Euclid wrote the classical book 'The Elements', a collection of geometrical theorems which became a standard work for over 2000 years.

Euclid lived in Alexandria where he founded the first school of mathematics. 'The Elements' consist of 13 books containing chapters on geometrical algebra and number theory.

Euclid proved the number of primes, numbers which are divisible only by themselves and one, to be infinite. He also wrote books on conic sections and optics.
