire in 1980.

2444 E Huntington Dr., Duarte

The company was founded in 1945 in Monrovia by the Stueve Stueve brothers -Ed, Harold, and Elmer, and they became a "certified dairy" in 1953. They were against pasteurization and by the 1980s were the largest producer and distributor of "raw" (unpasteruized) milk in the U.S.

Health concerns about Salmonella led the California Sate Health Department to a long legal battle with Alta Dena and eventually the new owners stopped selling Stueve' Natural raw milk in 1999.

The company had, back in 1951, understood that Californians loved to do thins without having to get out of their cars, so he implemented the "cash and Carry" drive through dairy outlets like this one, which is now a market.

The Carmelite Sisters of the Most Sacred Heart of Los Angeles opened the Santa Teresita Rest Home in 1930 which is still open as an outpatient health care center.
