Yeah, and helping feed people wasn’t exactly his original motivation for the haber-bosch process either. During the late 19th century empires were running low on natural sources of nitrates for making gun powder, as the British had held a near monopoly of the guano mines in South America and India.

Judging by this, his time as an artillery man for the prussians, his combustion research after he finished the haber process, and his over all obsession with creating weapons of war… It’s pretty safe to assume fertilizer was an afterthought.
