One of the Founding Fathers of the United States, a drafter and signer of the United States Declaration of Independence, and the first United States postmaster general, Benjamin Franklin was a lot of things. He was a writer, scientist, statesman, diplomat, printer, publisher, political philosopher, and inventor. Some of his most famous inventions are the lightning rod, bifocal glasses and the Franklin stove – but there are so many other things that you may not know were created by Benjamin Franklin.
His first documented invention was swimming fins. At age 11, Franklin made a pair of oval wooden planks with holes in the center for his thumbs. He used those for extra thrust while swimming.
