List of the entire famous scientist Alessandro Volta(1745-1827) An Italian Physicist who was a pioneer in the development of electricity. He created the first electric battery in 1800. This battery gave the world its first continuous‚ reliable source of electric current‚ and led to all important discoveries of the use of electricity. The unit of measuring electromotive force (emf)‚ Volt(v) is named after him. He also proposed the law that the air expands at a constant rate with increasing temperature
