Gram taught at the University of Copenhagen but he was also managing director of an insurance company and chairman of the Danish Insurance Council. In 1874 he published Sur quelques théorèmes fondamentaux de l'algèbre moderne in Mathematische Annalen. Gram is best remembered for the Gram-Schmidt orthogonalisation process which constructs an orthogonal set of from an independent one. He was not however the first to use this method. The process seems to be a result of Laplace and it was essentially used by Cauchy in 1836. References:
