Bertha Benz

Cäcilie Bertha Ringer was born on 3 May 1849 to a wealthy family in Pforzheim in the Grand Duchy of Baden.

Two years before her marriage to Karl Benz, she used part of her dowry to invest in his failing iron construction company. As an unmarried woman, she was able to do so; after she married Benz, according to German law, Bertha lost her legal power to act as an investor. On 20 July 1872, Bertha Ringer married Karl Benz. As he moved on to a new manufacturing venture, Benz & Cie, he continued to use her dowry as financial support.

Karl finished work on his first horseless carriage in December 1885. Bertha served as a field tester, contributing to the design of the Motorwagen by adding wire insulation and inventing leather brake pads to supplement the wooden brakes when they failed. Moreover, she identified several key areas of opportunities – such as the fuel line design – that Karl later improved. In addition to her contributions to the machine’s design, Bertha helped finance the development of the Motorwagen. She would hold patent rights under modern law, but as a married woman, she was not allowed to be named as an inventor on the patent at that time.

In 1886, Benz presented the Patent-Motorwagen automobile to the world. Within the decade, 25 vehicles had been built. With cutting-edge bicycle constructions, the Model I was the original Patent Motor Car and the world's first automobile.

On 5 August 1888, 39-year-old Bertha Benz drove from Mannheim to Pforzheim with her sons Richard and Eugen, thirteen and fifteen years old respectively, in a Model III, without telling her husband and without permission of the authorities, thus becoming the first person to drive an automobile a significant distance, though illegally. Before this historic trip, motorized drives were merely very short trials, returning to the point of origin, made with assistance of mechanics. Following wagon tracks, this pioneering tour covered a one-way distance of about 106 km (66 mi).

In 1925 Karl Benz wrote the following in his memoirs: "Only one person remained with me in the small ship of life when it seemed destined to sink. That was my wife. Bravely and resolutely she set the new sails of hope."

Benz died in her villa in Ladenburg in 1944, where the workshop of Karl Benz had been built after they had moved there in 1906 and he established a solely family-held business, Benz and Sons. Karl Benz had died in 1929, after the success of Daimler-Benz was assured. Members of the family resided in the home for thirty more years. The Benz home now has been designated as historic and is used as a scientific meeting facility for a nonprofit foundation, the Gottlieb Daimler and Karl Benz Foundation, that honors both Bertha and Karl Benz for their roles in the history of automobiles.

In 2008, the Bertha Benz Memorial Route was officially approved as a route of the industrial heritage of mankind, because it follows Bertha Benz's path during the world's first long-distance journey by automobile in 1888. Now it is possible to follow the 194 km of signs indicating her route from Mannheim via Heidelberg to Pforzheim (Black Forest) and back.

On 25 January 2011 Deutsche Welle (DW-TV) broadcast worldwide in its series, Made in Germany, a TV documentary on the invention of the automobile by Karl Benz, highlighting the very important role of his wife, Bertha Benz. The report is not only on the history of the automobile, but takes a look at its future as well, shown by the Bertha Benz Challenge on 10 and 11 September 2011.

In 2011, a television movie about the life of Karl and Bertha Benz was made, titled Karl & Bertha, which premiered on 11 May and was aired by Das Erste on 23 May. A trailer of the movie and a "making of" special were released on YouTube.

In honor of International Women’s Day in 2019, the modern Daimler company commissioned a four-minute advertisement dramatizing portions of Bertha Benz’ 1888 journey. The ad was created by Berlin-based ad agency Antoni (the lead European agency for Mercedes-Benz), and directed by Sebastian Strasser via his production company, Anorak Film.
