96. BENJAMIN FRANKLIN’S LIFE
Benjamin Franklin is one of the most famous individuals in American history. As a writer, an inventor, and a
founder of the United States of America, he greatly influenced the world he lived in. Franklin was born in
1706 in Boston, Massachusetts. He was one of 17 children, which meant that his life was not very easy. Most
of the time, he had to take care of himself. However, this taught Franklin the importance of being independent
and clever. At 12, Franklin went to work for his brother James, who owned a newspaper. Franklin wrote
under a fake name so people wouldn’t know how young he was. His pen name was Silence Dogood. Readers
loved Silence Dogood and never suspected that “she” was a teenager named Benjamin Franklin. When he was
older, Franklin left his brother’s newspaper and started his own printing business. His paper, The
Pennsylvania Gazette, became a leading newspaper at the time. In 1732, Franklin began publishing Poor
Richard’s Almanack, which he printed yearly for more than two decades. Like other almanacs, Poor Richard’s
Almanack was filled with general information, like planting dates, weather predictions, and advice. But there
was much more to Benjamin Franklin than his writing. He spent a lot of time working on inventions to help
society. The Franklin stove, which warmed people’s houses, is one such example. In the 1750s, he became
famous worldwide for his experiments with electricity and the invention of the lightning rod. Franklin used
his popularity to work for causes he believed in, like American independence. In 1778, he persuaded the
French to support the Americans during their war for freedom from Britain. Franklin’s writings, inventions,
and leadership will never be forgotten. Although he died centuries ago, the bright flame of his legacy still
warms the world.
