Bertha Benz was a German automotive pioneer. She was the business partner, investor and wife of automobile inventor Carl Benz. On 5 August 1888, she was the first person to drive an internal-combustion-engined automobile over a long distance, field testing the Benz Patent-Motorwagen, inventing brake lining and solving several practical issues during the journey of 105 km. In doing so, she brought the Patent-Motorwagen worldwide attention and got their company its first sales. Bertha Benz was not allowed to study in the Grand Duchy of Baden, and her financial and practical engineering contributions have long been overlooked until the 21st century.
