Jakob Hermann
mathematician from Basel (1678-1733)
Jakob Hermann (16 July 1678 – 11 July 1733) was a mathematician who worked on problems in classical mechanics. He is the author of Phoronomia, an early treatise on mechanics in Latin, which has been translated by Ian Bruce in 2015-16. In 1729, he proclaimed that it was as easy to graph a locus on the polar coordinate system as it was to graph it on the Cartesian coordinate system.
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 was born and died in Basel. He received his mathematical training from Jacob Bernoulli at the University of Basel and graduated with a degree in 1695. In 1696, he obtained a Master's Degree by defending a dissertation on infinite series. Jacob Bernoulli considered Hermann to be the best of his many students at the university and when Jacob Bernoulli died in 1705, Gottfried Leibniz asked Hermann to write an obituary for Bernoulli in Acta Eruditorum. He became a member of the Berlin Academy in 1701. He was appointed to a chair in mathematics in Padua in 1707, but moved to Frankfurt an der Oder in 1713, and thence to St.
The public source identifies “Jakob Hermann” as mathematician from Basel (1678-1733). This brief keeps that definition visible, then builds a research path around Jakob, Hermann and mathematician.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Jakob Hermann”, the useful work is to connect “mathematician from Basel (1678-1733)” to the records capable of establishing context and consequence.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Apr 25, 2025. The linked authority identifier is Q689611. The first chronological checks are 1678, 1733, 2015 and 1729.
A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
