Pierre-Jules Boulanger, often known simply as Pierre Boulanger, was a French engineer and businessman. He directed Citroën as a vice-president and as chairman from 1935 until his death in a car accident. He was known to colleagues as PJB.
Boulanger started working for Michelin in 1918, reporting directly to Édouard Michelin, co-director and founder of the business. Boulanger joined the Michelin board in 1922, and in 1938, he became the company's joint managing director. In December 1934, despite the assistance of the Michelin company, Citroën filed for bankruptcy. In December 1934, Michelin, already the car manufacturer's largest creditor, became its principal shareholder. Boulanger became the assistant of Pierre Michelin, who was the chairman of Citroën. Pierre Boulanger became the vice-president and chief of the Engineering and Design department. He became president in 1937 after the death of his friend and kept his position until his death. He also jointly managed the Michelin company. As part of the policy to reduce costs, wages were decreased and the launching of the 22 V8 was cancelled. The policy bore fruit and Citroën recovered.
WW2
During the occupation of France in the Second World War, Boulanger refused to meet Dr. Ferdinand Porsche or communicate with the German authorities except through intermediaries. He organized a 'go slow' of production of trucks for the Wehrmacht, many of which were sabotaged at the factory, by putting the notch on the oil dipstick in the wrong place resulting in engine seizure. In 1944 when the Gestapo headquarters in Paris was sacked by members of the French Resistance, his name was prominent on a German blacklist of the most important 'Enemies of the Reich' to be arrested in the event of an allied invasion of France.
In 1936, Boulanger initiated a project to create the TPV, which became 2CV in 1948. His specification for the new model was characteristic of the man: The 2CV was known for its great capacity of work and its absence of ostentation. In 1947, the Citroën H Van was introduced – this utilitarian commercial van was sold until 1981. He died at Broût-Vernet, Allier, in a car crash in a Citroën Traction Avant on Sunday, 12 November 1950, while on the main road between Clermont-Ferrand and Paris.
