Fritz Haber was a German chemist born on December 9, 1868. He is best known for developing the Haber-Bosch process, which synthesizes ammonia from nitrogen and hydrogen. This process revolutionized agriculture by enabling the mass production of fertilizers, significantly increasing crop yields. Haber's work had a profound impact on both science and society. However, he is also associated with the development of chemical weapons during World War I, which raised ethical concerns about the use of scientific advancements in warfare. He received the Nobel Prize in Chemistry in 1918 for his contributions to chemistry.
