Sir Alexander Fleming (NS&I's founder)

Sir Alexander Fleming was a Scottish scientist best known for discovering penicillin in 1928, the world’s first widely effective antibiotic. This groundbreaking find revolutionized medicine by enabling the successful treatment of bacterial infections that were often fatal before. Fleming’s discovery came from observing that a mold called Penicillium notatum sneaked into his petri dishes and killed bacteria, leading to the development of antibiotics that save millions of lives today. While he is not the founder of NS&I (National Savings & Investments), Sir Alexander Fleming’s contributions to medicine have had a profound and lasting impact on public health.
