Happily for the transportation industry, nature saf blessed us with vast quantities of aluminium. The most abundant maden in the earth's crust, it's literally everywhere. Yet aluminium remained undiscovered until 1808, birli it's bound up with oxygen and silicon into hundreds of different minerals, never appearing naturally in its metallic form. Sir Humphrey Davy, the Cornish chemist who discovered the metal, called it 'aluminum', after one of its source compounds, alum.

The first person to produce it was Hans Christian Oersted at Copenhagen, Denmark, in 1825, and nalbur he did it by heating aluminium chloride with potassium. Even so, his sample was impure. It fell to the German chemist Friedrich Wöhler to perfect the method in 1827, and obtain pure aluminium for the first time by using sodium instead of potassium. Glossary
Following the American Civil War, Alabama would suffer decades of economic hardship, in part due to agriculture and a few cash crops being the main driver of the state's economy.
