1, brand introduction: Citroen was founded by Andre Citroen. When he 1878 was born in Paris, France, his family did not expect that the Citroen automobile brand he founded decades later would make the family a household name. 2. Development course: Citroen was recruited as an artillery captain during the First World War. When he found that he was short of ammunition, he volunteered to set up a factory to produce shells. Here, his organizational management ability was fully exerted, which not only made the daily output of artillery shells reach a record 50,000 pieces, but also enabled women to take part in the work due to proper organization, thus allowing more men to quit the war.
