It was a no smaller challenge to scale up Haber’s experimental success to a commercial enterprise. Under the leadership of Carl Bosch, an expert in chemical as well as metallurgical engineering who joined BASF in 1899, success was achieved in just four years. The world’s first ammonia synthesis plant began to operate at Oppau in September 1913, and the term “Haber-Bosch process” has endured ever since.[17]
