Web7.6. The recursive process was stated rst by Erhard Schmidt (1876-1959) in 1907. The essence of the formula was already in a 1883 paper by J.P.Gram in 1883 which Schmidt mentions in a footnote. The process seems to already have been anticipated by Laplace (1749-1827) and was also used by Cauchy (1789-1857) in 1836. Figure 1. Examples … Webjakevdp commented on Jan 27, 2016.
