Karl Weierstrass Biography
Birthday: October 31, 1815 (Scorpio)
Born In: Ennigerloh
Karl Theodor Wilhelm Weierstrass was a German mathematician, who for his contributions to mathematics is often regarded as “the father of modern analysis.” Because of his amazing skills in the field of mathematics, he gained wide recognition all over the world. Even though he had to leave the University of Bonn without completing his graduation and getting his degree, he continued his studies at the University of Munster, eventually becoming a teacher, not only of mathematics, but also of physics, botany and gymnastics. It was Weierstrass, along with Augustine Cauchy, who had stated the modern analysis theory, which was one of his major achievements in his career. The first detailed definitions of fundamental concepts like differentiability, limit, continuity and convergence were also given by him. In the year 1854, he achieved the biggest success of his career, as well as fame worldwide, with the publication of a paper providing the solution of inversion of hyper elliptic integrals. He also helped devise the Weierstrass-Erdman condition, which gives sufficient conditions for an extreme to have a corner along a given extreme, as well as allows one to find a minimizing curve for a given integral.
