Sometimes, the greatest advance are those that we didn't know were possible, says Marla Ahlgrimm. The following are a few pharmaceutical discoveries that have changed the world. They are all related in that they were all found by complete accident.
Penicillin
If you don’t know the name Alexander Fleming, Marla Ahlgrimm says that you should. As the scientist that discovered penicillin, Fleming is directly responsible for saving countless lives throughout the years. The discovery was made in the early 1900s during the Spanish flu pandemic. A bit of dust that made its way into the petri dish, where it then molded. An eagle-eyed Fleming noticed that the area around the mold was blissfully bacteria free. The resulting antibiotic was soon being used across the globe.
