Julius Ludwig Weisbach (born

Weisbach studied at the "Bergakademie" in Freiberg from
1822 -1826 . After that, he studied withCarl Friedrich Gauss inGöttingen and withFriedrich Mohs inVienna .In
1831 he returned to Freiberg where he worked as mathematics teacher at the local Gymnasium. In1833 he became teacher for Mathematics and the Theory of Mountain Machines at the Freiberg "Bergakademie". In1836 he was promoted to Professor for applied mathematics, mechanics, theory of mountain machines and so-called "Markscheidekunst".Weisbach wrote an influential book for mechanical engineering students, called "Lehrbuch der Ingenieur- und Maschinenmechanik", which has been expanded and reprinted on numerous occasions between
1845 and1863 .He also refined the Darcy equation into the still widely used
Darcy-Weisbach equation .elected Publications
