Euclid was the first Greek mathematician to prove that there are infinite number of prime in 350 B.C.

The Pythagoreans use numbers to symbolize objects and nature. They concerned more on how prime numbers relate to ethics and relgions than with their mathematical proeprties.

570 B.C.

Eratosthenes invented a method called the "sieve of Erathosthenes"

Adrien-Marie Legendre, the first mathematician, to conjecture about the growth of the primes and found the best curve that would predict the distribution of primes and an exact formula to count the primes.

Carl Friedrich Gauss estimated the growth rate of primes and studied the "density" of primes at age 15. He used a coin to model the probabily that a number is prime
