William Gilbert
William Gilbert suggested that there were 2 kinds of electricity. Around 1600, He experimented with this idea. He rubbed glass and silk together which made a vitereious charge. He rubbed amber and fur which made a resinous charge. His experiments proved that objects with the same charge repell. The picture is a page from his book De Magnete -
Thales
Thales was a greek man who discovered static electricity. He discovered it by rubbing an amber and wool together. This charged the amber which made grass fly upward to cling to the amber. He discovered this around 600 BCE -
Benjamin Franklin
Benjamin Franklin invented the lightning rod. His main experiment which led to the break threw, was an extremely famous experiment. This experiment was conducted on a stormy day, where Franklin fastened a stiff wire to the top of a kite and at the end of the kite string, he tied a key. The string of the kite conducted electricity. The sparks jumped from the key. This proved his theory that lightning was really just a large spark. -
Charles de Coulomb
In the 1780s, french physicist Charles de Coulomb was one of the first scientists to experiment with electric charges. He experimented with atracting and repelling charges with a wire. This experiment made one of the laws of electricity. This law is "The force of attraction or repulsion between two charged objects changes according to the ratio of the squares of their distance apart" -
Luigi Galvani
Luigi Galvani, an italian doctor, was examing a dead frog, and realized the frog would move if you put two pieces of metal on it. He predicted that the electricity travelled from the metal, threw the frog, and to the other piece of metal. He was correct. He tryed this again, but this time with lightning. He guessed that the spark of the storm would hit his railing and move threw the hook and toward the frog. This would make it move. He was right. He had now discovered electricity. -
Alessandro Volta
Italian Alessandro invented the battery. This invention was advanced later. -
Oersted
Oersted published his discovery of the interaction between electricity and magnetism. It was written in latin, but was translated into many languages. This had his discovery of a connection between electricity and magnetism. -
Samuel Morse
American Samuel Morse invented the telegraph in 1837. He was originally a painter, but had the idea for the telegraph in 1832 and stopped painting to make his idea reality. His machine consists of a code of dots that is sent using electricity. His invention was a huge sucess. The first version could send a message 60km. -
Henry Woodward and Thomas Edison
Thomas Edison bought the patent for the light bulb from Canadian Henry Woodward. This means that the lightbulb was invented by a canadain. For proof, visit this website. http://inventors.about.com/od/cstartinventions/a/Canadian.htm -
Alexander Graham Bell
Canadian inventor Alexander Graham Bell invented the telephone using a battery, a sheet of metal and a coil of wire wrapped around a magnet. -
Thomas Ahearn
Thomas Ahearn invented the electric car heater in 1890. This canadian also invented the electric cooking range. -
Peter Cooper Hewitt
American unknown inventor Peter Cooper Hewitt invented the fluorescent light bulb. -
Richard Keefer
17 year old canadian Richard Keefer invented a battery that runs on garbage. It lasted much longer than a store bought battery and cost the same price. -
Anita Luszszak
When Anita was only 15, the canadian girl invented a pulsating generator that uses less energy to generate power. In the international competition for inventors, she won gold.
