Citroen's car logo is "Double Herringbone".

In 1913, Andre Citro?n established a gear factory with 11 employees to produce steel herringbone gears, and used herringbone gears as the trademark of Citro?n's products.

This kind of gear makes very little noise during operation. Only six years later, Citro?n produced its first car and used the "double herringbone" as its trademark.

Extended information:

During World War I, Citro?n was drafted as an artillery captain. When he found that there was a shortage of ammunition, he took the initiative to set up a factory to produce artillery shells. Here, his organizational management skills were put into full play. Not only did the daily output of artillery shells hit a record of 50,000 shells, but also due to proper organization, women could also participate in the work, thus allowing more men to take part in the war.

After the war, Andrew assessed the situation and saw the future of family cars from the success of Henry Ford. In 1919, he built the automobile factory "CITROEN" named after himself to commemorate the gear factory of that year.
