In 1928, the scientist Alexander Fleming was trying to grow the bacterium Staphylococcus, and by chance, discovered that it would not grow in the presence of a mold that he named Penicillium. In 1939, Ernst Chain and Howard Florey purified penicillin, and in 1941, penicillin was first used to treat bacterial diseases. In 1945, Alexander Fleming, Ernst Chain, and Howard Florey received the Nobel Prize in medicine for the discovery and isolation of penicillin. These facts show that —

Florey and Chain unfairly used Fleming’s work and should not have received the Nobel Prize

whenever possible, the Nobel Prize should be given to more than one person
