Johann Bernoulli

Johann Bernoulli was born 27 July 1667 in Switzerland, into what would become a dynasty of mathematicians bearing his surname. He made his mark advancing infinitesimal calculus, the new mathematics of change and motion. Among his pupils was a young Leonhard Euler, whom he guided early on. He died 1 January 1748, having spent a lifetime in a field his family name had come to define.
