How the name Diesel Engines started
Authored by Martin Leduc, 1999, Updated 2008, 2013
We will start with a brief biography of Rudolph Diesel, born to Theodore and Elise Diesel, in their small Paris apartment, at 38 rue Notre-Dame de Nazareth, on March 18, 1958. Theodore, a leather worker in his late twenties, and making small consumer good, had immigrated from Augsburg, in Bavaria, in 1848. In 1855 he met a Elise, the daughter of a prosperous merchant who was also from Augsburg, they wed shortly after.
Rudolph had an older sister, Louise, born in 1856, as well as a younger sister, Emma, born in 1859. At that time Theodore was having some business success, and moved the family into a new apartment on "rue de la Fontaine au Roi", where he established his small business downstairs. Theodore worked his shop from dawn to dusk, six days a week. He was a strong disciplinarian, but unfortunately, a poor manager of funds.
Rudolph was not allowed to bring friends over, and grew into a shy, but curious youngster, spending much time drawing. His curious nature almost got him killed, when he tinkered with their apartment's gas distribution system. Small lies and "screw ups" were not tolerated by Rudolph's father, standard punishment was swift and hard.

Small lies and "screw ups" were not tolerated by Rudolph's father, standard punishment was swift and hard.
Rudolph's artistic side was matched with excellent academic performance, he spoke three languages: German at home, French at school, and English, which was taught by his mother, a one time governess in London. Rudolph spent his free time at the 'Conservatoire des Art Metiers', a repository for odd and ends of inventions. Rudolph finished elementary school, and was awarded a scholarship for excellence.
France, under Emperor Napoleon III, was sliding into difficult times and a convenient scapegoat of this hardship was the growing confederation known as Germany, and it's dominant Prussian influence. Eventually, France declared war on Prussia, on July 19, 1869. The Diesels considered themselves Bavarian, with more of a French influence than Prussian one. Regardless, when the French army began losing ground, displaced persons quickly engulfed Paris seeking refuge, and the Diesels were ordered out of the country. On September 6, 1869, the Diesels boarded a steamer from Rouen, bound for New Haven, England.
With little comforts in England, the Diesels manage to get by, Louise, the eldest daughter began to work in a private school, while Rudolph was enrolled for school in London. He was most impressed by the British Museum, and the South Kensington Museum's exhibits of science and engineering.
Betty was married to Cristoph Barnickel, a professor at the Augsburg's Royal District Trade School, and they lived in a modest but warm home. They quickly fell in love with Rudolph, after all, he was handsome, modest, and intelligent. 12 year old Rudolph was enrolled in a three year program at Koniglichen Kreis-Gewerbsschule, which offered outlets for all his deepest passion. The chemistry lab, art gallery, machine shop and forge provided fertile ground for a young imaginative mind.
On his fourteen birthday, Rudolph declared that he was to become an engineer! He wrote to his parents in July, 1871, to let them know his intentions to excel in his choice of career. With the war ending six month earlier, Rudolph's family had moved back to Paris, and Theodore was anxious for his son to start earning some money. Soon after finishing industrial school, and placing first in his class, Rudolph returned to Paris. However, tragedy struck the Diesel family, when Rudolph's eldest sister, Louise, dies of heart failure. In light of this development, the Barnickels renew their offer to have Rudolph come back to live with them in Augsburg. Grief-stricken, Theodore accepts their offer.
Back in Bavaria, Rudolph was enrolled in the mechanical engineering program, and as it became the norm, excelled. In 1883, he graduates as the youngest student, with the highest school marks. As a result, he was awarded a scholarship to Munchen Polytechnic, where his interest broaden. In Munchen, Rudolph makes several friendships during this time, and also becomes a German citizen. When Theodore and Elise relocated to Munchen from Paris, they find their towering son, 185 cm, with a prominent scholarship, and a deferment from the required three years of military service.
Rudolph finds his parents had changed, they were a little strange. His father had turn to spirituality soon after his daughter's death, and had set himself up as a faith healer. In the summer of 1879, Rudolph, like many Germans, grew sicker with Typhus. Bedridden and miserable, he completes his final examinations. Typhus had claimed many lives in Germany over that summer, including that of Betty Barnickel.
In January 1880, Rudolph joins the Sulzer Engine Works, in Winterthur, Switzerland, as an apprentice, building refrigeration machines and steam engines. Although "just" an apprentice, a "bleu monteur", he grows more confident in his convictions, and begins his harden belief that there must be a better way - a more fuel efficient machine. At the time, 90% of the fuel for an engine was wasted, a blasphemy to Rudolph, who was raised to loathe waste from his strict father.

Rudolph reads a book by Sadi Carnot - "Reflexion sur la puissance motrisse de feu", published in 1824, and in these writings, he finds the ideals he wanted to achieve. Sadi Carnot was a gifted engineer, specializing in thermodynamics, and he cut right to the heart of the heat engine, giving us the "First Law of Thermodynamics"; "heat and mechanical energy are convertible to each other, but are never created or destroyed, only changed in form". Sadi Carnot also gives us the other two "Laws of Thermodynamics".
As usual, Rudolph excelled in his work, and had made quite an impression with peers and supervisors. He was soon dispatched to Paris, to oversee the building of a refrigeration plant. Despite this jump in status, to white collar, he still earn blue collar wages, a meager existence, void of comforts was the norm for the budding engineer.
1881 was an exhilarating year for apprentice Rudolph. His financial situation changed when Sulzer doubled his salary, and he was also granted his first patent for the production of table ice in glass containers. To cap off the year, Rudolph found a love interest, in the form of a mistress, Martha Flasche, from the United States. She was the Governess of a well to do German family, the Brandes, who approved of Rudolph. Who wouldn't? He was smart, talented, and had a growing salary.

With his first patent secured, Rudolph began to search for a manufacturer to build his conceptual machine. During this search he kindles a friendship with the Augsburg Machine Works, where Heinrich von Buz, and Carl Augustus Reichenbach, once managers, were now owners of the workshop. The Augsburg Machine Works soon began making parts for Diesel's refrigeration machine, which in late 1883 had become a working ice machine. Shortly after this milestone, in November 1883, Rudolph and Martha were married, launching another whirlwind year. The refrigeration machine was a commercial success, and the Diesel began to see some income from it, which was well timed with the birth of their first child, a son, Rudolph Jr.
A year later, in October 1885, Heddy, a baby girl is born to the couple. However, the second child comes into the family, amidst economic troubles. France's sentiment against the German, and even the Swiss is once again troubled, making the "German" made ice machines a hard sell, and Rudolph's income suffers. The burdens of responsibilities, bring back the violent headaches he had suffered from during childhood.
On May 3, 1889, the couple's third child is born, Eugen, arrives into the world amidst strong anti German sentiment. Rudolph is the only German engineer invited at the International Engineering Congress, and presents his paper, "Revue Technique de l'Exposition Universelle". Although he was warmly accepted as a Frenchman, he traded away his refrigeration franchise in France, for the sales rights in Germany, and some money. This would represent a new situation for Rudolph, requiring relocation to Berlin. Rudolph moved his family to Berlin in 1890, to Martha's delight, but he himself had a hard time adjusting to the Prussian military social atmosphere.
A chanced encounter with an old school mate rekindles his competitive spirit, and Rudolph is inspired to work his theories, into an engine design, which he submits for a patent. At first, his submission is declined as being "not original", however, after an appeal, a patent is granted on February 28, 1892. Rudolph now had 15 years of protection, and a pressing need to find a builder for his new engine concept.
The development of Rudolph's ideas at the Augsburg Machine Works result in a steady income for him; but he is anticipating a even better payoff if it the engine works as designed. With this anticipation, he goes on a frenzy of contract signing, and names like Krupp, Sulzer, lines up to sign deals to "be part of the action". The new engine commences testing, and finally, the first run in July 1893. But Rudolph comes to the sudden realization that his design needs much more development work, so much so, that he moves the family into a more modest apartment. The new engine showed promise, but it needed far reaching re-engineering.
On February 17, 1894, the redesigned engine ran for 88 revolutions - one minute; with this news, Maschinefabrik Augsburg's stock rose by 30%, indicative of the tremendous anticipated demands for a more efficient engine. In 1896, Rudolph's rushed to have a prototype running, in order to maintain the patent. The first engine ready for testing was built on December 31, 1896; a much different engine than the one they had started with. In 1897, between deal signing, and brainstorming episodes they succeed, the engine runs; 16.93kW with an efficiency of 16.6%, he is granted the patent.
In 1897, Rudolph was busy, some financial success was finally coming to him. Companies were approaching him for the rights to build his new efficient engine, while at home, Martha and the kids, were moved into a new, luxurious apartment, complete with a staff. Rudolph had reached a form of social success. With that success came a desire to build a mansion, buying property in Munchen for this purpose; Rudolph undertook new hobbies like photography, and was enjoying theatre and opera.

Rudolph Diesel was gifted in many different fields, "including" personal finances, his gift was that no matter how much money came in, more went out.
Rudolph was making many friends, including Graf Ferdinand von Zeppelin and Aldolphus Busch to name few. Adolphus Busch was a German immigrant who had made it big, brewing beer in the United States, he was wealthy and had the means to build Diesel's engine. Upon counsel from his adviser, Busch himself went to Germany, where he proceeded to buy the rights for the new engine from Rudolph Diesel, by nonchalantly writing a check for 1,000,000 marks. It was only the beginning, as newly formed companies lined up for the opportunity to build the new Diesel engine.
In 1898, the inventor's fortieth birthday, he was riding high. A millionaire, on paper, five times over, a wife mingling with the elite social crowd, three beautiful, smart children; along with his personal health and demeanor being radiant. All thanks to his idea of a better, more efficient world, and his hard work and determination to put it together. Indeed, a wonderful time for him.
In order to manage the explosive growth of the Diesel engine, Rudolph establishes a company to manage the licensing, it is called the General Diesel Corporation. Founded on September 17, 1898, and tasked with the further developments and management of the Diesel engine, the corporation buys all of Rudolph's patents for a sum of 3.5 million German marks. Shortly after, Rudolph is diagnosed with nervous exhaustion, and enters a private sanatorium in Munchen.
Not feeling any better, he leaves the Munchen sanatorium, but he is further agonized by the fantastic fortunes beginning to roll in, and the problems associated with it. The violent headaches that had plague him for a long time were becoming more prevalent, and his doctors decide that a "rest castle" in the Alps, might be better for him. In April of 1898, he enters the "rest castle", during his time there, Rudolph invests heavily into an oil development in the Balkans. This investments promptly goes sour, and he loses 300,000 marks, at a time when his "dream" mansion, Maria - Theresia - Strasse 32, was taking shape.
The Maria - Theresia - Strasse 32 mansion was magnificent. It had all the "modern luxuries", as well as kids amenities. Plumbed and wired to the highest standards, marble fireplaces in every room, even the windows were custom made. The decoration was luxurious, painted vaulted ceiling, French furniture, Italian wardrobes etc. All, for a staggering sum of money, pushing the Diesel's financial situation precariously close to disaster. But all was not doom and gloom; in 1900, Rudolph was invited to witness the first flight of the 128 meter Luftshiftf Zeppelin 1 airship, one of the grandest events ever. Additionally, the Diesel engine takes the "Grand Prix", the highest prize, at the 1900 Paris Exposition, an event attended by 50 million people.

1907 was a troublesome year for the Diesels, this, despite their daughter Heddy's marriage to Arnold von Schmidt, an engineer. The marriage was the social event of the year in Munchen, but was marked by the return of headaches, most likely caused by Rudolph's astonishing loss of 3.5 millions marks. Additionally, the patent ran out on the Diesel engine; causing further stress.
In 1904, Rudolph attends a car race in Germany, and comes back excited, with one of his own, a very fast, gas powered Mercedes. With this purchase, he overestimated his ability to drive it, mainly his vision and gouty right foot, so he ends up hiring a driver. Later that year, he decides to travel to the United States. After spending some time in New York City, he traveled to St Louis, to be a guest of Adolphus Busch, who was having a tough time selling the engine in the United States. Rudolph traveled far and wide, and takes in all the sight. Amazingly, the trip rejuvenates him, and as soon as he came back to Germany, he designs and builds a four cylinder "petite" version of his engine. That engine, would later win the 1910 "Grand Prix" in Paris.
Being a pacifist adds further health strains, when war starts brewing in the Balkans. Rudolph takes life a bit slower now, taking time to enjoy simpler things, like hiking. He sells the car to help pay some of his debts, and his friends comment on a "less proud man", that Mr. Diesel had become. The eldest son, Rudolph Jr., leaves school to become a clerk, much to the disappointment of Rudolph senior, but he soon marries, producing a grandson for the Diesels. Eugen, the Diesel's youngest son, had an intense desire to follow in his dad's footstep, and Sulzer in Switzerland, takes him on as a "bleu monteur", like his father 30 years before.
Declaration of war in the Balkans and the mortgage on the new mansion, weight heavy on Rudolph; the future seemed quite bleak. With Martha away to visit her mother in Remscheid, he accepts an invitation to England, to dine with Sir Parsons. Before leaving Munchen, he summons his eldest son for a short visit; Rudolph Jr. would later state that their time together was "bizarre", his father had taken him around the house and showed him the keys for the rooms. Rudolph, on his way to England spends two weeks in Frankfurt, with Heddy, Martha, and his grandchildren. Before leaving Frankfurt, he leaves Martha a leather case, with instruction that it be well looked after, and not opened.
On September 26, 1913, he boards a slow train to Belgium, first class. In Gent, he checks into the Hotel de la Poste, where 31 years earlier he had met his wife Martha. He writes her a loving, but confused letter, which he misaddresses; it would not reach Martha until after a lengthy delay. On September 28, he writes another letter his son, mentioning his headaches and insomnia troubles.
The next afternoon, he boards the steamer Dresden, at Antwerp, with the line's owner, George Carels, and it's chief engineer, Alfred Laukman. That evening, September 29, they have a pleasant dinner with Rudolph, whom they found to be in good spirits. When Rudolph does not meet Mr. Carels and Mr. Laukman for breakfast the following morning, the ship is searched. Rudolph Diesel's cabin was found empty, the bed had not been slept in, and the luggage had not been opened. His coat and hat were found neatly folded under the ship's stern railing. Capt. H Hubert ordered the ship to search, but to no avail, he was reported missing September 30. The inventor's notebook had a small cross under the 29th of September, nothing else.
11 days later, on October 10, the Belgian steamer Coertsen, spots a body in the water and recover personal effects from it, leaving the body at sea. The effects were later identified by Eugen Diesel, in the Dutch port of Vlissingen, as his father's articles. When Martha opened the bag Rudolph had left for her, she found twenty thousand marks, and financial statements showing all bank accounts were empty; it appeared that Rudolph had taken his life.
