Benjamin Franklin believed in bettering the world around him. Never patenting or receiving financial reward, Franklin believed that his inventions and improvements were meant only to benefit society. Beginning with the invention of swim flippers at the age of 14, he went on to invent the glass armonica, the Franklin stove, and the bifocals. He also made useful improvements to such things as street lamps and the urinary catheter. Arguably, his most important invention was the lightning rod. Since first proposing the use of rods to draw electrical fire from the clouds in 1750, his invention has saved millions of structures from fire. This keychain measures 2 1/2H X 2 1/4W.
