Pythagoras was an Ionian Greek philosopher, mathematician, and scientist. He is best known for the mathematical Pythagorean theorem. It is said that he was the first man to call himself a philosopher, and he greatly influenced Plato (and therefore Western philosophy).
Euclid was a Greek mathematician best known for his treatise on geometry: The Elements . This influenced the development of Western mathematics for more than 2000 years.
Pythagoras was well known for the Pythagorean Theorem.
Pythagoras was an Ionic Greek Philosopher who went on to create the religious movement Pythagoreanism. Pythagorus is known as a mystic, mathematician, and scientist who is best known for Pythagorean theorem. This theorem is used in mathematics, which says that in any right triangle (a triangle with a right angle opposite a hypotenuse) the sides of the two legs (sides "a" and "b") squared and added together will equal the length of the hypotenuse squared, thus: a^2+b^2=c^2 (^meaning power, or "a-squared+b-squared=c-squared).
Benoit Mandelbrot
Famed as a philosopher and mathematician, his greatest contribution is believed to be the Pythagorean theorem. According to this geometrical theorem, the summation of squares of two sides of a right angle triangle is equals to the square of the hypotenuse side.

Pythagoras was a Greek mathematician and philosopher who lived in the 6th century BC and is best remembered for the Pythagorean theorem (the square of the hypotenuse of a right triangle is equal to the sum of the squares of the opposite two sides). Euclid was a Greek mathematician living in the 4th century BC who taught at the university in Alexandria, Egypt. He became known as the Father of Geometry many years after publishing a thirteen volume work called Euclid's Elements in which he compiled and explained all the known mathematics of his time. Euclid's Elements is the world's most famous mathematical work and is also the oldest continuously used mathematical textbook. It is the foundation of the geometry still being taught in schools almost two and one-half millennium after Euclid's death.
To school children in the Western world, Pythagoras is probably best known for Pythagoras theorem. However, apart from Eurocentrism, there is little to connect Pythagoras with the theorem since it was known to Mesopotemian, Chinese and Indian mathematicians for centuries before Pythagoras.
Robert Arnott Wilson is best known for his work on classifying the maximal subgroups of finite simple groups and for the work in the Monster group.
