Jacob Bernoulli
1655 – 1705
Linked beam curvature to bending moment.
A Swiss mathematician and the elder of the Bernoulli dynasty, Jacob linked a beam's curvature to its bending moment in the 1690s — the relation that his nephew Daniel and Euler turned into the beam equation.
The beam-deflection tools here descend from his elastica. He also founded much of probability theory and gave us the number e.
