Jacob Bernoulli
Jacob Bernoulli (also known as James' or Jacques) (December 27, 1654 – August 16, 1705) was a Swiss mathematician. He mainly contributed to Analytic geometry, Probability theory, Variable calculus. Bernoulli's inequality which is often taught in high schools was named to honor him. Bernoulli, together with Newton and Leibniz, was considered the first ones who developed the Differential calculus and Integral but he researched deeper insights. His book on Probability Theory had not been published until 1713, 8 years after Bernoulli's death. He had a younger brother 12 years younger who was also a famous mathematician Johann Bernoulli. The Bernoulli family later had many talented mathematicians.
