Everyday life is constantly changing and improving thanks to the ingenious ideas of famous inventors past and present. What once seemed impossible is now possible, such as Leonardo da Vinci’s forward-thinking concepts for flying machines (airplanes), Benjamin Franklin’s useful inventions like bifocals and the lightning rod, and Alexander Graham Bell’s revolutionary “talking machine” (telephone).
An inventor is a person who makes new inventions, devices that perform some kind of function. The devices are mostly electrical or mechanical. Someone that invents new ideas or methods on how to do things may also be called an inventor.
Many inventors make small changes to old inventions. For example, people have invented new ways to make clocks over history. Early clocks were sundials, later clocks used water, and pendulums. Modern clocks are often electronic. Other machines such as vehicles are made of many inventions.
