It was independently discovered by Johann Benedict...

, Roch went to the University of Berlin, where he met Kronecker, Weierstrass and others. In 1862 he was awarded a masters degree from Leipzig and later a doctorate for his work on electromagnetism.

From this point his work took a more mathematical slant. In the following year he published the paper containing the result for which he is famous to this day, the Riemann–Roch theorem
