Jakob Hermann

He is the author of Phoronomia,[2] an early treatise on mechanics in Latin, which has been translated by Ian Bruce in 2015-16.

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.

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. Petersburg in 1724.

In St.Petersburg, he worked closely together with Daniel Bernoulli who succeeded him in his post[5] as he returned to Basel in 1731 to take a chair in ethics and natural law.

[1] Hermann was elected to the Académie Royale des Sciences (Paris) in 1733, the year of his death.
