Introduction to Alexander Fleming
Alexander Fleming was a very important scientist in the history of medicine. He was born in Scotland in 1881. When he was a teenager, he moved to London. There, he studied hard and became a doctor.
The Discovery of Penicillin
In 1928, while studying influenza (which is commonly known as the flu), Fleming made a surprising discovery. He noticed that a certain type of mold was killing bacteria in his petri dishes. This mold was later named penicillin.
Fleming’s discovery was crucial. However, it was not until later that two other scientists, Howard Florey and Ernst Chain, helped turn penicillin into a medicine that people could use. By the 1940s, penicillin was being produced in large amounts and used to treat infections.
Achievements and Legacy
Fleming was recognised for his work and won the Nobel Prize in Medicine in 1945. Today, penicillin is still widely used to treat bacterial infections, making Fleming’s discovery one of the most important in modern medicine.
