This chapter describes the technological transitions from the invention of a multitude of electrical devices to “the first age of electricity.” It begins with a description of the different types of electrical inventions and devices that were the precursors of modern day electrical technology. Benjamin Franklin invented a lightning rod and two different types of electric motor; the works of Luigi Galvani and Alessandro Volta in the field of static electricity are described next. Galvani, an obstetrician, performed a number of experiments using small animals such as frogs to demonstrate that static electricity is present in the bodies of animals. The chapter concludes with a description of the contribution made by Humphry Davy in the field of galvanism.
