Benjamin Franklin (1706-1790)
He was one of the founders of the United States of America and an outstanding scientist and inventor. Born in Boston, Massachusetts, into a modest family of 17 children, he showed an interest in knowledge and innovation from a young age.
At the age of 12, Franklin began working as an apprentice in his older brother’s printing shop, and at 17 he moved to Philadelphia, where he established his own printing shop. During his career as a printer, Franklin was also involved in writing and publishing various texts, such as the famous Poor Richard’s Almanac, which contained practical advice for everyday life.
In addition to his work as a printer and writer, Franklin made important contributions to science and technology. In 1752, he conducted a famous experiment in which he demonstrated the electrical nature of lightning. Using a kite with a metal key attached to its end, Franklin succeeded in collecting the electric charge generated by lightning in a Leyden bottle, which proved that lightning was a form of electricity.
Franklin also invented several useful devices, such as the lightning rod, which protected buildings from lightning, and the bifocal, which allowed correction of vision at different distances in a single lens. He also developed a method for cooling liquids using evaporation, which is known as the absorption refrigeration cycle.
In addition to his scientific and technological achievements, Franklin also had an outstanding political career. He was one of the drafters of the U.S. Declaration of Independence in 1776, and was one of the negotiators of the 1783 Treaty of Paris, which ended the American War of Independence and recognized the independence of the United States.
Franklin was a leading figure in his time and is remembered as one of the founding fathers of the United States and one of the greatest scientists and inventors in history. His work and legacy continue to be studied and admired throughout the world.
Alessandro Volta (1745-1827)
