1654-1705


Bernoulli was the family name of three Swiss mathematicians, two bothers, Jakob and John, and John's son Daniel.

Jakob Bernoulli worked on the foundation of probability theory, analytic geometry, and the calculus of variations at the University of Basel. He also studied the catenary, the curve formed by a free hanging rope; the logarithmic spiral; and the cycloid, the path of a point on a turning circle.
