No one invented Aluminum. It's a naturally occurring element, Atomic Number 13. Until late in the 19th century, aluminum was far more precious than gold or platinum. In spite of it's being the third most common element in the earth's crust, it was difficult to extract, so was extremely rare in any pure form. A pound of aluminum would have cost $100,000 in 1885, but because of the work of Charles Martin Hall in that year, a process for refining the metal inexpensively from ore made it more readily available, and the price plummetted. This once rare metal is now one of the most common construction metals in the world. Only steel is more used.

Nobody actually invented them. Ski poles were first used since the start of skiing. But I suppose you can call Ed Scott the inventor of the modern ones, since he, in 1958, was the one with an idea of aluminum poles. The aluminum poles are still the main types of ski pole on the market.
