Civil War Wiki

Template:Infobox Scientist

Thaddeus Sobieski Coulincourt Lowe (August 20, 1832 - January 16, 1913), also known as Professor T. S. C. Lowe, was an American Civil War aeronaut, scientist and inventor, mostly self-educated in the fields of chemistry, meteorology, and aeronautics. By the late 1850s he was well known for his advanced theories in the meteorological sciences as well as his balloon building. Among his aspirations were plans for a transatlantic flight.

Lowe's scientific endeavors were cut short by the onset of the American Civil War. He recognized his patriotic duty in offering his services as an aeronaut for the purposes of performing aerial reconnaissance on the Confederate troops on behalf of the Union Army. In July 1861 Lowe was appointed Chief Aeronaut of the Union Army Balloon Corps by President Abraham Lincoln. Though his work was generally successful, it was not fully appreciated by all members of the military, and disputes over his operations and pay scale forced him to resign in 1863. Lowe returned to the private sector and continued his scientific exploration of hydrogen gas manufacturing. He invented the water gas process by which large amounts of hydrogen gas could be produced from steam and charcoal. His inventions and patents on this process and ice making machines made him a millionaire.

In 1887 he moved to Los Angeles, California, and eventually built a 24,000 sq. ft. (2,230 m2) home in Pasadena. He opened several ice making plants and founded Citizen's Bank of Los Angeles. Lowe was introduced to David J. Macpherson, a civil engineer, who had drawn up plans for a scenic mountain railroad. In 1891 they incorporated the Pasadena & Mount Wilson Railroad Co. and began the construction of what would become the Mount Lowe Railway into the hills above Altadena. The railway opened on July 4, 1893 and was met with quick interest and success. Lowe continued construction toward Oak Mountain, renamed Mount Lowe, at an exhaustive rate, both physically and financially. By 1899 Lowe had gone into receivership and eventually lost the railway to Jared S. Torrance. Lowe's fortunes had been all but lost, and he lived out his remaining days at his daughter's home in Pasadena where he died at age 81.

Early life[]


Thaddeus Lowe was born August 20, 1832 to Clovis and Alpha Green Lowe in Jefferson Mills, Coos County, New Hampshire. Lowe’s grandfather, Levi Lowe, fought in the Revolutionary War, and his father was a drummer boy in the War of 1812. Both Clovis and Alpha were native New Hampshirites, of pioneer stock and descendants of 17th century Pilgrims. Clovis was a cobbler, but later became a merchant in Jefferson. He dabbled in politics and was even elected to state legislature at one time. His politics and opinion were well respected in the state.[1]


Versions of the life of young Thaddeus vary. He was the second child in a family of five and was named Thaddeus Sobieski Constantine, more than likely after the character Thaddeus Constantine Sobieski in an 1803 novel ‘’Thaddeus of Warsaw’’ by Scottish author Jane Porter.[2] It is confused about his life around the age of ten whether his mother had died and Clovis married Mary Randall, or if Lowe was sent away to another farm during which time his mother died and his father remarried. He apparently did work for another farm owned by the Plaisted’s, but whether or not he lived there is uncertain.[3] Clovis and Mary had seven more children, but there is a timeline confusion that may indicate she already had children when she married Clovis.[4]

What is consistent in the stories of Lowe are accounts of his insatiable appetite for learning. He could not read enough material, and he had questions beyond the answering of his father or teachers. Lowe was also limited in the amount of time he had for school. His farm chores only allowed him the three winter months to attend Common School at Jefferson Hills, two miles away. The school had no books, but like Abraham Lincoln Thad would spend his evenings in front of the fireplace reading books loaned from his teacher’s personal library.[5]

By age fourteen Thad had ventured out on his own first to Portland, Maine, then back to Boston where he joined his older brother Joseph in the shoe [parts] cutting trade. At eighteen Thad became quite ill and returned home. While he was still recuperating when his younger brother invited him to attend a chemistry lecture by one Professor Reginald Dinkelhoff featuring the phenomena of lighter-than-air gases, specifically hydrogen.[6] When the Professor requested a volunteer from the audience, an eager Thaddeus jumped to the fore. Dinkelhoff could see the interest in his eyes and after the show offered to take him on the road with him as an assistant. Lowe did so and after two years upon the professor’s retirement bought out the show using the appellation “Thaddeus Sobieski Counlicourt Lowe, Professor of Chemistry.”[7]

Self-made scientist and aeronaut[]

The lecture circuit business proved lucrative enough for Lowe to seek out the education he so lacked as a child. He tried studying medicine to fulfill his grandmother's wish, but the boredom redirected him to his first interest, aviation with the use of lighter-than-air gases. American balloonists used coke gas to inflate limp silk bags, as opposed to the original French balloons which were cotton weave over rigid frameworks that were stood over fires to collect hot smoke (hot air). By the late 1850s Lowe had become a foremost balloon builder and continued his lucrative business as a showman giving balloon rides to passersby and fairground attendees.


Leontine Augustine Gaschon Lowe

In 1855, at one of his lectures, he was introduced to a pretty Parisian actress, 19-year-old Leonine Augustine Haley Gaston. (Her father was a palace guard of King Louis Phillippe who fled to the U.S. as a political refugee.)[8] A week later, on February 14, 1855, Thaddeus and Leonine wed. Their union would produce ten children, seven girls and three boys. Lowe continued with his scientific endeavors and the dream of owning his own balloon with the wild idea of making a transatlantic flight via the high winds he observed. He pored over the book of John Wise, A System of Aeronautics which had specific instructions for the construction of aerostats, the cutting, the sewing, the leak proofing.[9]

In 1857 Lowe built and piloted his first balloon in tethered flight at a small farm in Hoboken, New Jersey. Thad’s father joined in the balloon making business and had become an accomplished aeronaut himself.[10] In 1858 the Lowes built the larger balloon Enterprise and several others.

Lowe continued with his scientific endeavors and avocation to make a transatlantic flight via the high winds. In 1859 Lowe began the construction of a mammoth balloon to be named the City of New York. Meanwhile he espoused the theory of transatlantic flight to many who had stock market interests in Europe. The recently laid transatlantic cable had failed, and sea travel was undependably slow. He amassed supporters from all corners of the business and scientific communities, in particular one Prof. Joseph Henry of the Smithsonian Institution who wrote:

The Smithsonian Institution has long been aware of the work and theories of Professor Lowe[11] and we have found his statements scientifically sound. It is with great pleasure and satisfaction that we welcome proof of his genius. We shall follow the outcome of his plan with interest.[12]

Transatlantic attempts[]

File:City of NY balloon.jpg

Lowe's mammoth balloon the City of New York, later named Great Western, to be used in a transatlantic flight.

Lowe's latest mammoth balloon, the City of New York, was a massive 103-foot (31.394 m.) diameter balloon with an 11-1/2 ton (10,432.6 kg) lift capacity (on coke gas, 22-1/2 ton [20,411.6 kg.] on hydrogen), which included a 20-foot (6 m.) diameter, 8-man canvas covered gondola and a suspended lifeboat named for his wife Leontine. It was prepared for a test flight to be launched at Reservoir Square in New York on November 1, 1859. Unfortunately the local gas company was not able to deliver a sufficient supply of gas. Within a week Lowe was invited to Philadelphia by Prof. John C. Cresson of the Benjamin Franklin Institute of Sciences, who also happened to be Chairman of the Board of the Point Breeze Gas Works. They promised a sufficient supply of gas. Lowe stored the balloon in Hoboken and waited for spring to do the test flight.[13]

Before the test flight the balloon was renamed the Great Western, on the advice of newspaperman Horace Greeley, to rival the maiden voyage of the steamship Great Eastern in the spring of 1860. Lowe made the flight successfully on June 28, 1860, from Philadelphia to New Jersey, but on his first attempt at a transatlantic launch on September 7, the Great Western was ripped open by a wind. A second attempt on September 29 was halted when the repaired spot on the balloon bulged during inflation. Lowe would need to overhaul the GW and wait for the next late spring.[14]

A second test flight, at the suggestion of Prof. Henry, was made from Cincinnati and was to return him to the eastern seaboard. For this flight he used the smaller balloon Enterprise.[16] His flight took off on the early morning of April 19, 1861, two days after Virginia had seceded from the Union. The flight misdirected him to Unionville, South Carolina where he was put under house arrest as a Yankee spy.[17] Having established his identity as a man of science, he was allowed to return home where he had received word from Secretary of the Treasury Salmon P. Chase to come to Washington with his balloon. The American Civil War permanently ended Lowe's attempt at a transatlantic crossing.

Participation in the Civil War (1861-1863)[]

Chief Aeronaut[]

On the evening of June 11, 1861 Lowe met President Lincoln and offered to perform a demonstration with the Enterprise and a telegraph set from a height some 500 feet (152.4 m.) above the White House. In the telegraph message Lowe asserted:

I have the pleasure of sending you this first dispatch ever telegraphed from an aerial station...[18]

Lowe was competing for the position with three other prominent balloonists, John Wise, John LaMountain, and brothers Ezra Allen and James Allen. Wise and LaMountain were old critics of Lowe, but were not able to obtain the assignment so easily.

Lowe's first outing was at the First Battle of Bull Run, with General Irvin McDowell and the Army of Northeastern Virginia. His performance was impressive, though he had the misfortune of having to land behind enemy lines. Fortunately he was found by members of the 31st New York Volunteers before the enemy could discover him, but after landing, he had twisted his ankle and was not able to walk out with them. They returned to Fort Corcoran to report his position. Eventually his wife Leontine, disguised as an old hag, came to his rescue with a buckboard and canvas covers and was able to extract him and his equipment safely.[19]

Word of his exploits got back to the President, who ordered General Winfield Scott to see to Lowe's formation of a balloon corps, with Lowe as Chief Aeronaut. It was almost four months before Lowe received orders and provisions to construct four (eventually seven) balloons equipped with mobile hydrogen gas generators. At the same time he assembled a band of men whom he would instruct in the methodology of military ballooning. The newly formed Union Army Balloon Corps remained a civilian contract organization, never receiving military commissions, a dangerous position lest any one of the men be captured as spies and summarily executed.[20]

Peninsula Campaign[]

Lowe returned to the Army of the Potomac now under General George McClellan, with his new military balloon the Eagle, though his generators were not ready. He performed ascensions over Yorktown, after which the Confederates retreated toward Richmond. Lowe was given use of a converted coal barge, the George Washington Parke Custis, onto which he loaded two new balloons and two new hydrogen gas generators, with which Lowe performed the first observations over water thereby making the GWP Custis the first ever aircraft carrier. In Lowe’s Official Report to the Secretary Of War, he stated:

Prof. Lowe ascending in the Intrepid to observe the Battle of Fair Oaks

I have the pleasure of reporting the complete success of the first balloon expedition by water ever attempted.

Lowe went on to serve in the Peninsula Campaign of 1862, making observations over Mechanicsville, Virginia, and the ensuing Battle of Seven Pines or Fair Oaks.[21]

The picture to the right depicts Lowe's ascent in the Intrepid over the Battle of Seven Pines, where his observations of the oncoming Confederate Army and the timely manner in which he reported troop movements saved the isolated army of General Samuel P. Heintzelman. Though he had used the hydrogen gas generators (each balloon camp was assigned two generator units), the inflation time was still another hour off. He quickly transferred the gas from the Constitution into the Intrepid by cutting a hole in the bottom of a camp kettle and connecting the balloons at the valve ends. The process took fifteen minutes, a time savings later valued at "a million dollars a minute."[22]

The muddy bogs around Fair Oaks and the Chickahominy River gave rise to many exotic diseases such as typhoid and malaria. Lowe contracted malaria and was put out of service for more than a month.[23] The unsuccessful Army of the Potomac was ordered to retreat to Washington, and Lowe's wagons and mules were commandeered for the withdrawal and eventually returned to the Quartermaster. When Lowe returned to Washington, he was hard pressed to be put back into service. Eventually he was called to Sharpsburg and Fredericksburg, where his services were used.[24]

End of the Balloon Corps[]

The Balloon Corps was reassigned to the Engineers Corps. Lowe had been paid as a colonel ($10 gold per day), but in March 1863, Captain Comstock was put in charge of the newly reassigned air division and cut Lowe's pay to $6 cash ($3 gold). At the same time, a Congressional assessment was being made of the air division and a disparaging third party report, which Lowe refuted in a lengthy response, gave pause to the Union commanders for further use of balloons. In addition, Lowe's appointments of personnel independent of the engineer officers had strained his relations with the military.[25] Lowe tendered his resignation in May 1863 and the Allen brothers took charge of the Balloon Corps, but by August, the Corps had ceased to exist.[26]

Return to the private sector[]

Lowe sought to recuperate from the effects of malaria and the fatigue of war. He and Leontine returned to Jefferson, New Hampshire, where he spent time with his family. He had a month’s return to Washington in the fall of 1863 to complete his war report to the Secretary, then returned home to buy a farm near Valley Forge, where the farming life allowed him to recompose himself.[27]

The advanced techniques of aerial reconnaissance developed by Lowe became influential around the world, Great Britain, France, even Brazil offered him the position of major-general if he were to organize a balloon corps for them. Having had enough of war, he declined the offer, but he did send them a balloon with equipment including portable generators. He consulted with their military experts and recruited his best aeronauts, the Allen brothers, to assist them.[28]

During his Civil War days, Lowe had met a German youth nosing around the army balloon camp. The young man’s name was Count Ferdinand von Zeppelin, who shared his own fascination with aeronautics. General McClellan had put all balloon ride-alongs off limits, so Lowe sent von Zeppelin to Poolesville to visit with his German assistant aeronaut John Steiner who could entertain the lad in his own language. Von Zeppelin returned in the 1870s to interview Lowe on all of his aeronautic techniques. Count von Zeppelin later designed the dirigible aircraft that bore his name.[29]

Lowe made a new home in Norristown, Pennsylvania where he continued with his scientific endeavors with hydrogen gas, improving upon and patenting the water gas process by which high volumes of the volatile fuel could be made from passing steam over hot coal. The industry revolutionized home heating and lighting along the eastern seaboard. He held several patents on ice making machines, including his perfected “Compression Ice Machine” which would revolutionize the cold storage industry. He even discovered that gas burning through a platinum mantle produced a bright illumination (as later found in the Coleman lantern).[30]

He bought an old steamship in which he installed his refrigerating units and began shipping fresh fruit from New York to Galveston, and fresh beef back. This was an historical first where people were able to eat fresh beef that hadn't been packed in preservative salts. His steamship venture failed due to his lack of knowledge about shipping, but the industry was picked up by several other countries.

Lowe also manufactured products that ran on hydrogen gas. With these and his several patents, Lowe amassed a fortune. For his achievements, Lowe received the coveted Elliott Cresson Medal for the Invention Held to be Most Useful to Mankind.[31]

Lowe's gas process[]

In 1873, Lowe developed and patented the water gas process by which large amounts of hydrogen gas could be generated for residential and commercial use in heating and lighting. Unlike the common coal gas, or coke gas which was used in municipal service, this gas provided a more efficient heating fuel. The process used the water gas shift reaction:

CO + H2O → CO2 + H2

The process was discovered by the passing of high-pressure steam over hot coal, the major source of coke gas. Lowe's process improved upon the chimney systems by which the coal could remain superheated thereby maintaining a consistently high supply of the gas. This process created a thermo-chemical reaction of applying hydrogen, in the steam, to carbon monoxide, in the coke gas. The reaction produced carbon dioxide and pure hydrogen which after a process of cooling and "scrubbing," passing through water vapor, left just a pure hydrogen gas.

The process spurred on the industry of gas manufacturing, and gasification plants were established quickly along the Eastern seaboard of the United States. Similar processes, like the Haber Process, led to the manufacture of ammonia (NH3) by the combining of nitrogen, found in air, with high volumes of hydrogen. This spurred on the refrigeration industry which long used ammonia as its refrigerant. Prof. Lowe also held several patents on artificial ice making machines, and was able to run successful businesses in cold storage as well as products which operated on hydrogen gas.

Retirement in Pasadena, California[]

In 1887, Lowe moved to Los Angeles and in 1890 to Pasadena, California, where he built a 24,000 square foot (2200 m2) mansion. He started a water-gas company, founded the Citizens Bank of Los Angeles, established several ice plants, and bought a Pasadena opera house.

Mount Lowe Railway[]

File:Mount Lowe opening day.jpg

Great Incline of the Mount Lowe Railway on opening day, July 4, 1893. The band went up first playing "Nearer My God to Thee."

Early Pasadenans always had a dream of a scenic mountain railroad to the crest of the San Gabriel Mountains. It was one David J. Macpherson, a civil engineer graduate of Cornell University, who had the general plans for just such a railroad. He was introduced to Prof. Lowe with the idea of joining Macpherson’s plans and Lowe’s money together in one venture.

In 1891, Lowe and Macpherson incorporated the Pasadena & Mount Wilson Railroad (later the Mount Lowe Railway[32]). Unable to obtain all the rights of way to Mt. Wilson, the two men redirected their railway toward Oak Mountain via the Echo promontory. The difference between this and any other scenic mountain railway of its kind was that it was an all-electric traction trolley (streetcar), the only one of its kind to ever exist. Oak Mountain was later renamed Mount Lowe, and to make it official, Andrew McNally, the co-founder of the map printing company Rand McNally who had moved to Altadena, had the name Mt. Lowe printed on all his maps.

Lowe opened the first section of the railway on July 4, 1893, from the corner of Lake and Calaveras in Altadena to the Rubio Pavilion in the Rubio Canyon, then transferring to a steep 2,800-foot-long (853.44 m>) funicular to Echo Mountain. At the top there was a 40-room chalet. In 1894, he added an 80-room hotel, the Echo Mountain House, and the observatory. By 1896, the upper division was finished into Grand Canyon at Ye Alpine Tavern. Altogether there were some seven miles (11.265 km) of track. Lowe lost the venture to receivership in 1899, which left him impoverished. The MLR became part of Henry Huntington's recently formed Pacific Electric Railway (also known as "Red Car") in 1902.

The only part of the railway property that remained Lowe's was the observatory on Echo Mountain. It boasted a 16-inch (406.4 mm) reflective telescope from which many astronomical finds were made. It was blown down in a gale in 1928. The railway fell in stages to the Echo Mountain House fire, a kitchen fire on February 4, 1900; a wind-aided brush fire on Echo Mountain in 1905, which wiped out everything except the observatory and the astronomer's cabin; a Rubio Canyon flash flood in 1909 that destroyed the Pavilion; and an electrical fire that razed the Tavern in 1936. The line was abandoned after the Los Angeles deluge of March 1938.

Death and legacy[]

Lowe died at his daughter's Pasadena, California home at age 81 after a few years of failing health. Lowe was buried at Mountain View Cemetery in Altadena, California, Next to him lies his wife Leontine, who died a year later. Also buried near the Lowe monument are his two sons, Leon and Sobieski, and other family members whose names differ due to the married names of the seven daughters. Many of the family members returned to the East Coast. A nearby monument has been separately erected for his son Thaddeus and his wife.[33] Thaddeus Lowe's granddaughter Pancho Lowe Barnes was also an aviation pioneer.

The Mount Lowe Railway was placed on the National Register of Historic Places on January 6, 1993. The mountain itself still bears his name. Lowe is a member of the U.S. Army Military Intelligence Hall of Fame.

Lowe Army Heliport at Fort Rucker, Alabama is named in his honor.

Lowe was a civilian balloonist captured by a mob of town folk and was subsequently being detained as a possible Union spy. Spies are not military people, and are subject to summary execution.
