"It began modestly in 1757 with one small sawmill. Less than 140 years later, Niagara Falls became the world's leading producer of electrical power. Essential to power development at Niagara were Nikola Tesla, George Westinghouse, William B. Rankine, J. P. Morgan, Edward Dean Adams, and John Jacob Astor IV; crucial to its realization were the hundreds of now-nameless workers who hacked the power station's wheel pit from obstinate bedrock, and tunnelled its tailrace for almost two miles beneath the city.
"With the first generation of power in 1895, electrical power became plentiful and inexpensive. Revolutionary new electro-chemical and electro-metallurgical industries flocked to Niagara. For much of the Twentieth Century, Niagara Falls was the world's center of electrochemical and electrometallurgical production."
