End of Oil Exchanges

Standard Oil curbed the excitement of unruly speculators trading oil and pipeline certificates.

 

In a sign of the growing power of John D. Rockefeller at the end of the 19th century, Standard Oil Company brought a decisive end to Pennsylvania’s highly speculative  — and often confusing — trading markets at oil exchanges.

On January 23, 1895, the Standard Oil Company’s purchasing agency in Oil City, Pennsylvania, notified independent oil producers it would only buy their oil at a price “as high as the markets of the world will justify” and not necessarily “the price bid on the oil exchange for certificate oil.” The action would bring an end to the “paper oil” markets of brokers and buyers.

Ironing with Gasoline

“Self-Heating Sad Irons” patented in 1903 used gasoline to make ironing easier.

 

On ironing day long before electricity, a row of sad irons could be found in the kitchen where the family’s cast-iron cook stove kept them hot. Three or four of these heavy “sadirons” — from the old English word meaning “solid” — cycled between the stove and a nearby ironing board.

With each sad iron weighing five to nine pounds, smoothing clothes led to an exhausting ironing routine. In 1872, Mary Florence Potts from Ottumwa, Iowa, patented a sad iron design with two pointed ends and a quick-change detachable walnut handle.

The 19-year-old housewife’s invention offered relief from blistered palms and was instantly popular nationwide. Thirty years later, a Civil War veteran brought another innovation to ironing.

Gasoline-fueled Sad Iron

John C. Lake, who served in the 16th Ohio Volunteer Infantry Regiment during the Civil War, patented (No. 725,261) a gasoline-fueled “Self-Heating Sad Iron” in April 1903.

Lake’s invention made the family fortune and brought prosperity to Big Prairie, Ohio, where he established the Monitor Sad Iron Company on the Pennsylvania Railroad line. The manufacturing company in Amish country would make petroleum-fueled sad irons for the next 50 years.

The 61-year-old inventor earlier had shared three woodworking tool patents with his father Abraham, but none led to production. Lake’s new gasoline-fired sad iron would bring easier ironing to households without electrical service, which in 1903 meant most of America.

As advertised, “Monitor Self-Heating Sad Irons” did not need the kitchen stove, maintained a steady temperature, and turned on and off with a knob. Two tablespoons of alcohol started the process and charged the reservoir delivery system.

“Save Half the Time, Half the Labor, and All the Worry of Laundry Day,” the ads proclaimed as consumers warmly welcomed the gasoline-fueled sad irons, which sold for $3.50 each.

Monitor Sad Iron Company expanded by licensing an army of sales agents. As the factory in Big Prairie grew, by 1920 the company could proclaim 850,000 in cumulative sales. In the 1930s, Monitor added a new brand (Royal) as Lake’s son Bertus received three patents for improvements.

Geologist Iron Man

Antique iron collector Prof. Kevin McCartney knows a lot about Monitor Sad Iron Company and its early competitors like Jubilee and Ideal. A professor of Geology at the University of Maine at Presque Isle, he also serves as director of the Northern Maine Museum of Science.

Since 2013, McCartney has posted more than 50 YouTube videos, “to educate and entertain the avid collector, antique shop owner, pickers and novices alike. Each video is a mini-lesson on a different topic about irons.”

In his Kevin Talks Irons number 54, “Firing up the 1903 Monitor gasoline iron,” he described how consumers preferred Monitor’s gasoline appliance — made with just three durable assemblies — because it was “simple, utilitarian, and economical.”

The Monitor Sad Iron Company’s patented self-heating design became “most common of the early gasoline irons.” Formerly a byproduct of kerosene refining, gasoline also had begun its transformation from “white gas” into an automobile fuel before Anti-Knock Ethyl and other additives added color.

Coleman Lamp Company entered the gasoline-fueled iron business in the 1920s. Based in Wichita, Kansas, Coleman began producing a self-heating iron while securing additional patents in 1940.

Products from Monitor, Coleman, Royal and others competed in catalog offerings and advertisements, especially for potential customers in rural, unelectrified regions. The self-heating appliances burned the basic white gas (naphtha). Coleman later branded and sold the fuel in one-gallon containers as Coleman Fuel.

Coleman Company quit manufacturing gasoline-fueled sad irons after World War II, and the Monitor Sad Iron factory closed in 1954 as electricity relegated most such artifacts to museums and antique shops.

When Mary Florence Potts originally patented her innovative sad iron (today commonly spelled sadiron), she used her name instead of Mrs. Joseph Potts, according to a 2021 “Out of the Attic” article by Julie Martineau of Des Moines County Historical Society (DMCHS).

New London School Explosion

Horrific East Texas oilfield tragedy of 1937.

 

At 3:17 p.m. on March 18, 1937, with just minutes left in the school day and more than 500 students and teachers inside the building, a massive explosion leveled most of what had been the wealthiest rural school in the nation.

Hundreds died at New London High School in Rusk County after odorless natural gas leaked into the basement and ignited. The sound of the explosion was heard four miles away. Parents, many of them roughnecks from the East Texas oilfield, rushed to the school.

Despite immediate rescue efforts, 298 died, most from grades 5 to 11 (dozens more later died of injuries). After an investigation, the cause of the school explosion was found to be an electric wood-shop sander that sparked the residue gas vapors (also called casinghead gas) that had pooled beneath and in the walls of the school.

Wyatt Earp’s California Oil Wells

Famed lawman and wife gambled on Kern County oil leases.

 

Old West lawman and gambler Wyatt Earp and his wife Josie in 1920 bet oil could be found on a barren piece of California scrub land. A century later, his Kern County lease still paid royalties.

Ushered into modest retirement by notoriety, Mr. and Mrs. Wyatt Earp were known — if not successful — entrepreneurs with abundant experience running saloons, gambling houses, bordellos (Wichita, Kansas, 1874), real estate, and finally western mining ventures.

Quietly retired in California, the couple alternately lived in suburban Los Angeles or tended to gold and copper mining holdings at their “Happy Days” camp in the Whipple Mountains near Vidal. Josephine “Josie” Marcus Earp had been by Wyatt’s side since his famous 1881 O.K. Corral gunfight in Tombstone, Arizona.

Also in California, Josie’s younger sister, Henrietta Marcus, had married into wealth and thrived in Oakland society while Josie and Wyatt roamed the West. “Hattie” Lehnhardt had the genteel life sister Josie always wanted but never had. When Hattie’s husband Emil died by suicide in 1912, the widow inherited a $225,000 estate.

Money had always been an issue between the Earps, according to John Gilchriese, amateur historian and longtime collector of Earp memorabilia.

Josie liked to remind Wyatt he had once employed a struggling gold miner — Edward Doheny — as a faro lookout (armed bouncer) in a Tombstone saloon. Doheny later drilled for oil and discovered the giant Los Angeles oilfield in the early 1880s.

The Los Angeles field launched southern California’s petroleum industry, creating many unlikely oil millionaires — including local piano teacher Emma Summers, whose astute business sense earned her the title “Oil Queen of California.”

In addition to oilman Doheny, Earp socialized with prominent Californians like George Randolph Hearst (father of San Francisco Examiner publisher William), whom he knew from mining days in Tombstone. But the former lawman’s ride into the California oil patch began in 1920 when he gambled on an abandoned placer claim.

Kern County Lease

In 1901, a petroleum exploration venture had drilled a wildcat well about five miles north of Bakersfield in Kern County. The attempt generated brief excitement, but nothing ultimately came of it. When Shasta Oil Company drilled into bankruptcy after three dry holes, the land returned to its former reputation — worthless except for sheep grazing.

Earp decided to bet on black gold where Shasta Oil had failed. But first, California required that he post a “Notice of Intent to File Prospectors Permit.” He sent his wife to make the application. But on her way to pay the fees with paperwork in hand, Josie was diverted by gaming tables. She lost all the money, infuriating Wyatt and delaying his oil exploration venture.

Earp later secured the Kern County lease claim he sought, mostly with money from his sister-in-law, Hattie Lehnhardt, 

Wyatt Earp CA oil Lease map.

Wyatt Earp purchased a mineral lease in Kern County, PLSS (Public Land Survey System) Section 14, Township 28 South, Range 27 East.

The San Francisco Examiner declared, “Old Property Believed Worthless for Years West of Kern Field Relocated by Old-Timers.” The newspaper — describing Earp as the “pioneer mining man of Tombstone” — reported that the old Shasta Oil Company parcel had been newly assessed.

“Indications are that a great lake of oil lies beneath the surface in this territory,” the article proclaimed. “Should this prove to be the case, the locators of the old Shasta property have stumbled on to some very valuable holdings.”

Meanwhile, competition among big players like Standard Oil of California and Getty Oil energized the California petroleum market. By July 1924, Getty Oil had won the competition and began to drill on the Earp lease.

Support the American Oil & Gas Historical Society

On February 25, 1926, a well on the lease was completed with production of 150 barrels of oil a day. During 1926, nine of the wells produced a total of almost 153,000 barrels of oil. “Getty has been getting some nice production in the Kern River field ever since operations were started,” reported the Los Angeles Times.

Rarely exceeding 300 barrels of oil a day, the Getty wells were not as large as other recent California discoveries (see Signal Hill Oil Boom), but they produced oil from less than 2,000 feet deep, keeping production costs low. Royalty checks would begin arriving in the mail.

With the Oil and Gas Journal reporting “Kern River Front” oil selling for 75 cents per barrel, the Earps received $3,174 from 12 active wells producing 282,116 barrels of oil from February 1927 to January 1928, according to the 2019 book A Wyatt Earp Anthology: Long May His Story Be Told.

At age 78, Wyatt Earp’s oil gamble finally paid off — but there was a catch.

No Royalty Riches

Because of her gambling, Josie Earp had become so notoriously incapable of managing money that Earp gave control of the lease to her younger sister, Hattie Lehnhardt. At the same time, he directed that his wife “receive at all times a reasonable portion of any and all benefits, rights and interests.”

From February 1928 to January 1929, production from the dozen Earp wells declined to 91,770 barrels, “grossing $68,827 with Josie’s royalties amounting to a mere $1,032,” noted the anthology’s editors.

With that, Earp’s venture in the Kern County petroleum business became a footnote to his legend, already well into the making. By the time of his death on January 13, 1929, his gamble on oil, still known as the Lehnhardt Lease, had paid Josie a total of almost $6,000.

The disappointing results would prompt Josie to write, “I was in hopes they would bring in a two or three hundred barrel well. But I must be satisfied as it could have been a duster, too.”

When benefactor Hattie Lehnhardt died in 1936, her children (and some litigation) put an end to the 20 percent of the 7.5 percent of the Getty Oil royalties formerly paid to their widowed aunt Josephine. Eight years later, when Josephine died, she left a total estate of $175, including a $50 radio and a $25 trunk.

The Lehnhardt lease in Kern County would remain active. From January 2018 to December 2022, improved secondary recovery in the Lehnhardt oil properties of the California Resources Production Corporation produced 440,560 barrels of oil, according to records at ShaleXP.

Kern County Museums

Beginning in 1941, the Kern County Museum in Bakersfield has educated visitors with petroleum exhibits on a 16-acre site just north of downtown. The museum offers “Black Gold: The Oil Experience,” a permanent $4 million science, technology, and history exhibition.

The museum also preserves a large collection of historic photographs.

In Taft, the West Kern Oil Museum also has images from the 1920s showing more than 7,000 wooden derricks covering 21 miles in southwestern Kern County, according to Executive Director Arianna Mace. 

Run almost entirely by volunteers — and celebrating its 50th anniversary in 2023 — the oil museum collects, preserves, and exhibits equipment telling the story of the Midway-Sunset field, which, by 1915, produced half of the oil in California. The state led the nation in oil production at the time.

Since 1946, Taft residents have annually celebrated “Oildorado.” The community in 2010 dedicated a 30-foot Oil Worker Monument with a derrick and bronze sculptures of Kern County petroleum pioneers.

Both Kern County museums played credited roles in the 2008 Academy Award-winning movie “There Will Be Blood.” Production staff visited each museum while researching realistic California wooden derricks and oil production machinery. During a visit to the West Kern Oil Museum, the film’s production designer purchased copies of authentic 1914 cable-tool derrick blueprints.

Manuel “Lone Wolf” Gonzaullas, Texas Ranger

The Ranger who tamed oil and gas boom towns during the Great Depression. “Crime may expect no quarter.”

 

During much of the 1920s, a Texas Ranger became known for strictly enforcing the law in oilfield communities. By 1930, the discovery year of the largest oilfield in the lower 48 states, he was known as “El Lobo Solo” — the lone wolf — the Ranger who brought law and order to East Texas boom towns.

Manuel Trazazas Gonzaullas was born in 1891 in Cádiz, Spain, to a Spanish father and Canadian mother who were naturalized U.S. citizens. At age 15 he witnessed the murder of his only two brothers and the wounding of his parents when bandits raided their home. Fourteen years later, Gonzaullas joined the Texas Rangers.

Manuel "Lone Wolf" Gonzaullas, Texas Ranger: portrait of the lawman.

“Give Texas more Rangers of the caliber of ‘Lone Wolf’ Gonzaullas and the crime wave we are going through will not be of long duration,” reported the Dallas Morning News in 1934.

“He was a soft-spoken man and his trigger finger was slightly bent,” independent producer Watson W. Wise characterized him during a 1985 interview in Tyler, Texas. “He always told me it was geared to that .45 of his.” (more…)

Puente Oil at Los Angeles Harbor

Picturing California petroleum history in a family album.

 

Preserving a family’s photographs from Los Angeles Harbor brought insights into California’s maritime and petroleum heritage — including the 1920s story of Puente Oil Company.

Among many others, a photograph of men working at an oil facility at San Pedro Harbor of Los Angeles preserves the petroleum heritage of the Raynor family. Seeking to share the legacy of her father career at the Los Angeles Harbor Authority, Valerie Raynor contacted the American Oil & Gas Historical Society in 2017 (see AOGHS Oil Families). 

The search for a permanent home for Paul Thome’s collection did not take long. His daughter, a longtime resident in the Los Angeles area, decided to donate them to the Los Angeles Maritime Museum after talking with Mary Frances, the museum’s director.
