He had obtained a patent on the cotton gin but it proved to be unenforceable. Whitney’s priorities, henceforth, were money and manufacturing. Whitney never seemed, as one historian noted, to care about slavery “one way or the other.”

A quick glance at the numbers shows what happened. American cotton production soared from 156,000 bales in 1800 to more than 4,000,000 bales in 1860 (a bale is a compressed bundle of cotton weighing between 400 and 500 pounds).
