Nicolaus II Bernoulli

He was a friend and contemporary of Leonhard Euler, who studied under Nicolaus' father.

He served as an assistant to his father, among other areas, in the correspondence over the priority dispute between Isaac Newton and Leibniz, and also in the priority dispute between his father and the English mathematician Brook Taylor.

In 1720 he posed the problem of reciprocal orthogonal trajectories, which was intended as a challenge for the English Newtonians.

In 1725 he together with his brother Daniel, with whom he was touring Italy and France at this time, was invited by Peter the Great to the newly founded St. Petersburg Academy.

His professorship was succeeded in 1727 by Leonhard Euler, whom the Bernoulli brothers had recommended.
