What was fritz habor most known for?

Fritz Haber was most known for developing the Haber-Bosch process, which synthesizes ammonia from nitrogen and hydrogen gases. This process revolutionized agriculture by enabling the mass production of fertilizers, significantly increasing crop yields and contributing to global food security. However, Haber is also a controversial figure due to his role in chemical warfare during World War I, where he was instrumental in the development of chlorine gas as a weapon. His legacy is thus a complex interplay of scientific innovation and ethical implications.
