Gottlieb Wilhelm Daimler (German pronunciation: [ˈɡɔtliːp ˈdaɪmlɐ]; 17 March 1834 – 6 March 1900[1]) was an engineer, industrial designer and industrialist born in Schorndorf (Kingdom of Württemberg, a federal state of the German Confederation), in what is now Germany. He was a pioneer of internal-combustion engines and automobile development. He invented the high-speed liquid petroleum fueled engine.

Daimler and his lifelong business partner Wilhelm Maybach were two inventors whose goal was to create small, high-speed engines to be mounted in any kind of locomotion device. In 1883 they designed a horizontal cylinder layout compressed charge liquid petroleum engine that fulfilled Daimler's desire for a high speed engine which could be throttled, making it useful in transportation applications. This engine was called Daimler's Dream.[2]

In 1885 they designed a vertical cylinder version of this engine which they subsequently fitted to a two-wheeler, the first internal combustion motorcycle which was named the Petroleum Reitwagen (Riding Car) and, in the next year, to a coach, and a boat. Daimler called this engine the grandfather clock engine (Standuhr) because of its resemblance to a large pendulum clock.

In 1890, they converted their partnership into a stock company Daimler Motoren Gesellschaft (DMG, in English—Daimler Motors Corporation). They sold their first automobile in 1892. Daimler fell ill and took a break from the business. Upon his return he experienced difficulty with the other stockholders that led to his resignation in 1893. This was reversed in 1894. Maybach resigned at the same time, and also returned. In 1900 Daimler died and Wilhelm Maybach quit DMG in 1907.

Early life and education: 1834–1862

Gottlieb Wilhelm Daimler was the son of a baker named Johannes Däumler (Daimler) and his wife Frederika, from the town of Schorndorf near Stuttgart, Württemberg. By the age of 13 (1847), he had completed six years of primary studies in Lateinschule and became interested in engineering.

After completing secondary school in 1848, Daimler had trained as a gunsmith under Master Gunsmith Hermann Raithel. In 1852 he ended the training with the trade examination.[3][4] He graduated in 1852, passing the craft test with a pair of engraved double-barreled pistols.[4] The same year, at eighteen, Daimler decided to take up mechanical engineering, abandoning gunsmithing,[4] and left his hometown.

Signing up at Stuttgart's School for Advanced Training in the Industrial Arts, under the tutelage of Ferdinand von Steinbeis. Daimler was studious, even taking extra Sunday morning classes. In 1853, Daimler, with Steinbeis' assistance, got work at "the factory college", Rollé und Schwilque (R&S) in Grafenstaden, so-called because its manager, Friedrich Messmer, had been an instructor at Karlsruhe Institute of Technology.[4] Daimler performed well, and when Rollé und Schwilque began making railway locomotives in 1856, Daimler, then 22, was named foreman.[4]

Instead of staying, Daimler took two years at Stuttgart's Polytechnic Institute to hone his skills, gaining in-depth grasp of steam locomotives, as well as "a profound conviction" steam was destined to be superseded.[4] He conceived small, cheap, simple engines for light industrial use, possibly inspired by the newly developed gas engines of that era.[4]

In 1861, he resigned from R&S, visiting Paris, then went on to England, working with the country's top engineering firms, becoming knowledgeable with machine tools. He spent from autumn 1861 to summer 1863 in England, then regarded as "the motherland of technology",[5] at Beyer, Peacock and Company of Gorton, Manchester. Beyer was from Saxony.[6] While in London, he visited the 1862 International Exhibition, where one of the exhibits was a steam carriage.[4] These carriages did not evidently inspire him, however, for his wish was to produce machine tools and woodworking machinery.[4]

Career through 1882

Daimler went to work for Maschinenfabrik Daniel Straub,[7] Geislingen an der Steige, where he designed tools, mills, and turbines. In 1863, he joined the Bruderhaus Reutlingen, a Christian Socialist toolmaker, as inspector and later executive.While there, he met Wilhelm Maybach, then a 15-year-old orphan.[4]:482 Thanks to Daimler's organizational skills, the factory managed to show a profit, but he quit in frustration in 1869, joining Maschinenbau Gesellschaft Karlsruhe in July.[4]:482

When in 1872 N.A. Otto and Cie[8] reorganized as Gasmotoren-Fabrik Deutz, management picked Daimler as factory manager, bypassing even Otto, and Daimler joined the company in August, bringing in Maybach as chief designer.[4]:482 While Daimler managed to improve production, the weakness in the Otto's vertical piston design, coupled to Daimler's stubborn insistence on atmospheric engines, led the company to an impasse.[4]:482 Neither Otto nor Daimler would give way, and when Daimler was offered the choice of founding a Deutz branch in St. Petersburg or resigning, he resigned to set up shop in Cannstatt (financed by savings and shares in Deutz),[4]:482-483 where he was shortly joined by Maybach.[4]:482

The Otto four-stroke engine (1876)

In 1872 at age 38, Daimler and Maybach moved to work at the world's largest manufacturer of stationary engines at the time,[9] the Deutz-AG-Gasmotorenfabrik in Cologne. It was half-owned by Nikolaus Otto, who was looking for a new technical director. As directors, both Daimler and Otto focused on gas-engine development while Maybach was chief designer.

In 1876, Otto developed a gaseous fuel, compressed charge four-stroke cycle, (also known as the Otto Cycle) engine after 14 years of effort, a system characterized by four piston strokes (intake, compression, power, and exhaust). Otto intended that his invention would replace the steam engines predominant in those years, even though his engine was still primitive and inefficient.

Otto's engine was patented in 1877, but one of his 25 patents was soon challenged and overturned.[10] Daimler who wanted to make his own engine,feared Otto's patent would prevent it. Daimler hired an attorney who found that a "previous art" patent for a four stroke engine had been issued in Paris in 1862 to Beau De Rochas, a French public works engineer.

Meanwhile, serious personal differences arose between Daimler and Otto, reportedly with Otto being jealous of Daimler, because of his university background and knowledge. Daimler wanted to build small engines that could be applied to transportation but Otto had no interest in this. When Otto excluded Daimler from his engine patents there was great animosity between the two. Daimler was fired in 1880, receiving 112,000 Gold marks in Deutz-AG shares in compensation for the patents of both Daimler and Maybach. Maybach resigned later and followed Daimler.[11]

Independent inventor of small, high speed engines, 1882

Daimler's summer house (Cannstatt)

At Cannstatt, Daimler and the more creative thinking Maybach[4]:482 devised their engine. At Daimler's insistence, it eliminated "the clumsy, complicated slide-valve ignition",[4]:483 in favor of a hot tube system invented by an Englishman named Watson,[12] since electrical systems functioned too slowly.[4]:483

In the summer of 1882 Daimler moved to Cannstatt just outside of Stuttgart at that time, purchasing a cottage in Cannstatt's Taubenheimstrasse, with 75,000 Gold marks from the compensation from Deutz-AG. Maybach followed in September of that year. In the garden, they added a brick extension to the roomy glass-fronted summer house and this became their workshop. Their activities alarmed the neighbors who reported them to the police as suspected counterfeiters. The police obtained a key from the gardener and raided the house in their absence, but found only engines.[13][2]

Daimler and Maybach spent long hours debating how best to fuel Otto's four-stroke design, and turned to a commonly available petroleum fraction. The main distillates of petroleum at the time were lubricating oil, kerosene (burned as lamp fuel), and ligroin (Petroleum Naptha), which up to then was used mainly as a cleaner and was sold in pharmacies. "Leichtbenzin, wie es damals üblich und in der Apotheke zu bekommen war", blickt Oldtimer-Experte Michael Plag zurück. "Das ist ein verbrennungsfähiger Kraftstoff - Hexan N." [English]"Mineral spirits were common and easy to get at the pharmacy", recalls classic car expert Michael Plag. "This is a combustion-efficient fuel - hexane N."[14]

The Dream engine 1883

In late 1883, Daimler and Maybach patented the first of their engines fueled by ligroin. This engine was patented on December 16, 1883. It achieved Daimler's goal of being small and running fast enough to be useful at 750 rpm.[13] Improved designs in the next four years brought that up to 900 rpm.[13] Daimler had three engines built to this design early in 1884, and a flywheel was included in one of the engines. This design was smaller and lighter than engines by other inventors of the time. Daimler relied on hot tube ignition, until 1897, when he adopted the electrical ignition designed by Bosch.[13]

The engine with the flywheel included was built into a light vehicle, called the Reitwagen, the first vehicle powered by an internal combustion engine.[13]

It took considerable effort and experimentation, but eventually, the duo perfected a .5 hp (0.37 kW; 0.51 PS) vertical single, which was fitted in the Reitwagen, a purpose-built two-wheeler chassis with two spring-loaded stabilizerss.[4]:483

Features of the 1885 Engine included:

  • a single horizontal cylinder of 264 cc (16 cu in)[15] (58×100 mm, 2.28×3.94 in)[15]
  • air cooling
  • large cast iron flywheel
  • surface carburetor[16]
  • hot tube ignition system (patent 28022)
  • cam operated exhaust valves, allowing high speed operation
  • 0.5 hp (370 W)[15]
  • 600 rpm running speed, beating previous engines, which typically ran at about 120 to 180 rpm[17]
  • weight of around 50 kg (110 lb)[15]
  • height of 76 cm (30 in)[15]

In 1885, they created a carburetor which mixed gasoline with air allowing its use as fuel. In the same year Daimler and Maybach assembled a larger version of their engine, still relatively compact, but now with a vertical cylinder of 100 cc displacement and an output of 1 hp at 600 rpm (patent DRP-28-022: "non-cooled, heat insulated engine with unregulated hot-tube ignition"). It was baptized the Standuhr ("grandfather clock"), because Daimler thought it resembled an old pendulum clock.

In November 1885, Daimler installed a smaller version of this engine in a wooden two wheeler frame with two outrigger wheels, creating the first internal combustion motorcycle (Patent 36-423impff & Sohn "Vehicle with gas or petroleum drive machine"). It was named the Reitwagen (riding car). Maybach rode it for three kilometers (two miles) alongside the river Neckar, from Cannstatt to Untertürkheim, reaching 12 kilometres per hour (7 mph).

First automobile 1886

Independently of each other, Carl Benz and Gottlieb Daimler each produced an automobile in 1886, both in Germany, about 60 miles apart.[18]

About sixty miles away in Mannheim, Carl Benz built the first true automobile using an integral design for a motorized vehicle with one of his own engines. He was granted a patent for his motorwagen on 29 January 1886.

When this proved the engine capable of driving a vehicle, Daimler devised a 1.1 hp (0.82 kW; 1.1 PS) single and ordered a Wimpff und Soehne four-seater phaeton to house it.[4]:483 Daimler's engine was installed by Maschinenfabrik Esslingen and drove the rear wheels through a dual-ratio belt drive.[4]:483

On 8 March 1886, Daimler and Maybach secretly brought an American Model coach made by Wilhelm Wimpff and Sohn into the house, telling the neighbors it was a birthday gift for Mrs. Daimler. Maybach supervised the installation of a larger 1.1 hp[15] 462 cc (28 cu in)[15] (70×120 mm, 2.76×4.72 in)[15] version of the Grandfather Clock engine into this stagecoach and it became the first four-wheeled vehicle to reach 16 kilometres per hour (10 mph). The engine power was transmitted by a set of belts. As with the motorcycle, it was tested on the road to Untertürkheim where nowadays the Mercedes-Benz Arena, formerly called the Gottlieb-Daimler-Stadion, is situated.

Driven by Daimler's desire to use the engine as many ways as possible,[15] Daimler and Maybach used the engine in other types of transport including:

  • on water (1886), by mounting it in a 4.5 m (15 ft) long boat and achieving a speed of 6 knots (11 km/h; 6.9 mph). The boat was called Neckar after the river where it was tested. (patent DRP 39-367). This was the first motorboat and boat engines soon would become Daimler's main product for several years. The first customers expressed fear the petrol engine could explode, so Daimler hid the engine with a ceramic cover and told them it was "oil-electrical".
  • street-cars and trolleys.
  • in the air in Daimler's balloon, usually regarded as the first airship, where it replaced a hand-operated engine designed by Dr. Friedrich Hermann Wölfert of Leipzig. With the new engine, Daimler successfully flew over Seelberg on 10 August 1888.

They sold their first foreign licenses for engines in 1887 and Maybach went as their representative to the 1889 Paris Exposition to show their achievements.

Engine sales increased, mostly for use in boats, and in June 1887, Daimler bought another property at Seelberg hill, Cannstatt. It was located some distance from the town on Ludwigstraße 67 because Cannstatt's mayor did not approve of the workshop. Built at a cost 30,200 goldmarks, the new premises had room for 23 employees. Daimler managed the commercial issues while Maybach ran the engine design department.

In 1889, Daimler and Maybach built the Stahlradwagen, their first automobile that did not involve adapting a horse-drawn carriage with their engine, but which was somewhat influenced by bicycle designs. There was no production in Germany, but it was licensed to be built in France and presented to the public in Paris in October 1889 by both engineers. The same year, Daimler's wife, Emma Kunz, died.

With demand for engines growing, for uses in everything from motorboats to railcars,[4]:483 Maybach and Daimler expanded. With funding from gunpowder maker Max Duttenhofer, industrialist, and banker Kilian von Steiner, and munitions manufactuer de:Wilhelm Lorenz, Daimler Motoren Gesellschaft was founded 28 November 1890, with Maybach as chief designer. Its purpose was the construction of small, high-speed engines for use on land, water, and air transport. The three uses were expressed by Daimler in a sketch that became the basis for a logo with a three-pointed star.

Pact with the devil

From 1882 until 1890 Daimler had resisted making his company into an incorporation or stock company. He had seen what happened to too many engineers who had pioneered a capital invention as he had. Many of them were forced out of their own companies by stock holders who "knew better" about how to run the company that they had just purchased than the man who created it. This is a very common occurrence in the business world. It happened to Henry Ford, Ransom E. Oldsmobile, Carl Benz, August Horch (Audi), Gottlieb Daimler and many others.

Many German historians consider this Daimler's "pact with the devil".[19]

Daimler hated having to incorporate his company. Unable to obtain majority control, he sold out and then resigned.[20] DMG expanded, but it changed. The newcomers, not believing in automobile production, ordered the creation of additional stationary engine building capacity, and considered merging DMG with Otto's Deutz-AG.

Daimler and Maybach preferred plans to produce automobiles and reacted against Duttenhofer and Lorenz. Maybach was denied a seat on the board and on 11 February 1891, he left the business. He continued his design work as a freelance in Cannstatt from his own house, with Daimler's support, moving to the closed Hermann Hotel in the autumn of 1892. He used its ballroom and winter garden as workshops, employing twelve workers and five apprentices.

The new company developed the high-speed inline-two Phönix, for which Maybach invented a spray carburettor.[4]:483 This was fitted in a singularly ugly car,[4]:483 which entered production in 1895 after a cessation of hostilities between Daimler, Maybach, and the DMG board.[4]:483

First automobile sold (1892)

In 1892, DMG finally sold its first automobile. Gottlieb Daimler, aged 58, had heart problems and suffered a collapse in the winter of 1892–1893. His doctor prescribed a trip to Florence, where he met Lina Hartmann, a widow 22 years his junior who was the owner of the hotel where he was staying. They married on 8 July 1893, honeymooning in Chicago during its World Fair.[21]

Returning from the 1893 World's Fair in Chicago with his new wife, Daimler had vowed to purchase enough shares of DMG to regain control. This effort failed. Daimler sold all his shares and patents and resigned from the Company. Maybach had left earlier.[21]

The disputes with Lorenz continued. Daimler attempted to buy 102 extra shares to get a majority holding, but was forced out of his post as technical director. The corporation was 400,000 Gold marks in debt. The other directors threatened to declare bankruptcy if Daimler didn't sell them all his shares and all his personal patent rights from the previous thirty years. Daimler accepted the offer, receiving 66,666 Gold Marks, and resigned in 1893.

In 1894 at the Hermann Hotel, Maybach together with Daimler and his son Paul designed a third engine called the "Phoenix" and had DMG make it. It featured:

  • four cylinders cast in one block arranged vertically and parallel
  • camshaft operated exhaust valves
  • a spray nozzle carburetor, patented by Maybach in 1893
  • an improved belt drive system

This is probably the same internal-combustion engine referred to by the American author and historian Henry Brooks Adams, who describes the "Daimler motor" and its great speed from his visit to the 1900 Paris Exposition in his autobiography.[22]

Race results in the return of Daimler 1894

Daimler and Maybach continued to work together. They built a four-cylinder engine with Maybach' spray nozzle carburetor. It was in the first organized automobile race, the "Paris to Rouen" and defeated all the entries from DMG. This caused DMG stock to fall. Frederick Simms, a major investor from Britain insisted that Daimler be brought back into the company.[23] British investor industrialist Frederick Simms was so embarrassed that Daimler and Maybach's car had beaten the DMG entries that he made it a condition of his 350,000 mark purchase of a Phoenix engine license, which would stabilize the corporation's finances, that Daimler, now aged sixty, should return to DMG. Gottlieb Daimler received 200,000 goldmarks in shares, plus a 100,000 bonus. Simms received the right to use the name "Daimler" as his brand name for the engines. In 1895, the year DMG assembled its 1,000th engine, Maybach returned as chief engineer, receiving 30,000 shares.

During this period, they agreed to licenses to build Daimler engines around the world, which included:

Daimler died in 1900, and in 1907 Maybach resigned from DMG.

The Founding of Daimler-Benz

Daimler had developed the first liquid petroleum vehicle in 1885 and Carl Benz had developed the first purpose built automobile using a 2 cycle engine of his own design a few months later. Daimler never met Carl Benz during the period of invention. In 1896 Daimler (DMG) sued Benz & Cie for violating his 1883 patent on hot tube ignition. Daimler won and Benz had to pay royalties to DMG. Daimler did not meet Carl Benz while they were in court in Mannheim. Later at the founding of the Central European Motor Car Association Daimler and Benz still did not speak to ether other.

Years after Daimler died, the two companies did cooperate in many ways. After many years of cooperation On June 28, 1926 representatives of Daimler-Motoren-Gesellschaft (DMG) and Benz & Cie signed the agreement for the merger of the two oldest automobile manufacturers in the world. The resulting new company was named Daimler-Benz.[29]


Gottlieb Daimler was accepted into the Automotive Hall of Fame in 1978. Between 1993 and July 2008 Daimler had a stadium named after him in Stuttgart, Germany. The Mercedes-Benz Arena was the venue for six matches in the 2006 FIFA World Cup in Germany.

Gottlieb Daimler's motto was Das Beste oder nichts ("The best or nothing at all"; "Nothing but the best").[30] Mercedes-Benz adopted this motto as their slogan in 2010.
