12. Franklin Became The First Person To Map The Gulf Stream
In total, Benjamin Franklin made about eight trips along the Atlantic Ocean. Because of this, he started to know the waters well. Franklin also noted that there was something off about the maps along the Atlantic Ocean. Therefore, Franklin took it upon himself to fix the map. He corrected the route by adding what became known as the Gulf Stream, which is a swift and warm current that originates from the Gulf of Mexico and stretches to the tip of Florida.
