High Quality Content by WIKIPEDIA articles! Ferdinand Georg Frobenius (October 26, 1849 August 3, 1917) was a German mathematician, best-known for his contributions to the theory of differential equations and to group theory. He also gave the first full proof for the Cayley Hamilton theorem. Frobenius was born in Charlottenburg, a suburb of Berlin, and was educated at the University of Berlin. His thesis, supervised by Weierstrass, was on the solution of differential equations. After its completion in 1870, he taught in Berlin for a few years before receiving an appointment at the Polytechnicum in Zurich (now ETH Zurich). In 1893 he returned to Berlin, where he was elected to the Prussian Academy of Sciences.
