Paul Daimler

Paul Daimler (September 13, 1869 – December 15, 1945) was a German mechanical engineer who designed automobiles. He was the eldest child of Gottlieb Daimler who founded Daimler-Motoren-Gesellschaft and (with Wilhelm Maybach) invented the petrol engine.

The Austro-Daimler armoured car

After studying at the Technische Hochschule Stuttgart, he worked in his father's factory in Cannstatt. On November 10, 1885 he travelled with his father in the "riding car"—the world's first motorcycle—from Cannstatt to Untertürkheim. In 1902, Paul was sent to the general partners of Austro-Daimler, where he became the technical director. In 1903, he designed an armoured car. From 1907 to 1922 he was Technical Director of Daimler-Motoren-Gesellschaft Untertürkheim, Sindelfingen and Berlin-Marienfelde. On July 1, 1923, he joined Horch, part of Argus Motoren Gesellschaft and made a name for himself there as a developer in the department of motor aircraft engines, remaining until 1928.

Examples of his work include the hydraulic valve lifters, which he introduced in 1931.
