Louis Bachelier
Louis Jean-Baptiste Alphonse Bachelier (March 11, 1870 – April 28, 1946) was a French mathematician at the turn of the 20th century. He is credited with being the first person to model the stochastic process now called Brownian motion, which was part of his PhD thesis The Theory of Speculation, (published 1900).
His thesis, which discussed the use of Brownian motion to evaluate stock options, is historically the first paper to use advanced mathematics in the study of finance. Thus, Bachelier is considered a pioneer in the study of financial mathematics and stochastic processes.

“You ask: What is it that philosophers have called qualitative states? I answer, only half in jest: As Louis Armstrong is said to have said when asked what jazz is, ‘If you got to ask, you ain’t never gonna get to know.’”
—Ned Block (b. 1942)
