New Mexico wildcatter discovers high-grade uranium after decades of drilling dry holes.
Stella Dysart spent almost 30 years unsuccessfully searching for oil in New Mexico. In 1955, a radioactive uranium sample from one of her “dusters” made her a very wealthy woman.
In the end, it was the uranium — not petroleum — that made Dysart her fortune. The sometimes desperate promoter of oil drilling ventures in New Mexico for more than 30 years, she once served time for fraud. But in 1955, Mrs. Dysart learned she owned the world’s richest deposit of high-grade uranium ore.
LIFE magazine featured Stella Dysart in 1955 after she made a fortune from finding uranium but failed in her oil ventures.
Born in 1878 in Slater, Missouri, Dysart moved to New Mexico, where she got into the petroleum and real estate business in 1923. She ultimately acquired a reported 150,000 acres in the remote Ambrosia Lake area 100 miles west of Albuquerque, on the southern edge of the oil-rich San Juan Basin.
Dysart established the New Mexico Oil Properties Association and the Dysart Oil Company. The ventures and other investment schemes would leave her broke, according to John Masters and Paul Grescoe in their 2002 book, Secret Riches: Adventures of an Unreformed Oilman.
The authors describe Dysart as a woman who drilled dry holes, peddled worthless parcels of land to thousands of dirt-poor investors, and went to jail for one of her crooked deals.
Dysart subdivided her properties and subdivided again — selling one-eighth acre leases and oil royalties as small as one-six thousandth to investors. She drilled nothing but dry holes for years. Then it got worse.
Before finding uranium, Stella Dysart served 15 months for the unauthorized selling of New Mexico oil leases. In 1941, she promoted her Dysart No. 1 Federal well, above, which was never completed.
A 1937 Workmen’s Compensation Act judgment against Dysart’s New Mexico Oil Properties Association bankrupted the company, compelling sale of its equipment, “sold as it now lies on the ground near Ambrosia Lake.”
Two years later, it got worse again. Dysart and five Dysart Oil Company co-defendants were charged with 60 counts of conspiracy, grand theft, and violation of the Corporate Securities Act in 1939. All were convicted, and all did time. Dysart served 15 months in the county jail before being released on probation in March 1941.
Uranium Riches
By 1952, 74-year-old Dysart was $25,000 in debt when she met uranium prospector Louis Lothman, a young Texan just two years out of college with a geology degree.
When Lothman examined cuttings from a Dysart dry hole in McKinley County in 1955, he got impressive Geiger counter readings. The drilling of several more test wells confirmed the results. Dysart owned the world’s richest deposit of high-grade uranium ore.

The uranium discovery launched an intensive exploration effort that led to the development of multi-million-ton deposits in the Ambrosia Lake area, according to William L. Chenoweth of the U.S. Energy Research and Development Administration.
“The San Juan Basin of northwest New Mexico has been the source of more uranium production than any other area in the United States,” he noted in a New Mexico Geological Survey 1977 report, “Uranium in the San Juan Basin.”
Dysart was 78 years old when the December 10, 1955, LIFE magazine featured her picture, captioned: “Wealthy landowner, Mrs. Stella Dysart, stands before abandoned oil rig which she set up on her property in a long vain search for oil. Now uranium is being mined there and Mrs. Dysart, swathed in mink, gets a plump royalty.”
Praised for her success, and memories of fraudulent petroleum deals long forgotten, Dysart died in 1966 in Albuquerque at age 88. As Secret Riches author John Masters explained, “there must be a little more to her story, but as someone said of Truth — ‘it lies hidden in a crooked well.’”

The gas that would not burn — and the professor who in 1905 extracted helium from a natural gas well.
Drilling for natural gas in May 1903, an exploratory well drilled by Gas, Oil and Developing Company found natural gas beneath William Greenwell’s farm near Dexter, Kansas. The discovery came as the company drilled into a geologic formation that produced “a howling gasser” that would not burn.

“I look forward to hearing anything your knowledgeable AOGHS community can tell me about my rather mysterious AC-ME Pocket Calculator.”
David Rance of Sassenheim, Netherlands, has collected a lot of slide rules — the analog calculating devices that became obsolete when handheld electronic calculators gained widespread use in the early 1970s. Rance and others like him have preserved “pocket calculator” collections around the world. (more…)

President Woodrow Wilson in 1914 opened a maritime project to support petrochemicals.
The Houston Ship Channel, the “port that built a city,” opened for ocean-going vessels on November 10, 1914, making Texas home to a world-class commercial port. President Woodrow Wilson saluted the occasion from his desk in the White House by pushing an ivory button wired to a cannon in Houston.

The National Anthem played from a barge in the center of the Turning Basin as Sue Campbell, daughter of Houston Mayor Ben Campbell, sprinkled white roses into the water, according to a Port of Houston historian.

“I christen thee Port of Houston; hither the boats of all nations may come and receive a hearty welcome,” Campbell proclaimed.
The bayou had been used to ship goods to the Gulf of Mexico as early as the 1830s. The American Society of Civil Engineers (ASCE) described the original waterway — known as Buffalo Bayou — as “swampy, marshy and overgrown with dense vegetation.”
“Steamboats and shallow-draft vessels were the only boats able to navigate the complicated channel,” noted ASCE, adding that in 1909, Harris County citizens formed a navigation district (an autonomous governmental body for supervising the port) and issued bonds to fund half the cost of dredging the channel.

According to the Port of Houston Authority of Harris County, in 1937 the steamship Laura traveled from Galveston Bay up Buffalo Bayou to what is now Houston.
The steamship Laura’s trip — in water no deeper than six feet — proved the bayou was navigable by “sizable vessels” and established a commercial link between Houston and ports around the world

“With the discovery of oil at Spindletop in 1901 and crops such as rice beginning to rival the dominant export crop of cotton, Houston’s ship channel needed the capacity to handle newer and larger vessels,” reported the Port Authority, administrator of the channel.
Harris County voters in January 1910 overwhelmingly approved dredging their ship channel to a depth of 25 feet for $1.25 million. The U.S. Congress provided matching funds. As work began in 1912, similar giant maritime projects included construction of the Panama Canal and the Gulf Intracoastal Waterway.

By 1930, eight refineries were operating along the deep water channel, ASCE notes. The area eventually supported massive petrochemical complexes along the shoreline of processing facilities and oil refineries, including ExxonMobil’s Baytown Refinery.
Under continuous development since its original construction, the Houston Ship Channel has been extended to reach 52 miles with a depth of 45 feet and a width of up to 530 feet. It travels from the Gulf through Galveston Bay and up the San Jacinto River, ending four miles east of downtown Houston.
Although the dredging vessel Texas first signaled by whistle the channel’s completion on September 7, 1914, the official opening date has remained when Sue Campbell sprinkled her white roses and President Wilson remotely fired his cannon.
With refineries and expanded liquefied terminals for exporting natural gas (LNG), the Texas waterway has grown into one of the largest petrochemical facilities in the world.

Early autos shared unpaved roads with horses and wagons.
The first U.S. auto show opened in New York City’s Madison Square Garden in 1900, just five years after Charles Duryea claimed the first American patent for a gasoline-powered automobile. Gas proved to be the least popular source of engine power.
