Biography Scientist, inventor, statesman, printer, philosopher, musician, and economist: Benjamin Franklin was all of these during his long life, but most of all he was curious. His curiosity about things led him to investigate the way they work, and sometimes to invent ways to make them work better. For example, he had poor vision and needed glasses to read. He got tired of constantly taking them off and putting them back on, so he figured out a way to make his glasses let him see both near and far. He had two pairs of spectacles cut in half and put half of each lens in a single frame. Today, we call glasses like these bifocals. In his role as a statesman, Franklin sailed to Europe many times. These voyages piqued his curiosity about ocean currents, and from the data he collected while onboard ship he created the first map of the Gulf Stream.
