Ernst Boris Chain was a German-born British biochemist renowned for his work in understanding antibiotics. He played a key role in discovering how penicillin works, which revolutionized medicine by enabling the treatment of bacterial infections. Chain’s research helped identify how penicillin kills bacteria without harming humans, leading to effective antibiotics widely used today. He was awarded the Nobel Prize in Physiology or Medicine in 1945, sharing it with Alexander Fleming and Howard Florey. His contributions significantly advanced microbiology and medical science, saving countless lives through improved infection treatments.
