No source is given for this statement, but this statement seems to be the source for every future history book. In a 2011 California history book the story is stated as:
The first recorded use of oil from this area was in 1850 when Andres Pico, Mexican general and brother of Pio Pico, the last Mexican Governor of California, collected seepage in Pico Canyon, several miles west of US 6, and distilled it in a copper still and worm to obtain petroleum for the lamps at San Fernando Mission.Between 1884 and 2011, almost all books that I have checked have more or less the same Pico story with different embellishments. Interestingly, most start out with "it is said that" or "there is a legend" - nothing very certain.
In the early fifties - authorities differ as to the exact date - Pico collected this oil and distilled it in a copper still and worm, making burning oil for the Mission, where there may have been seventy-five or a hundred souls, all told. This included the retainers with which every well-to-do Californian loved to surround himself, Mexicans employed on the ranch, and Mission Indians who still lingered after the Fathers departed, some too young to be of service, but all welcome to remain.The source given was "Petroleum in Southern California", 1913, by Paul Prutzman (California State Mining Bureau Bulletin 63) on page 159, where it says "As early as 1850 Andreas Pico had been collecting seepage oil, which he distilled with a copper still and worm, making burning oil for the San Fernando Mission." Prutzman's source was obviously the 1884 Fourth Annual Report. Frederick did some filling in between the lines.
Yet old records reveal that, several years before the Drake Well was drilled , two enterprising Spanish Californians, Andreas and Romulo Pico, were gathering "brea" as they called the sticky tar seeping into pits they dug in Southern California, and cooking the stuff at San Fernando Mission to boil off lamp oil and make axle grease.They also give no source for these "old records" and have no bibliography.
The padres who founded the California chain of missions and the early Spanish Californians knew about the tar, which they called brea, from their contacts with the Indians. They made little use of brea, though at some of the missions the padres and their Indian workers did cook off a light oil which they used in lamps in place of whale oil, then quite scarce. Only at San Fernando, Santa Barbara, and Ventura missions did these primitive distilling operations grow to commercial ventures.
About 1855, General Andreas Pico, brother of Pio Pico, the last Mexican governor of California, set up a crude still at San Fernando that extracted axle grease, lamp oil, and medicine oil from the tar he and his nephew hauled out of the hills from near Newhall.
There is also a similar story from the Sacramento Daily Union of March 31, 1865. This has parties in town, with no mention of Andres Pico (but he was probably there since he was an important person in Los Angeles), experimenting on crude oil from Pico and Wiley Springs. If Pico was already the "pioneer" refiner, then why didn't they just have him show them what to do?
He lived in a luxurious style and had a large household of trained servants, chiefly Indians. Like the grandee that he was, he entertained lavishly. His silver and china table service made a brilliant display. His household furnishings were plain but massive and luxurious. The plain old mission furniture was retained but many an expensive and more ornate piece had been added. His table afforded an ample style of living; the dinners consisted of five to six courses - all of the far-famed California-Spanish cookery, which no nation - not even the French, has ever excelled. Two young Indian boys served as waiters. They were clad in the simple tunic of Andres, at the head of the table and said grace, and at the close of the meal, the other took his place and returned thanks. At the mid-day and evening meals, and on the veranda in the evening, we were delightfully entertained by native musicians who played on three stringed instruments then mostly in vogue - the harp, violin and guitar.There is no mention of how the room was lit. Surely, the unheard of use of refined oil for lighting would have been reported by a visitor. I also checked many other books and newspaper articles of this period mentioning Pico or the mission and none of them said anything about refining oil at the mission. Maybe somebody confused olive oil with petroleum. They did have stills for making olive oil, wine, and brandy.
Long after the oil industry in California had become a reality, a few tales were told of experiments in oil refining as early as the middle 1850's by various southern Californians. The best known of these concerns Don Andres Pico, who, it is claimed [in the fourth report of 1884], tapped the oil springs of Pico Canyon in the Santa Susana Mountains as early as 1855 and "made oil for the San Fernando Mission ...in a copper still and worm." The truth is that the mission was by this time in ruins, except for a building Andres occupied. The last Franciscan padre had left the premises nearly a decade before. It is highly doubtful that such experiments actually occurred, and if any did, it was merely as a small-scale, isolated episode.In 1984 W.H. Hutchinson in his book "California, The Golden Shore by the Sundown Sea" came to the same conclusion:
There is a claim that Andres Pico distilled petroleum into illuminating oil at Mission San Fernando as early as 1854-55. Extensive research into the beginnings the oil industry in California does not confirm this story, and it seems best to consign it to the realm of folklore.
