Jakob Hermann (16 July 1678 - 11 July 1733) was a mathematician who worked on problems in classical mechanics. He appears to have been the first to show that the Laplace-Runge-Lenz vector is a constant of motion for particles acted upon by an inverse-square central force. Hermann received his initial training from Jacob Bernoulli and graduated with a degree in 1695. He became a member of the Berlin Academy in 1701. Wikipedia
The claim in the paper that credit for the principle should go to Leibniz was based on a letter supposedly written in French by Leibniz to Hermann and quoted in Knig 's paper. www-history.mcs.st-andrews.ac.uk/history/HistTopics/Forge...
