Adam Adamandy Kochański

Adam Adamandy Kochański (5 August 1631 – 17 May 1700) was a Polish mathematician, physicist, clock-maker, pedagogue and librarian. He was the Court Mathematician of John III Sobieski.

Kochański cooperated and corresponded with many scientists, Johannes Hevelius and Gottfried Leibniz among them. He was apparently the only one of the contemporary Poles to know elements of the newly invented calculus. As a mechanic he was a renowned clock maker. He suggested replacing the clock's pendulum with a spring, and standardizing the number of escapements per hour.

He died in Teplice in Bohemia.
