Karl Friedrich Michael Vaillant was born in Mühlburg, now a borough of Karlsruhe, Baden, which is part of modern Germany, to Josephine Vaillant and a locomotive driver, Johann George Benz, whom she married a few months later.According to German law, the child acquired the Name “Benz” by legal marriage of his parents Benz and Vaillant. When he was two years old, his father was killed in a railway accident, and his name was changed to Karl Friedrich Benz in remembrance of his father. Despite living in near poverty, his mother strove to give him a good education. Benz attended the local Grammar School in Karlsruhe and was a prodigious student.
In 1853, at the age of nine he started at the scientifically oriented Lyceum.
Benz had originally focused his studies on locksmithing, but eventually followed his father’s steps toward locomotive engineering. On September 30, 1860, at age fifteen, he passed the entrance exam for mechanical engineering at the University of Karlsruhe, which he subsequently attended. Benz was graduated July 9, 1864 at nineteen. During these years, while riding his bicycle, he started to envision concepts for a vehicle that would eventually become the horseless carriage.
Following his formal education, Benz had seven years of professional training in several companies, but did not fit well in any of them. He then moved to Mannheim towork as a draftsman and designer in a scales factory. In 1868 he went to Pforzheim to work for a bridge building company Gebrüder Benckiser Eisenwerke und Maschinenfabrik. Finally, he went to Vienna for a short period to work at an iron construction company. In 1871, at the age of twenty-seven, Karl Benz joined August Ritter in launching the Iron Foundry and Mechanical Workshop in Mannheim, later renamed Factory for Machines for Sheet-metal Working.
Despite the business misfortunes, Karl Benz led in the development of new engines in the early factory he and his wife owned. To get more revenues, in 1878 he began to work on new patents. First, he concentrated all his efforts on creating a reliable petrol two-stroke engine. Benz finished his two-stroke engine on December 31, 1878, New Year’s Eve, and was granted a patent for it in 1879.
Karl Benz showed his real genius, however, through his successive inventions registered while designing what would become the production standard for his two-stroke engine. Benz soon patented the speed regulation system, the ignition using sparks with battery, the spark plug, the carburetor, the clutch, the gear shift, and the water radiator.
Benz’s lifelong hobby brought him to a bicycle repair shop in Mannheim owned by Max Rose and Friedrich Wilhelm Eßlinger. In 1883, the three founded a new company producing industrial machines: Benz & Company Rheinische Gasmotoren-Fabrik, usually referred to as, Benz & Cie. Quickly growing to twenty-five employees, it soon began to produce static gas engines as well. The success of the company gave Benz the opportunity to indulge in his old passion of designing a horseless carriage. Based on his experience with, and fondness for, bicycles, he used similar technology when he created an automobile.
It featured wire wheels (unlike carriages’ wooden ones) with a four-stroke engine of his own design between the rear wheels, with a very advanced coil ignition and evaporative cooling rather than a radiator. Power was transmitted by means of two roller chains to the rear axle. Karl Benz finished his creation in 1885 and named it the Benz Patent Motorwagen.
It was the first automobile entirely designed as such to generate its own power, not simply a motorized-stage coach or horse carriage, which is why Karl Benz was granted his patent and is regarded as its inventor. The Motorwagen was patented on January 29, 1886 as DRP-37435: “automobile fueled by gas”. Benz began to sell the vehicle (advertising it as the Benz Patent Motorwagen) in the late summer of 1888, making it the first commercially available automobile in history. After Bertha Benz made her famous trip driving one of the vehicles a great distance and suggested to her husband the addition of another gear; the vehicle was then equipped with gear.
During the last years of the nineteenth century, Benz was the largest automobile company in the world with 572 units produced in 1899. In 1895, Benz designed the first truck in history, with some of the units later modified by the first motor bus company: the Netphener, becoming the first motor buses in history. In 1896, Karl Benz was granted a patent for his design of the first flat engine. It had horizontally opposed pistons, a design in which the corresponding pistons reach top dead centre simultaneously, thus balancing each other with respect to momentum.
On April 4, 1929, Karl Benz died at home in Ladenburg at the age of eighty-four from a bronchial inflammation. The Benz home now has been designated as historic and is used as a scientific meeting facility for a nonprofit foundation, the Gottlieb Daimler and Karl Benz Foundation, that honors both Bertha and Karl Benz for their roles in the history of automobiles.
