Nicolaus Otto: the story on HearLore | HearLore
Nicolaus Otto
Nicolaus August Otto was born on the 10th of June 1832 in the small village of Holzhausen an der Haide, Germany, yet he would never complete a formal university education. The youngest of six children, he lost his father in the very year of his birth and spent his early years navigating a life that seemed destined for the mundane trade of a grocery salesman. By 1848, he had moved to the high school in Langenschwalbach, but his academic journey ended abruptly, leaving him to apprentice in a small merchandise company where he sold coffee, tea, rice, and sugar across Western Germany. It was in this world of colonial goods and agricultural products, far removed from the laboratories of Paris or Berlin, that a man who would eventually define the modern age was quietly learning the value of persistence and observation. His early career with companies like IC Alpeter and later Carl Mertens provided him with a practical education in commerce, but his true passion lay in the science and technology that he had studied with such fervor during his brief schooling years. The path from selling sugar to revolutionizing the engine was not a straight line, but a winding road paved with failed experiments and financial struggles that would test his resolve for over a decade.
The Failed Experiment and The Atmospheric Breakthrough
In the late autumn of 1860, Nicolaus Otto and his brother stumbled upon a novel gas engine built by Jean Joseph Etienne Lenoir in Paris, a discovery that would become the catalyst for his life's work. The brothers attempted to build a copy of the Lenoir engine and applied for a patent in January 1861 for a liquid fueled version, but the Prussian Ministry of Commerce rejected their application, leaving them with nothing but a dream and a broken prototype. Otto was aware of the concept of compressed fuel charge and tried to make an engine using this principle in 1861, but it ran for just a few minutes before breaking, a failure that caused his brother to give up on the concept entirely. Facing financial ruin and the collapse of his initial partnership, Otto turned to Cologne Mechanic Michael J. Zons for help between 1862 and 1863, but running low on funds forced him to work for Carl Mertens just to continue his research. It was not until early 1864 that he found the financial backing he needed in Eugen Langen, the son of a sugar industrialist, leading to the formation of NA Otto & Cie on the 31st of March 1864. This partnership created the world's first company focused entirely on the design and production of internal combustion engines, introducing the 1864 Otto & Langen engine, a free piston atmospheric engine that consumed less than half the gas of its predecessors. The engine was a commercial success, producing 634 units a year by 1875, yet it hit a technical dead end as it required significant headroom to operate and produced very little power, forcing Otto to look beyond the atmospheric design that had initially saved his company.
When was Nicolaus Otto born and where did he grow up?
Nicolaus August Otto was born on the 10th of June 1832 in the small village of Holzhausen an der Haide, Germany. He spent his early years in this village before moving to Langenschwalbach for high school in 1848.
What year did Nicolaus Otto and Eugen Langen form their first engine company?
Nicolaus Otto and Eugen Langen formed the company NA Otto & Cie on the 31st of March 1864. This partnership created the world's first company focused entirely on the design and production of internal combustion engines.
When was the four stroke cycle engine introduced by Nicolaus Otto?
The four stroke cycle engine known as the Otto Silent Engine appeared in the autumn of 1876. This engine was the first commercially successful engine to use in-cylinder compression and marked a pivotal moment in engineering history.
Who was the French engineer who held the patent for the four cycle engine concept in 1862?
Beau De Rochas was the French engineer who received a patent for the concept of a four cycle engine in 1862. This patent was issued before Nicolaus Otto and Gottlieb Daimler were aware of it and later allowed Daimler to sell engines without paying royalties.
What year did Nicolaus Otto die and what honors did he receive during his lifetime?
Nicolaus Otto received an Honorary Doctorate from the University of Würzburg in 1882 and won a gold medal at the 1867 World Exhibition in Paris. He died in 1890, leaving behind a legacy that included the standardization of the term Ottomotor by Professor Nagël in 1936.
Otto turned his attention to the four stroke cycle at which he had failed in 1862, a pursuit that would eventually redefine the history of engineering. Largely due to the efforts of Franz Rings and Herman Schumm, who were brought into the company by Gottlieb Daimler, Otto succeeded in making the Four Stroke, Compressed Charge engine, known as the Otto Silent Engine. This engine, which appeared in the autumn of 1876, was the first commercially successful engine to use in-cylinder compression, marking a pivotal moment in the transition from atmospheric engines to the modern internal combustion engine. The Otto engine was designed as a stationary engine, utilizing four distinct strokes: a downward intake stroke where coal-gas and air entered the piston combustion chamber, an upward compression stroke where the piston compressed the mixture, a downward power stroke that ignited the fuel mixture by flame and later electric spark, and an upward exhaust stroke that released exhaust gas from the piston chamber. Unlike the earlier atmospheric engines that relied on vacuum and atmospheric pressure, this new design compressed the fuel-air mixture before ignition, a process that became the standard for all future engines. The term Otto cycle is applied to all compressed charge, four cycle engines, and it is this specific engine, not the earlier atmospheric models, that is recognized by the Association of German Engineers as the true Otto engine. Over 50,000 engines were produced in the 17 years following its introduction, proving that the four stroke cycle was not just a theoretical possibility but a practical reality that would power the industrial world.
The Schism With Daimler and The Patent War
The relationship between Nicolaus Otto and his former manager Gottlieb Daimler ended in a bitter schism that would alter the course of automotive history. When Daimler wanted to build small engines for transportation, Otto showed no interest, leading Daimler to leave and take Wilhelm Maybach with him. Daimler had no desire to pay royalties to Otto's company, Deutz AG, and so hired a lawyer to find a solution to the patent dispute. What the lawyer found was a patent for the concept of a four cycle engine that had been issued to Beau De Rochas, a French engineer, in 1862, a patent that neither Otto nor Daimler had been aware of. This discovery resulted in Otto losing one of his patents and allowed Daimler to sell his engines in Germany without paying royalties, a legal victory that freed the future of the automobile from Otto's control. Rochas never built an engine, and it is likely he could not have done so, yet his patent became the key to unlocking the future of transportation. The only significant engines that preceded the Otto engine were those from Lenoir, which were the first to go into serial production, but the two-stroke atmospheric engines from inventors like Marcus and Barsanti did not compress the fuel charge and were not comparable to Otto's design. The legal battle highlighted the fragility of intellectual property in the early days of engineering innovation, where a forgotten patent from a French engineer could dismantle the empire of a German industrialist.
The Legacy of the Stationary Motor and The Family Line
Otto only sold his engine as a stationary motor, never envisioning the day when his invention would power the first automobiles, a task that would be completed by his former employees Gottlieb Daimler and Karl Benz in 1885. Despite this limitation, his legacy was cemented through numerous honors, including the gold medal won by the 1864 atmospheric engine at the 1867 World Exhibition in Paris and an Honorary Doctorate from the University of Würzburg in 1882. His home has been turned into a museum which is promoted by the local government, preserving the memory of a man who started as a grocery salesman and ended as the father of the internal combustion engine. In 1936, Professor Nagël, head of the Association of German Engineers, decreed that DIN Standard 1940 specify that Ottomotor applies to all engines that draw in a fuel mix, compress it and ignite it by special device, thus replacing such terms as explosion motor, detonation engine, benzine engine, and ignition engine. The company he founded, which changed its name to Langen, Otto, and Roosen in 1869 and later to Deutz Gasmotoren Fabrik in 1872, produced over 2,649 atmospheric engines before discontinuing production in 1884. His personal life was equally significant, as he married Anna Gossi and the couple had seven recorded children, including his son Gustav Otto, who grew up to become an aircraft builder, ensuring that the Otto name would remain synonymous with innovation in the skies as well as on the ground.
