He did research in the area of the arithmetic-geometric mean, continuing work by Gauss and Lagrange. He generalised the results of Kummer on diagonalising symmetric matrices, using determinants and Sturm functions. He was also an editor of Crelle's Journal from 1856 to 1880, during which time it was known as Borchardt's Journal.
