the lightbulb
Edison did not invent the electric light. Humphry Davy demonstrated an arc lamp in 1802, and at least twenty inventors produced incandescent bulbs before him; Joseph Swan demonstrated one in Newcastle in 1878 and was granted a British patent, which is why Edison eventually had to merge with him as Ediswan. What Edison produced in October 1879 was a bulb that lasted long enough and cost little enough to sell, together with the generating and wiring system to make it useful.
the Statue of Liberty
Dedicated in October 1886, the statue predates the Eiffel Tower by two and a half years — and its internal iron framework was designed by Gustave Eiffel, who went on to use what he learned on the tower. It arrived from France in 214 crates and the American side had to raise the money for the pedestal by public subscription, which nearly failed. The copper skin is about 2.4 mm thick, roughly the thickness of two pennies.
