Sir Ernst Boris Chain

Sir Ernst Boris Chain was a pioneering biochemist known for his significant role in discovering how antibiotics, like penicillin, fight bacteria. He helped unravel the chemical processes bacteria use to grow and how antibiotics can block those processes. His work was crucial in developing antibiotics that have saved millions of lives by treating infections. Chain was awarded the Nobel Prize in Physiology or Medicine in 1945, along with Alexander Fleming and Howard Florey, for their collective efforts in making antibiotics widely accessible. His research transformed medicine and remains a foundation for antibiotics used today.
