Cemetery in California oilfield produced royalty checks for next of kin.
In the summer of 1921, the Signal Hill oil discovery would help make California the source of one-quarter of the world’s entire oil output. Soon known as Porcupine Hill, the town’s Long Beach oilfield produced about 260,000 barrels of oil a day by 1923.
The Alamitos No. 1 well, drilled on a remote hilltop south of Los Angeles, erupted a column of “black gold” on June 23, 1921. Natural gas pressure was so great that the oil geyser climbed 114 feet into the air.
After the June 1921 oilfield discovery, Signal Hill had so many derricks that people called it Porcupine Hill. Circa 1935 postcard courtesy Boston Public Library, Digital Commonwealth.
The oilfield discovery well, which produced almost 600 barrels a day, would eventually produce 700,000 barrels of oil. Signal Hill incorporated three years after its Alamitos discovery well made headlines.
In 1923, Signal Hill’s petroleum field produced more than 68 million barrels of oil. The Signal Hill community later became one of the first U.S. cities to be completely surrounded by another city, Long Beach.
Signal Hill, a residential area before the 1921 discovery of the Long Beach oilfield, became covered in derricks. “Today you can see wonderful commemorative art displays of this era throughout the lush parks and walkways of Signal Hill,” notes a local newspaper.
By the 2000s, more than one billion barrels of oil were pumped from the Long Beach oilfield since the original 1921 strike. “Signal Hill is the scene of feverish activity, of an endless caravan of automobiles coming and going, of hustle and bustle, of a glow of optimism,” reported California Oil World.

“Derricks are being erected as fast as timber reaches the ground,” the magazine adds. “New companies are coming in overnight. Every available piece of acreage on and about Signal Hill is being signed up.”
Signal Hill helped make California the source of one-quarter of the world’s oil. “Porcupine Hill” and the Long Beach field produced 260,000 barrels of oil a day by 1923.
Within a year, Signal Hill — before and after a residential area — will have 108 wells, producing 14,000 barrels of oil a day. There were so many derricks, people started calling it Porcupine Hill. “Derricks are so close that on Willow Street, Sunnyside Cemetery graves generated royalty checks to next-of-kin when oil was drawn from beneath family plots,” noted one historian.

Dave Summers explained in his 2011 article, “The Oil Beneath California,” that when oilfields around Los Angeles began to develop, “Californian production became a significant player on the national stage.” The OilPrice.com article continued:
By 1923 it was producing some 259,000 barrels per day from some 300 wells, in comparison with Huntington Beach, which was then at 113,000 barrels per day and Santa Fe Springs at 32,000 barrels per day… And, in a foreboding of the future problems of overproduction, this was the first year in a decade that supply exceeded demand.
Shell Oil Geologists
Signal Hill oil potential had drawn wildcatters south of Los Angeles since 1917 but with no success. Two Royal Dutch Shell Oil Company geologists and a driller persevered.
“This was a great exploit and economic risk for the time. Shell Oil Company had just lost $3 million at a failed drilling site in Ventura, five years before,” reported a Long Beach newspaper.
The Alamitos No. 1 well and its monument dedicated on May 3, 1952, “as a tribute to the petroleum pioneers for their success here…”
Although another “dry hole” would be expensive, Shell geologists Frank Hayes and Alvin Theodore Schwennesen spudded their well in March 1921. Driller O.P. “Happy” Yowells believed oil lay deeper than earlier “dusters” had attempted to reach.
By summer, the steam-powered cable tool rig had Yowells close to making oilfield history. On June 23, 1921, at a depth of 3,114 feet, his wildcat well for Shell Oil erupted, revealing a petroleum reserve that extended to nearby Long Beach.
According to the Paleontological Research Institution, Signal Hill became the biggest oil field the already productive Southern California region had ever seen. This made California, “the nation’s number-one producing state, and in 1923, California was the source of one-quarter of the world’s entire output of oil!”
Decades before Signal Hill, another giant Southern California oilfield had been discovered in 1892. A struggling prospector drilled into tar seeps he found near present-day Dodger Stadium (see Discovering Los Angeles Oilfields).
Signal Hill Oil Park
Today, Signal Hill’s Discovery Well Park includes a community center to educate the public. Historic photos and descriptions can be found at six viewpoints along the Panorama Promenade. There are producing oil wells throughout the hill — with the historic “Discovery Well, Alamitos Number 1” at the corner of Temple Avenue and East Hill Street.
A monument dedicated on May 3, 1952, serves “as a tribute to the petroleum pioneers for their success here, a success which has, by aiding in the growth and expansion of the petroleum industry, contributed so much to the welfare of mankind.”
Visitors to the area can see “wonderful commemorative art displays of this era throughout the lush parks and walkways of Signal Hill,” reported the Long Beach Beachcomber. Dedicated on September 30, 2006, the statue “Tribute to the Roughnecks” can be found on Skyline Drive.
Cindy Jackson ‘s “Tribute to the Roughnecks” atop Signal Hill with Long Beach is in the distance. Signal Hill Petroleum Chairman Jerry Barto and Shell Oil employee Bruce Kerr were models.
The first California oil wells were drilled near oil seeps in the northern part of the state around the time of the Civil War. These Pico Canyon wells produced limited amounts of crude oil, but there was no market for the oil. Larger oilfields would be revealed in the early 1890s about 35 miles to the south.
Earlier explorers noted evidence of California’s petroleum fields by the large number of oil seeps, both onshore and offshore. California’s first commercial oil well in 1876 was drilled in Pica Canyon, well known for its asphalt seeps.
Between 1913 and 1923 Hollywood used the derricks on Signal Hill in movies starring Buster Keaton and Fatty Arbuckle. In 1957, what many consider the world’s first “all jazz” radio station, KNOB (now KLAX), first transmitted from a small studio on top of the historic oil hill.

Less than 10 months after Edwin L. Drake and his driller William “Uncle Billy” Smith completed the first commercial U.S. oil well on August 27, 1859, along Oil Creek in Titusville, Pennsylvania, Thomas A. Gale wrote a detailed study about rock oil — and helped launch the petroleum age.
Published in 1860, The Wonder of the Nineteenth Century: Rock Oil in Pennsylvania and Elsewhere described a radical fuel source for the popular lamp fuel kerosene, which had been made from coal for more than a decade.
“Those who have not seen it burn may rest assured its light is no moonshine; but something nearer the clear, strong, brilliant light of day,” Gale declared in his 25-cent pamphlet printed in Erie by Sloan & Griffith Company.
Thomas Gale’s 80-page pamphlet in 1860 marked the beginning of the petroleum age, illuminated with kerosene lamps.
“In other words, rock oil emits a dainty light; the brightest and yet the cheapest in the world; a light fit for Kings and Royalists, and not unsuitable for Republicans and Democrats,” Gale added.
Oil in Rocks
Gale’s descriptions of the value of petroleum helped launch investments in new exploration companies, especially as he noted the commercial qualities of Pennsylvania oil for refining into kerosene, the distilled “coal oil” invented in 1848 by Canadian chemist Abraham Gesner.
Historians regard the 80-page publication as the first book about America’s petroleum industry. The Wonder of the Nineteenth Century: Rock Oil in Pennsylvania and Elsewhere was almost forgotten until 1952, when the Ethyl Corporation of New York republished the work. Only three original copies were known to exist.
“Not by the widest stretch of the imagination could Thomas Gale have realized, when he put down his pen on June 1, 1860, that he had written a book destined to become one of the rarest of all oil books,” proclaimed the Ethyl historian when the company republished Gale’s book.
Ethyl Corporation noted the scarcity of copies of the book had prevented “all but a few historians” from giving the book the attention it deserved.
“Gale wrote his book to satisfy a public desire for more information about petroleum. Newspapers had carried belated accounts of Drake’s discovery well, and the mad scramble for oil that followed, but actually the world knew little about petroleum.”
“The Rock poured…”
The book’s 11 chapters explain practical aspects of the new petroleum industry. Chapters one and two, “What is Rock Oil?” and “Where is the Rock Oil found?” were followed by “Geological Structure of the Oil Region.”
Chapters four through six explained the early technologies (and costs) for pumping the oil, while the next two chapters examine “Uses of Rock Oil.” The final three chapters offered “Sketches of several oil wells,” “History of the Rock Oil Enterprise,” and “Present condition and prospects of Rock Oil interests in different localities.”
A chapter in The Wonder of the Nineteenth Century: Rock Oil in Pennsylvania and Elsewhere features the “geological structure of the oil region,” now part of Oil Creek State Park in northwestern Pennsylvania.
Originally published by Sloan & Griffith of Erie, Pennsylvania, the 1860 cover noted the author as “a resident of Oil Creek” and included a biblical quote, “The Rock poured me out rivers of oil,” from Job, 29:6.
In addition to mysteriously burning gasses and “tar pits,” explorers for millennia have referenced signs of coal, bitumen, and substances very much like petroleum — a word derived from the Latin roots of petra, meaning “rock” and oleum meaning “oil.”
But did Thomas Gayle’s 1860 work produce the first book about oil as Ethyl Corporation historians believed when the company reprinted it in 1952? In fact, there have been many references to natural oil seeps recorded millennia ago (including in the Bible), according to Ray Sorenson. a geologist who has researched the subject (see Earliest Signs of Oil).
Illuminating Petroleum
Several years before the 1859 oil discovery in Pennsylvania, businessman George Bissell hired a prominent Yale chemist to study the potential of oil and its products to convince potential investors (see George Bissell’s Oil Seeps).
“Gentlemen, it appears to me that there is much ground for encouragement in the belief that your company have in their possession a raw material from which, by simple and not expensive processes, they may manufacture very valuable products,” reported Benjamin Silliman Jr. in 1855.
Silliman’s groundbreaking “Report on the Rock Oil, or Petroleum, from Venango Co., Pennsylvania, with Special Reference to its Use for Illumination and Other Purposes,” convinced the petroleum industry’s earliest investors to drill at Titusville. Cable-tool technology developed for brine wells would drill the well.
According to historian Paul H. Giddens in the 1939 classic, The Birth of the Oil Industry, Silliman’s 1855 report, “proved to be a turning-point in the establishment of the petroleum business, for it dispelled many doubts about its value.”
The Pennsylvania Rock Oil Company would evolve into the Seneca Oil Company of New Haven, Connecticut, which became America’s first oil company after Drake completed the first U.S. commercial well drilled seeking oil in 1859.
Rock Oil Products
In addition to providing oil for refining into kerosene lamps (and someday rockets), oilfield discoveries led to many products. Early petroleum products included axle greases, an oilfield paraffin balm, and in Easton, Pennsylvania, Crayola crayons.
Further, oil offered an improved asphalt prior to the first U.S. auto show in November 1900 in New York City’s Madison Square Garden.
Ethyl Corporation was established in 1923 by General Motors and Standard Oil of New Jersey.
Responding to consumer demand for better automobile gasoline, General Motors and Standard Oil of New Jersey established the Ethyl Corporation in 1923. The company marketed its “Brand of Anti-Knock Compound” and initially downplayed the health dangers of tetraethyl lead. Leaded gas would be banned for use in cars in the 1970s.
High-octane leaded aviation fuel proved vital for winning World War II, and the powerful additive still fuels many piston-engine aircraft and racecars.
