Humpry's discovery basically caused the aluminum industry, solar panels, ect. He discovered this by running electricity to melted pot ash. -
Synthesis of Urea
Two inorganic chemicals created artificial urea. This was discovered by Friedrich. Although, this doesn't seem like a big deal now, back then it was. -
Atoms Have Signatures of Light

Atomic Theory
Dalton propose that matter is made up of atoms that are indivisible & indestructable. -
Plastic
Plastic was founded by exploting the long string molecules of plants, thus creating the first plastics. Plastics are essentially polymers. -
Electrons form Chemical Bonds
Two atoms combined a different substance. Gilbert was the one who discoved this. -
Chemical Structure
Agust Kekule made a system, he represented atoms by their symbols & added marks to show how they bonded w/ each other. -
Fullerenes
One special clustered of carbon, 60 carbons to be exact. This was named Buckminster because he was created the geodesic dome that resembled the carbons chain.
