Why did Alexander Fleming lose interest in his discovery?
“Underlying this was a solid background in scientific thought and method.” But the lack of success with penicillin led him to lose interest. His work went unnoticed and for ten years no one knew of his discovery, which was put on a shelf by its own discoverer.
