Who they are

Karl Benz (1844–1929) was a German engineer who in 1885 designed and built the "Benz Patent-Motorwagen" — the world’s first automobile driven by an internal-combustion engine and designed specifically for road travel rather than adapted from a carriage structure — and patented it in 1886, a date still acknowledged as the starting point of the modern auto industry. Though there had been earlier attempts at steam-powered vehicles, Benz’s contribution was to integrate the gasoline internal-combustion engine, electric ignition, differential, water cooling, and other technologies into a complete mechanical system designed from scratch for automotive use, rather than simply applying an existing carriage or steam-engine structure. Benz himself was conservative and cautious by temperament and lacked confidence in the commercial promotion of the new product; his wife Bertha Benz, without telling her husband, in 1888 drove the Motorwagen alone on a long test drive of about 106 kilometers, solving fuel shortages, mechanical faults, and a string of sudden problems along the way herself, and this widely noticed feat greatly boosted public confidence in the practicality and reliability of the new thing that was the automobile, one of the most famous public-relations events in the early history of the auto industry.

Key stories

A Machine Born for the "Car"

In designing the Motorwagen, Benz abandoned the adaptation approach then common among other inventors of "fitting a carriage with a steam or internal-combustion engine," redesigning completely for internal-combustion drive from the chassis up; this three-wheeler was fitted with his own reciprocating single-cylinder gasoline engine, electric ignition, differential, and other original designs, the first automobile in history truly "designed from scratch" rather than "adapted and cobbled together."

His Wife’s 106-Kilometer Test Drive

In August 1888 Benz’s wife Bertha Benz, without telling her husband in advance, took their two sons and drove the Motorwagen from Mannheim on a long drive of about 106 kilometers to visit her mother in Pforzheim, clearing a blocked fuel line with a hairpin along the way, mending worn wire insulation with a garter, and buying cleaning ligroin at a pharmacy on the road as the first refueling — this first long road test drive greatly proved the reliability of the automobile as a practical means of transport, one of the most famous early public-relations cases in auto-industry history.
