2. Eulerfs work
He also had private tutorials in mathematics from Johann
Bernoulli (1667?1748), who was Professor ofMathematics at the University of Basel.
Johann recognized Eulerfs mathematical gift and convinced his family to let him
switch to mathematics. Euler was excellent at computation and had an essentially
photographic memory. He had great persistence and returned over and over again
to problems that challenged him.
