Mathematician:Johann Bernoulli

Swiss mathematician (also known as Jean or John) best known for his work on development of the calculus.

Pioneered the technique of Integration by Parts.

Younger brother of Jacob Bernoulli, with whom he did not always see eye to eye. Posed the Brachistochrone Problem: to find the curve down which a particle will take the shortest possible time between two points. This was solved by Jacob Bernoulli.
