Numerous patents for pioneering inventions
Stuttgart, May 22, 2002
Reutlingen in the summer of 1865: the 31-year-old engineer Gottlieb
Daimler is the workshop manager within the engineering works of the
"Bruderhaus", a social institute with adjoining production
facilities built and run by orphans and the homeless for orphans and
the homeless. Out of the young adults who work there, his attention
is caught by a 19-year-old with a sparkling talent for drawing, who
produces an endless stream of design drafts in the factory's own design
offices: designs for paper manufacturing machines, for scales, as
well as for all manner of farming implements. His name is Wilhelm
Maybach.
The two soon form a close bond: the younger Maybach, who was tragically
orphaned when aged only ten, sees an inspirational father figure in
Daimler, a much travelled man who is well versed in the ways of the
world. The older man, on the other hand, immediately recognises Maybach's
potential as a designer. This marks the beginning of a partnership
that will continue for many years.
But Gottlieb Daimler has career ambitions and is considering leaving.
At the end of 1868, he switches from the "Bruderhaus" to
the Maschinenbau-Gesellschaft in Karlsruhe, whose manufacturing portfolio
includes heavy-duty locomotives. Maybach follows him barely six months
later, joining the company as a technical draughtsman. The two spend
countless nights discussing the development of motor engines
motors for pumps, for machining wood or for punching metal panels.
Both are quite clear in their minds that only powerful, durable drive
units would be capable of speeding up industrial processes in order
to rationalise manufacturing.
In 1872, clients from Deutz near Cologne pay a visit to the factory:
the Gasmotorenfabrik there is looking for a technical director. Gottlieb
Daimler seizes the opportunity, both for himself and for Wilhelm Maybach,
and the two move north to the Rhineland. One of the factory's founders
in Deutz is Nikolaus August Otto, whose atmospheric gas engines had
already drawn attention and who went on to invent the four-stroke
engine in 1876. Maybach is charged with optimising the design of this
engine and with preparing it for series production. The result is
a success: the smooth-running "Otto silent" engine is patented
in Germany on August 4, 1877 with the patent number DRP 532.
Garden shed is turned into development laboratory
Although business could not be better, Otto and Daimler make no secret
of their animosity towards one another, and in 1882 Daimler returns
to the South of Germany. Now aged 48, he purchases a large property
in Cannstatt, which is at the time still an autonomous municipality
close to Stuttgart. As well as the main house, there is also a small,
glass-fronted outhouse which offers plenty of light. It is here that
Daimler goes about first setting up a workshop and then appoints his
like-minded companion of many years, Wilhelm Maybach, as the "chief
designer" of the two-man operation. The objective is clear: to
give the four-stroke engine a bit of a helping hand. Petrol, previously
used mainly for removing stains and available exclusively from the
pharmacist, was to fuel the engine. Both work tirelessly day and night.
All their hard work soon pays off: the major breakthrough comes at
the end of 1883, when they succeed in running a four-stroke engine
with a single horizontal cylinder which is far lighter than the engines
produced in Deutz. In 1884, it reaches the 600 rpm mark, a sensational
speed at that time. The high speed is made possible by the curve groove
mechanism invented by Daimler and Maybach themselves, as well as the
hot-tube ignition process, which was another revolutionary step forward.
In his patent application no. 28022 dated December 16, 1883, Gottlieb
Daimler had described the ignition mechanism as "a metal ignition
cap, the inside of which has a constantly open connection to the combustion
chamber", which then ignites the fuel/air mixture.
This is followed just a short time later in 1884 by the first fast-running
engine with a vertical cylinder, which can be run on petrol thanks
to Maybach's float carburettor. The first test engine of this type
goes down in engineering history as the "Grandfather Clock",
a reference to its striking arrangement with the vertical cylinder.
It generates about one horsepower at a speed of 600 rpm, and is so
compact that its inventors claim it can be fitted in boats, fire tenders,
sledges and carriages.
Test drive on the "Petroleum Riding Carriage"
Daimler and Maybach focus initially on two-wheeled motorised transport:
in 1885, a "grandfather clock" with a displacement of 0.264
litres powers what was actually the first ever motorcycle, consisting
of a "gas or petroleum engine positioned underneath the seat
and between the two vehicle axles of a single-track chassis"
to quote the original patent application lodged on August 29, 1885.
Just three months later, Maybach tests out the so-called "Reitwagen"
or "riding carriage" on the three-kilometre route from Cannstatt
to Unterturkheim, without experiencing any problems and reaching a
top speed of twelve km/h.
The work has long since outgrown the garden shed when in 1887 Gottlieb
Daimler buys a large plot of land on the Seelberg in Cannstatt where
he begins to set up workshops for producing engines. The working partnership
is a successful one: Maybach develops, Daimler builds up the contacts
and sells the engines. The firm employs 23 highly skilled workers
on the Seelberg. It is here that Maybach develops a water-cooled,
two-cylinder engine as the successor to the legendary "grandfather
clock" which is unable to provide enough power for its planned
use in four-wheeled vehicles.
The new V-type engine is demonstrated at the 1889 World Exhibition
in Paris running in a vehicle designed by Maybach known simply as
the "wire-wheel car". The response is tremendous. Licenses
for engine manufacture are soon being granted in France where a rapidly
increasing number of drive units are being fitted in cars and with
great success; a clear sign for Daimler and Maybach to start to turn
their attention more to car manufacturing.
In order to drum up the capital for the necessary expansion, the
Daimler-Motoren-Gesellschaft (DMG) is founded on November 28, 1890
with the support of a number of industrialists. It soon becomes obvious,
however, that Gottlieb Daimler would not be able to work together
in the long term with the financiers, bureaucrats and sceptics within
the company management, who, to make matters worse, are far more interested
in manufacturing stationary engines than cars.
Groundbreaking inventions made in the heart of the former spa
hotel
As his influence begins to wane, Daimler finds a way out: after leaving
as a result of contractual problems back in 1891, Wilhelm Maybach
is commissioned to carry on his research under the strictest secrecy
in the dance hall of the former Hotel Hermann in Cannstatt. He is
given free rein and is assisted by twelve workers and five apprentices.
It is not long before the brilliant designer unveils the Phoenix engine,
consisting of two vertical cylinders cast together to form a single
block. This engine marks a further engineering milestone with its
spray-nozzle carburettor, the basis for all modern carburettor technology.
Finally, Maybach designs the celebrated four-seater "belt-driven
car", of which 150 are built by 1899.
Things have in the meantime taken a turn for the worse at the Daimler-Motoren-Gesellschaft
since Maybach's departure. Loans need to be taken which cannot be
repaid and bankruptcy is looming. On October 10, 1894 Gottlieb Daimler
leaves his company with a compensation payment of 66,666 marks. He
is back just one year later though, accompanied by Wilhelm Maybach
as technical director. This had been at the insistence of the Englishman
Frederick Richard Simms who bought the licensing rights to the Phoenix
engine for the princely sum of 350,000 marks, at the same time saving
DMG from ruin.
It is time for a serious rethink. The rest of the company management
also starts to realise how much potential cars hold for the future.
The annual report for 1895 clearly bear's the mark of the firm's founder
Gottlieb Daimler, asserting that, "All available resources are
to be channelled into developing motor vehicle manufacturing, as following
the recent successes ... demand is growing constantly."
Premiere for new lightweight four-cylinder engine
Maybach's inventions stimulate an economic upturn in the years that
follow; after developing the tubular radiator to improve engine cooling
and increase power output in 1897, Maybach goes on to design the Phoenix
car featuring a front-mounted drive unit and then produces a new generation
of lightweight four-cylinder engines, which use the magneto make-and-break
ignition system invented by Robert Bosch to generate peak outputs
of up to 23 hp. The 4-speed geared transmission and a 23-hp racing
car to crown the model range also draw much acclaim. The result is
a two-fold increase in DMG's revenues between 1898 and 1900 to 1.6
million marks.
When Gottlieb Daimler passes away on March 6, 1900 at the age of
almost 66, it marks the end of a great era. Throughout their 35 fruitful
years of working together, Daimler and Maybach had constantly proved
themselves to be the perfect match: Daimler, the fountain of ideas
and great visionary; Maybach, the design genius who breathed life
into those visions and gave them form.
Stimuli for the first true car
Maybach retains his post as chief designer at DMG, whose fate over
the course of the next few months is influenced by two names more
than any other: those of Emil Jellinek and Mercedes.
Jellinek, who had established a successful business selling Daimler
models on the Cote dAzur in Southern France, tells the Stuttgart
car-makers in no uncertain terms what displeases him about the cars:
"too high up," he says, "and the short wheelbase makes
them too wobbly." Maybach listens and then goes back to
the drawing board. The new design, which bears the name of Jellinek's
daughter, Mercedes, and which finally marks the end of the age of
carriages, is viewed by automotive historians as the "first true
car". From this time on, the French regard Maybach as the "roi
des constructeurs", the king of design.
The joy is short-lived however. Maybach is feeling the effects of
the gruelling work, soul-sapping burdens such as the death of Gottlieb
Daimler and the ongoing frictions within DMG; in the autumn of 1903,
aged 57, he is taken seriously ill and sent to convalesce in Northern
Italy and Switzerland. His influence in the corporate hierarchy begins
to gradually crumble, and on April 1, 1907 he leaves DMG for a final
time following persistent conflict and sets out together with his
son Karl to build a new future for themselves in the airship industry,
which is just starting to take shape.
On December 29,1929, Wilhelm Maybach dies at the age of 83. He is
buried in Cannstatt, very near to the grave of his companion over
those many years, Gottlieb Daimler.
The garden shed in Bad Cannstatt
A workshop full of memories
Original "grandfather clock", "riding carriage"
and Daimler motorised carriage
Following Gottlieb Daimler's purchase in 1882 of a large property
in Cannstatt, still an autonomous municipality close to Stuttgart
at that time, he and Wilhelm Maybach set up their workshop in the
garden shed that made up part of the property. Both worked tirelessly
day and night to redevelop the fast-running four-stroke engine, and
devise numerous inventions, such as the hot-tube ignition system.
Today, following careful restoration, the old garden shed has been
converted into the "Gottlieb-Daimler Memorial" located in
Cannstatt's spa park, and showcases the birthplace of the age of motorisation,
which is as simple as it is fascinating. Visitors can also see the
modest resources that the two men had at their disposal at the time
as they worked inside a building measuring less than 100 square metres.
Chronological tables describe how Daimler's and Maybach's careers
evolved together. The transition from the age of horse-drawn carriages
to the car is documented by exhibits including a "riding carriage"
dating from 1885, as well as a working model of the Daimler motorised
carriage from 1886, equipped with the vertical "grandfather clock"
engine. The former workshop also has a model of the first petrol-powered
engine with hot-tube ignition and an original "grandfather clock"
engine on show.
The sturdy wooden workbench is a magnificent piece of nostalgia in
itself: spanners, tyre levers and files are in mint condition, while
hand-operated drilling tools and a whetstone are examples of what
was considered the technological state of the art at the time. Visitors
will also find a fully equipped forge, complete with smith's hearth
and anvil, where Daimler and Maybach laboured away to shape every
single work-piece, lever and axle they needed for their pioneering
designs.
Although the garden shed gradually slipped into disuse as a workshop
following the move to the new factory on the Seelberg in Cannstatt
in 1887, its enormous significance for motoring history has been preserved
for all to see.

Chronology
Gottlieb Daimler and Wilhelm Maybach -
Visions, inventions and patents
1865
Gottlieb Daimler and Wilhelm Maybach first cross paths at the "Bruderhaus"
in Reutlingen where Daimler manages the workshops in the engineering
works there. The 19-year-old Wilhelm Maybach from Heilbronn, whose
parents had been tragically killed, works in the design office there.
His extraordinary talent for drawing soon catches Daimler's attention.
1868
Daimler joins the board of the Maschinenbaugesellschaft in Karlsruhe
and calls up Maybach barely six months later to work as a technical
draughtsman.
1872
Daimler takes over a post as technical director of the Gasmotorenfabrik
in Deutz, founded by Nikolaus Otto and Eugen Langen. A short time
later, aged 27, Maybach is appointed head of the design office in
Deutz, during which time he prepares the four-stroke engine invented
by Otto himself in 1876 for series production.
1878
Wilhelm Maybach marries Bertha Habermaas, a friend of Emma Daimler,
the wife of Gottlieb Daimler since 1867.
1882
After persistent personal conflicts and disagreements on design matters
with Nikolaus Otto, Gottlieb Daimler leaves his post at the Gasmotorenfabrik
in Deutz. It is in Cannstatt near Stuttgart that he buys a generously
sized property with a villa, and has the garden shed that is part
of the property converted to a workshop. Wilhelm Maybach follows shortly
afterwards. The aim of both men: to develop a fast-running four-stroke
engine that is suitable for universal use.
1883
Daimler's and Maybach's work in the garden shed leads to the development
of hot-tube ignition and many other improvements to the internal combustion
engine. The patents for these inventions lay the legal cornerstone
for their subsequent commercial success.
1884
The test engine reaches the 600 rpm mark for the first time. This
is followed in the same year by the "grandfather clock",
a petrol-powered engine with a vertical single cylinder intended for
use in boats, fire tenders and other equipment.
1885
Testing carried out with the "riding carriage" the precursor
of the modern-day motorbike. It is powered by the "grandfather
clock" engine.
1886
The engine is fitted in a carriage for the first time, which becomes
known as the "motorised carriage". Daimler and Maybach have
just started to open up the tremendous potential of individual, motorised
transportation.
1887
Operations are moved to a larger production facility in Cannstatt,
where mostly engines are manufactured, as well as test vehicles.
1889
Daimler's "wire-wheel car", a lightweight four-wheel car
with V2 engine and geared transmission, is unveiled at the World Exhibition
in Paris.
1890
The Daimler-Motoren-Gesellschaft (DMG) is founded. Daimler takes a
position as deputy chairman of the Supervisory Board, Maybach is made
a member of the Board of Management.
1891
Maybach leaves the firm and later heads a development centre financed
by Daimler located in the dance hall of a former hotel in Cannstatt.
1894
DMG is threatened by bankruptcy. Gottlieb Daimler also leaves the
firm.
1895
Frederick R. Simms, a British engineer, buys the licensing rights
to the Phoenix engine for 350,000 marks, demanding that Daimler and
Maybach be reinstated in their previous posts at DMG in return. The
1000th engine is completed at the end of the year.
1897
Maybach brings the Phoenix car with its engine positioned above the
front axle up to series production standard.
1900
Gottlieb Daimler dies on March 6. Acting on a suggestion from entrepreneur
Emil Jellinek, Wilhelm Maybach starts to make fundamental changes
to automotive designs. The result is the 35-hp Mercedes, which goes
down in the history books as the first modern-day car.
1901- 1906
Wilhelm Maybach develops engines and chassis in rapid succession to
be used in the Mercedes models, as they are now known.
1902
A large blaze completely destroys the production site in Cannstatt.
The new premises of DMG are established in Stuttgart-Unterturkheim.
1907
Maybach leaves DMG as the result of persistent differences of opinion
with the firm's management. He starts to advise his son Karl Maybach,
who designs engines to power Count Zeppelin's airships.
1916
Stuttgart's technical university presents Wilhelm Maybach with an
honorary doctorate.
1929
Wilhelm Maybach dies on December 29 in Stuttgart.
1996
Wilhelm Maybach is accepted into the Automotive Hall of Fame.
