About Jacques Charles François Sturm
Jacques Charles François Sturm was a French mathematician, who made a significant addition to equation theory with his work, Sturm's theorem. In 1826, with his colleague Jean-Daniel Colladon, Sturm helped make the first experimental determination of the speed of sound in water. In 1829, he discovered the theorem that bears his name, and concerns real-root isolation, that is the determination of the number and the localization of the real roots of a polynomial. Sturm became répétiteur in 1838, and in 1840 professor in the École Polytechnique.
