1) In 1731 Ben Franklin founded in Philadelphia what was probably America's first public library. He also organized Philadelphia's first fire company, introduced methods for the improvement of street paving and lighting, and devised means to correct the
excessive smoking of chimneys. In 1747 Franklin began his electrical experiments. He advanced a defensible theory of the Leyden
jar and proposed an effective method of demonstrating that lightning is an electrical phenomenon. He also invented the lightning
rod and offered an explanation of the two kinds of electricity, positive and negative. Franklin's proposals for changes in education
led to the establishment in 1751 of what would become the University of Pennsylvania
2) Born in Milan, Ohio, Thomas Edison began experimentation with printing presses and with electrical and mechanical
apparatuses in his youth. While working as a telegraph operator, he made his first important invention, a telegraphic repeating
instrument that enabled messages to be transmitted automatically over a second line without an operator. Edison's crowning
achievement in telegraphy was his invention of machines that permitted simultaneous transmission of several messages on one
line. His invention of the carbon telephone transmitter was important in the development of the telephone, invented by the American
physicist Alexander Graham Bell. In 1877 Edison announced the first phonograph
