A Jewish inventor
was among many who played a pioneering role in the American development
of the steam engine. Joseph Simon, of Lancaster Pennsylvania, in partnership
in a joint workshop with William Henry, experimented with that form of
mechanism in 1763. A bright young apprentice, Robert Fulton, was then
under their tutelage. Fulton went on to construct the first steamboat
in 1807.2
In the mid-nineteenth
century, some audacious inventors experimented with steam-power for family
transportation. The necessity for maintaining a firebox and other considerations
made that type of mechanism too unwieldy, troublesome and impractical.
In 1854, the
German/Jew, M. Davidson of Darmstadt replaced the horse with an electric
motor and the harness with a transmission and thus produced the first
practical auto-mobile.3 Davidson
was far ahead of his time, for while the state of the art at that time
left the electric battery inadequate for sustained travel, it does appear
that relatively pollution-free electricity may eventually become an energy
of choice for family vehicles.
Shortly after
Davidson drove his horseless carriage around Darmstadt, Siegfried Marcus,
of Vienna, was experimenting with the production of illumination by igniting
a mixture of gasoline and air with a stream of sparks. Marcus recognized
from the violent reaction that ensued, that, if controlled, it could become
a valuable power source for a more effective, efficient, practical engine
than one powered by steam. He constructed a two-cycle motor in which such
a mixture was introduced into the cylinder and fired with a spark. Marcus
then geared it to the rear wheels of a cart. The engine was started by
having a strong man lift the back of the cart and spin a rear wheel!
In 1864, the
first combustion-engined vehicle made a successful run of over two hundred
yards.
During the
next ten years Marcus worked on and off on his engine, pioneering and
patenting many fundamental innovations, such as magneto ignition, the
rheostat, the telegraph relay. In 1870, and again in 1874-5, Marcus built
improved models of combustion-engined automobiles, and drove them through
the streets of Vienna.
Marcus registered
patents for the noisy putt-putting machine in 1882.

| A combustion-engined
automobile built in 1874 by Siegfried Marcus and patented in 1882.
The first model of a self-propelled, benzine-fueled vehicle had
been invented by Marcus ten years earlier. |
Its attributes
were remarkable for its time. Siegfried Marcus introduced a number of
ground-breaking innovations that made his combustion motor a standard
for all that followed. Some of these inventions have endured into modern
cars.
The vehicle
Marcus patented was driven by a single cylinder, four-stroke, water-cooled
engine. The cylinder measured 100 by 200 mmm., and had a volume of 1570
cc. It had a mechanically-operated slide inlet valve and a poppet exhaust
valve. It had a low-tension magneto ignition and a surface carburetor.
It was geared with a single forward speed. The power was transmitted by
a metal-to-metal cone clutch, and was belted to a sold rear axle. In engaged
the wheel with a slipping clutch differential to the nearside rear hub.
It had center-pivot steering and shoe brakes.
At the time,
vehicles were pulled by animals from the front. Marcus determined that
to reduce the transmission length and facilitate steering, mounting the
motor in the rear was more practical and economical.
21 years after
Marcus produced the first automobile, 15 years after he drove his first
sophisticated model through the Viennese streets, and over 2 years after
he patented his invention, another combustion-engined vehicle appeared.
It was produced by Carl Benz and his Jewish partner, Max Rose. "(It
was) a three-wheeler powered by a two-cycle, one-cylinder engine."4
