Jacques Charles François Sturm (29 September 1803 – 15 December 1855) was a French mathematician, who made a significant addition to equation theory with his work, Sturm's theorem.[1]
Early life
Sturm was born in Geneva, France in 1803. The family of his father, Jean-Henri Sturm, had emigrated from Strasbourg around 1760—about 50 years before Charles-François's birth. His mother's name was Jeanne-Louise-Henriette Gremay.[2]
In 1818, he started to follow the lectures of the
At the end of that year, Sturm stayed in Paris for a short time following the family of his student. He resolved, with his school-fellow Jean-Daniel Colladon, to try his fortune in Paris, and obtained employment on the Bulletin universel.[3]
Discovery
In 1829, he discovered the
Work
Sturm benefited from the 1830 revolution, as his Protestant faith ceased to be an obstacle to employment in public high schools. At the end of 1830, he was thus appointed as a professor of Mathématiques Spéciales at the
He was chosen a member of the
He was the co-eponym of the Sturm–Liouville theory with Joseph Liouville.
In 1826, with his colleague Jean-Daniel Colladon, Sturm helped make the first experimental determination of the speed of sound in water.[2]
Death
In 1851 his health began to fail. He was able to return to teaching for a while during his long illness, but died in 1855.[2]
