The Riemann Integral was developed as a way to calculate the area under a curve. Then came a function that was impossible to integrate. This dilemma would lead one mathematician, Henri Lebesgue, to invent an entirely new approach. The Lebesgue Theory of Integration was a much better theory of integration and it would ultimately change the way we think about the integral forever.
