Alexander Fleming

By: Amanda Hill


Alexander Fleming was born on August 6th, 1881, in Scotland. He was one of eight children. Alexander moved to London at age 13 with his brothers. He was forced to work at a shipping office while he was in school. Later in life he got a grant from his uncle and he got to go to medical school, where he got the training needed to be a doctor during WW1. He had no way of stopping infections, and that sparked his interest in antibiotics. In 1922 Fleming found uses for Lysozyme. Latter he came back to his work and made the biggest leap in medicine for years to come, Penicillin. Fleming then became the director of the institute. He held that position until 1955. In 1945 he received the Nobel Prize for physiology. He died on March 11th, 1955.

Impact on the 1920's

He made the biggest leaps in medicine in the 20th century. He is most famous for discovering Lysozyme and penicillin. His discoveries are still used today.

Discovery of Lysozyme

Lysozem has a natural antibacterial effect on the human body. It can be found in tears, and egg whites.

"No man ... has had a more profound influence on the contemporary history of the human race." -André Maurois

Penicillin : The First Antibiotic

His discovery happened because his lab was very disorganized. One day he was cleaning out his sink full of Petri dishes, one of which had some mold growing on it. It made him stop and look closely at it because the bacteria around the mold was dead. This lead him to discover Penicillin.
