Famous German Inventions: From Benz's Car to Fischer's Wall Plug

German engineering culture is known for more than just cars. Germany is associated with Karl Benz’s gasoline-powered automobile, Philipp Reis’s early electric telephone, Heinrich Hertz’s experiments with electromagnetic waves, Arthur Fischer’s plastic wall plug, Chlorodont toothpaste, and Litfass advertising columns. Below is an overview of inventions that clearly show how laboratory experiments, craftsmanship, and entrepreneurship changed everyday life.

Karl Benz and the gasoline-powered automobile

Karl Benz was born on November 25, 1844, in Muhlburg, which is now part of Karlsruhe. After his father’s death, the family lived modestly, but his mother supported her son’s education. Benz graduated from the technical school in Karlsruhe, the future Karlsruher Institut fuer Technologie, and began his career as a design engineer.

In the 1870s, Benz worked on engines and dreamed of a vehicle that could move on its own, without horses or rails. Bertha Benz played an important role: she supported her husband financially and organizationally and later effectively proved the practical value of his machine.

The world’s first gasoline-powered automobile was invented by the German engineer Karl Benz.

Why the Patent-Motorwagen became important

In 1883, Benz founded the company Benz & Cie. Rheinische Gasmotorenfabrik in Mannheim. His goal differed from many early experiments: he designed not just an engine placed on a cart, but a complete vehicle with a frame, motor, steering, and ignition as one integrated system.

On January 29, 1886, Benz filed patent application DRP 37435 for a “vehicle with a gas engine.” The Benz Patent-Motorwagen is usually called the first practical gasoline-powered automobile created as an independent means of transport.

At first, the public treated the machine cautiously. The turning point was Bertha Benz’s trip in 1888 from Mannheim to Pforzheim. The route of about 100 kilometers showed that a car could be used outside a showroom: along the way she had to buy ligroin at a pharmacy, repair the brakes, and solve everyday technical problems.

By the end of the 19th century, Benz & Cie. was producing different car models. In 1926, the company merged with Daimler-Motoren-Gesellschaft, after which Daimler-Benz AG and the Mercedes-Benz brand appeared.

Philipp Reis and the early telephone

Johann Philipp Reis was a schoolteacher of physics and mathematics. In 1861, in Frankfurt am Main, he demonstrated a device that could transmit sounds electrically. The device entered history as the Reis telephone.

Reis did not achieve the same commercial success as Alexander Graham Bell, whose telephone patent became a turning point for the communications industry. So it is more accurate to say not “Reis invented the modern telephone,” but “Reis created one of the first working devices for the electrical transmission of sound.”

Why contemporaries did not appreciate the device

The phrase often associated with Reis’s demonstrations was “The horse does not eat cucumber salad.” It was chosen deliberately: a meaningless sentence is harder to guess from context, so it shows better whether the sound was really transmitted.

The scientific community treated the experiment cautiously. Reis was not a university professor, and the very idea of transmitting speech over wires seemed too bold to many people. He made several copies of the device and shared the drawings, but he died of tuberculosis in 1874 without seeing the era of mass telephony.

The invention of the ancestor of all telephones: Philipp Reis’s device, the first apparatus to transmit sound over a distance.

Heinrich Hertz and electromagnetic waves

Heinrich Hertz was born in Hamburg in 1857. He studied engineering, physics, and mathematics, worked with Hermann von Helmholtz, and became one of the most important experimental scientists of the 19th century.

In 1886-1888, Hertz experimentally confirmed the existence of electromagnetic waves predicted by James Clerk Maxwell’s theory. He showed that electrical oscillations can spread through space as waves and can be reflected and refracted. For future radio communication, this was fundamental proof.

From a laboratory experiment to radio

Hertz himself did not build a business plan around wireless communication and was reserved about the practical application of his experiments. But his work became the scientific foundation for radio, television, mobile communication, and many technologies that use electromagnetic waves.

During his experiments, Hertz also observed a phenomenon connected with the photoelectric effect. The later explanation of the photoelectric effect became one of the works for which Albert Einstein received the Nobel Prize.

The biography of the German physicist Heinrich Hertz is notable for the discovery of electromagnetic waves.

In his honor, the unit of frequency was named the hertz (Hz). One hertz means one oscillation per second.

Arthur Fischer: the wall plug and the synchronized photo flash

Arthur Fischer was born on December 31, 1919, in Tumlingen. He became one of the most productive German inventors of the 20th century: his name is associated with fasteners, photography, toys, and many technical solutions.

Photo flash

After the war, Fischer turned to his own developments. According to a widely repeated version, the idea for a synchronized photo flash came to him after taking pictures of his newborn daughter: magnesium flashes produced bright light, but they were inconvenient and posed a fire hazard. The point of Fischer’s solution was to synchronize the flash with the camera shutter so that the bright pulse appeared exactly at the moment of the shot.

Plastic wall plug

Fischer’s best-known invention was the plastic expansion wall plug. Early wall plugs were made from lead, wood, or metal, but such materials had limitations: weight, sensitivity to moisture, and weak fixation in some walls.

Fischer used plastic and a shape that expanded when a screw was driven in. Cuts and side elements helped the wall plug stay in the hole. This simple idea is exactly what turned the fastener into a mass-market household item.

Ottomar Heinsius von Mayenburg and Chlorodont toothpaste

At the beginning of the 20th century, regular oral hygiene was not yet as routine as it is today. Tooth powders had existed for a long time, but they were inconvenient to use, and the idea of toothpaste in a tube was only starting to gain popularity.

Ottomar Heinsius von Mayenburg, who worked in a German pharmacy in Dresden, began experimenting with toothpaste in 1907. His product was called “Chlorodont” and became one of the best-known German brands in this category.

Why Chlorodont became notable

Mayenburg promoted not only a specific product but also the habit of brushing teeth regularly. Toothpaste in a tube was more convenient than powder, easier to dose, and better suited to everyday use. Advertising, packaging, and mass production helped make dental care part of everyday culture.

Some advertising claims from the early 20th century should now be treated as historical context rather than as medical statements. Modern preventive recommendations depend on the toothpaste composition and the advice of dentists.

Ernst Litfass and advertising columns

Ernst Theodor Amandus Litfass was born in Berlin in 1816 into a family connected with the printing trade. In the middle of the 19th century, Berlin, like other European cities, suffered from posters being pasted chaotically on walls, fences, and trees.

Litfass offered city authorities a simple way to bring order: special cylindrical columns for notices and posters. In Germany, such structures are called Litfasssaeule, the “Litfass column.”

How Litfass columns differed from ordinary advertising

The first Berlin columns appeared in 1855, earlier than the Parisian Morris columns, which are often mistakenly considered the first. The idea quickly proved useful: advertisers got legal places for posters, and the city got a neater visual environment.

During the wars of the 19th century, the columns displayed not only theater posters but also official announcements. In this way, the advertising structure also became a city information medium.

What these inventions have in common

These stories are different, but they share a common logic: German inventors often turned a technical detail into a system suitable for mass use. Benz made the automobile practical transportation, Hertz provided the physical proof for future communication, Fischer improved household fasteners, Mayenburg connected a product with a new habit, and Litfass solved an urban problem through the design of city infrastructure.

For a reader interested in Germany, such inventions matter not only as a list of dates. They show how scientific schools, craft production, patents, and entrepreneurship shaped German technical culture.
