Densmore brothers advanced oil industry infrastructure — and helped create “QWERTY” typewriter keyboard.
As Northwestern Pennsylvania oil production skyrocketed following the Civil War, railroad oil tank cars fabricated by two brothers improved shipment volumes from oilfields to kerosene refineries. The tank car designed by James and Amos Densmore would not last, but more success followed when Amos invented a new keyboard arrangement for typewriters.
Flatbed railroad cars with two wooden oil tank cars became the latest advancement in oilfield infrastructure after the Densmore brothers patented their design on April 10, 1866.
The inventors from Meadville, Pennsylvania, had developed an “Improved Car for Transporting Petroleum” one year earlier in America’s booming oil regions. The first U.S. oil well had been drilled just seven years earlier along Oil Creek in Titusville.

Using an Atlantic & Great Western Railroad flatcar, the brothers secured two tanks in order to ship oil in bulk. The patent (no. 53,794) described and illustrated the railroad car’s design.
The nature of our invention consists in combining two large, light tanks of iron or wood or other material with the platform of a common railway flat freight-car, making them practically part of the car, so as they carry the desired substance in bulk instead of in barrels, casks, or other vessels or packages, as is now universally done on railway cars.
Development of railroad tank cars came when traditional designs, including the flatcar, hopper, and boxcar, proved inadequate for large amounts of oil — often shipped in 42-gallon barrels.
New designs were born out of necessity, as the fledgling oil industry demanded a better car for the movement of its product, according to American-Rails.com.
“Before the car was developed, railroads used a combination of boxcars, flatcars, and gondolas to haul everything from lumber and coal to crude oil, molasses, and water (by use of barrels),” noted Adam Burns in 2022. “One of the most prolific car types you will find moving within a freight train today is the tank car.”
Prone to leaks and top heavy, Densmore tank cars provided a vital service, if only for a few years before single, horizontal tanks replaced them.
According to transportation historian John White Jr., the Densmore brothers’ oil tank design essentially consisted of a flat car with wooden vats attached. “The Central Pacific is known to have used such specialized cars to transport water, he noted in his 1995 book, The American Railroad Freight Car.
“However, prior to the discovery of oil by Colonel Edward (sic) Drake near Titusville, Pennsylvania, on August 27, 1859, the tank car was virtually non-existent,” added White, a former curator of Transportation at the Smithsonian Institution.
Dual Tank Design
The brothers further described the use of special bolts at the top and bottom of their tanks to act as braces and “to prevent any shock or jar to the tank from the swaying of the car while in motion.”
A Pennsylvania Historical Commission marker on U.S. 8 south of Titusville commemorates the Densmore brothers’ significant contribution to petroleum transportation technology. Dedicated in 2004, the marker notes:
The first functional railway oil tank car was invented and constructed in 1865 by James and Amos Densmore at nearby Miller Farm along Oil Creek. It consisted of two wooden tanks placed on a flat railway car; each tank held 40-45 barrels of oil. A successful test shipment was sent in September 1865 to New York City. By 1866, hundreds of tank cars were in use. The Densmore Tank Car revolutionized the bulk transportation of crude oil to market.
The benefit of such railroad cars to the early petroleum industry’s infrastructure was immense, especially as more Americans eagerly sought oil-refined kerosene for lamps.
Despite design limitations that would prove difficult to overcome, independent producers took advantage of the opportunity to transport large amounts of petroleum. Other transportation methods required teamsters hauling barrels to barges on Oil Creek and the Allegheny River to get to kerosene refineries in Pittsburgh.

As larger refineries were constructed, it was found that it cost $170 less to ship 80 barrels of oil from Titusville to New York in a tank car instead of individual barrels. But the Densmore cars had flaws, notes the Pennsylvania Historical Commission.
They were unstable, top heavy, prone to leaks, and limited in capacity by the eight-foot width of the flatcar. Within a year, oil haulers shifted from the Densmore vertical vats to larger, horizontal riveted iron cylindrical tanks, which also demonstrated greater structural integrity during derailments or collisions.
The same basic cylindrical design for transporting petroleum can be seen as modern railroads load products from corn syrup to chemicals — all in a versatile tank car that got its start in the Pennsylvania oil industry.
The largest tank car ever placed into regular service was Union Tank Car Company’s UTLX 83699, rated at 50,000 gallons in 1963 and used for more than 20 years. A 1965 experimental car built by General American Transportation, the 60,000-gallon “Whale Belly,” GATX 96500, is now on display at the National Museum of Transportation in Saint Louis.
Oil Tanks to Typewriters
Although the Densmore brothers left the oil region by 1867 — their inventiveness was far from over. In 1875, Amos Densmore assisted Christopher Sholes to rearrange the “type writing machine” keyboard so that commonly used letters no longer collided and got stuck. The “QWERTY” arrangement vastly improved Shole’s original 1868 invention.
Amos Densmore helped invent one of the first practical typewriters.
Following his brother’s work with Sholes, inventor of the first practical typewriter, James Densmore’s oilfield financial success helped the brothers establish the Densmore Typewriter Company, which produced its first model in 1891. Few historians have made the oil patch to typewriter keyboard connection — including Densmore biographers.
The Pennsylvania Historical Commission reported that biographies of the Densmore brothers — and their personal papers at the Milwaukee Public Museum — all refer to their innovative typewriters, “but make no mention of their pioneering accomplishment in railroad tank car design.”

Volunteers are key to Oblong museum’s Illinois Basin exhibits and events.
Building a community oil museum is not for the faint of heart. “Money and volunteers, volunteers and money,” are the biggest challenges, according to John Larrabee, board president for the Illinois Oil Field Museum and Resource Center on the outskirts of his hometown of Oblong, Illinois.
The Illinois Oil Field Museum is located in Oblong, Illinois, on Highway 33, southeast of Effingham. First opened in 1961, the museum moved into a new building in 2001. Photos by Kristin L. Wells.
“The first thing you have to have is a goal and the determination to keep at it, no matter what. Don’t give up, whatever happens,” Larrabee explained in a 2004 interview with Kris Wells, American Oil & Gas Historical Society volunteer researcher and contributing editor. (more…)

June 3, 1979 – Bay of Campeche Oil Spill
Drilling in about 150 feet of water, the semi-submersible platform Sedco 135 suffered a blowout 50 miles off Mexico’s Gulf Coast. The state-owned company Pemex well Ixtoc 1 spilled 3.4 million barrels of oil before being brought under control nine months later. Considering the size of the spill, its environmental impact was limited, according to a 1981 report by the Coordinated Program of Ecological Studies in the Bay of Campeche.
Although the extent of environmental alterations from the Ixtoc 1 blowout remain unknown, field surveys of Campeche Sound conducted in 1979–1980 noted, “evaporation, dispersion, photo-oxidation and biodegradation processes played a major role in attenuating the harmful environmental effects of the oil spill.”
June 4, 1872 – Pennsylvania Oilfields bring Petroleum Jelly
A young chemist living in New York City, Robert Chesebrough,
patented “a new and useful product from petroleum,” which he named “Vaseline.” His patent proclaimed the virtues of this purified extract of petroleum distillation residue as a lubricant, hair treatment, and balm for chapped hands.
Robert Chesebrough consumed a spoonful of Vaseline each day and lived to be 96 years old. Photo courtesy Drake Well Museum.
When the 22-year-old chemist visited the new Pennsylvania oilfields in 1865, he had noted that drilling was often confounded by a paraffin-like substance that clogged the wellhead. Drillers used the “rod wax” as a quick first aid for abrasions.
Chesebrough returned to New York City and worked in his laboratory to purify the oil well goop, which he first called “petroleum jelly.” Female customers would discover that mixing lamp black with Vaseline made an impromptu mascara. In 1913, Mabel Williams employed just such a concoction, and it would lead to the founding of a major cosmetic company.

June 4, 1892 – Devastation of Pennsylvania Oil Region
After weeks of thunderstorms in Pennsylvania’s Oil Creek Valley, the Spartansburg dam on Oil Creek burst, sending torrents of water that killed more than 100 people and destroyed homes and businesses in Titusville and Oil City. The disaster was compounded when fires broke out.

“This city during the past twenty-four hours has been visited by one of the most appalling fires and overwhelming floods in the history of this country,” reported the New York Times from Oil City. Oilfield photographer John A. Mather — who lost his studio and 16,000 glass plate negatives — documented the destruction, which preceded the Johnstown Flood by six years.

June 4, 1896 – Henry Ford drives his “Quadricycle”
Driving the first car he ever built, Henry Ford left a workshop behind his home on Bagley Avenue in Detroit, Michigan. He had designed his “Quadricycle” in his spare time while working as an engineer for Edison Illuminating Company. Ford chose the name because his handmade, 500-pound “horseless carriage” ran on four bicycle tires. Inspired by advancements in gasoline-fueled engines, he founded Henry Ford Company in 1903.
June 4, 1921 – Petroleum Seismograph tested
A team of earth scientists tested an experimental seismograph device on a farm three miles north of Oklahoma City and determined it could accurately map subsurface structures. Led by Prof. John C. Karcher and W.P. Haseman, the team from the University of Oklahoma found that seismology could be useful for oil and natural gas exploration and production. Further seismic reflection tests, including one in the Arbuckle formation in August, confirmed their results.
June 6, 1932 – First Federal Gasoline Tax
The federal government taxed gasoline for the first time when the Revenue Act of 1932 added a one-cent per gallon excise tax to U.S. gasoline sales. The first state to tax gasoline had been Oregon, which imposed a one-cent per gallon tax in 1919. Colorado, New Mexico, and other states followed. The federal tax, last raised on October 1, 1993, has remained at 18.4 cents per gallon (24.4 cents per gallon for diesel). About 60 percent of federal gasoline taxes are used for highway and bridge construction.
June 6, 1944 – English Channel Pipelines fuel WWII Victory
As the D-Day invasion began along 50 miles of fortified French coastline in Normandy, logistics for supplying the effort would include two top-secret engineering feats — construction of artificial harbors followed by the laying of pipelines across the English Channel.
Operation PLUTO (Pipe Line Under The Ocean) unspooled flexible steel pipeline across the English Channel, but the channel was deep, the French ports distant.
Code-named “Mulberrys” and using a design similar to modern jack-up offshore rigs, the artificial harbors used barges with retractable pylons to provide platforms to support floating causeways extending to the beaches.
To fuel the Allied advance into Nazi Germany, Operation PLUTO (Pipe Line Under The Ocean) used flexible steel pipelines wound onto giant “conundrums” designed to spool off when towed. Gen. Dwight Eisenhower later acknowledged the vital importance of the oil pipelines.

June 6, 1976 – Oil Billionaire J. Paul Getty dies
With a fortune reaching $6 billion (about $32 billion in 2023), J. Paul Getty died at 83 at his estate near London. Born into his father’s petroleum wealth from the Oil Company of Tulsa, Getty made his first million by age 23 from buying and selling oil leases. “I started in September 1914, to buy leases in the so-called red-beds area of Oklahoma,” Getty told the New York Times. “The surface was red dirt and it was considered impossible there was any oil there. My father and I did not agree and we got many leases for very little money which later turned out to be rich leases.”
Getty, who incorporated Getty Oil in 1942, would leave more than $660 million of his estate to the J. Paul Getty Museum in Los Angeles.
June 9, 1894 – Water Well finds Oil in Corsicana, Texas
A contractor hired by the town of Corsicana to drill a water well on 12th Street found oil instead, launching the Texas petroleum industry seven years before a more famous discovery at Spindletop hundreds of miles to the southeast.
Drilled using cable-tools, Corsicana’s first oil well produced just 2.5 barrels of oil a day from 1,035 feet deep, but nevertheless brought a rush of exploration companies. By 1898, about 300 produced oil in and around the boom town, which became a center for technological innovation. A Corsicana company manufactured the patented rotary rig that drilled the famous 1901 gusher at Spindletop Hill near Beaumont, Texas.
Petroleum transformed Corsicana, Texas, into an oilfield service and industrial center where residents have annually celebrated their oil patch heritage. A colorized postcard depicts Navarro County oil wells, circa 1910.
Despite Corsicana’s discovery well bringing petroleum riches and the drilling boom, city officials paid the contractor only half of the $1,000 fee, citing the agreement for completing a water well. Since 1976 Corsicana has hosted an annual Derrick Days, including a car show and oil history tours. The town also is home to Wolf Brand Chili, established there in 1895 — thanks to the oil boom.
