Reply:  Binyamin invented electricity, not the bulb, but here's the timeline....


600 B.C.
Thales of Miletus writes about amber becoming charged by rubbing - he was describing what we now call static electricity.

1600
English scientist, William Gilbert first coined the term "electricity" from the Greek word for amber. Gilbert wrote about the electrification of many substances in his "De magnete, magneticisique corporibus". He also first used the terms electric force, magnetic pole, and electric attraction.

1660

1675
Robert Boyle discovered that electric force could be transmitted through a vacuum and observed attraction and repulsion.

1729

Dutch physicist, Pieter van Musschenbroek invented the "Leyden Jar" the first electrical capacitor. Leyden jars store static electricity.

1747
