Alexander Fleming was a doctor and bacteriologist who discovered 

penicillin, receiving the Nobel Prize in 1945.

 

Alexander Fleming was born in Ayrshire, Scotland, on August 6, 1881, and studied medicine, serving as a physician during World War I. Through research and experimentation, Fleming discovered a bacteria-destroying mold which he would call penicillin in 1928, paving the way for the use of antibiotics in modern healthcare. He was awarded the Nobel Prize in 1945 and died on 

March 11, 1955.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

During World War I, Fleming served in the Royal Army Medical Corps. He worked as a bacteriologist, studying wound infections in a makeshift lab that had been set up by Wright in Boulogne, France. Through his research there, Fleming discovered that antiseptics commonly used at the time were doing more harm than good, as their diminishing effects on the body's immunity 

agents largely outweighed their ability to break down harmful bacteria -- therefore, more soldiers were dying from antiseptic treatment than from the infections they were trying to destroy.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

In 1946, Fleming succeeded Almroth Edward Wright as head of St. Mary's Inoculation Department, which was renamed the Wright-Fleming Institute. 

Additionally, Fleming served as president of the Society for General 

Microbiology, a member of the Pontifical Academy of Science, and an honorary member of nearly every medical and scientific society in the world.
