Euclid. a Hellenistic scholar living in Egypt in the 3rd Centiry BC.\n\nHis magnum opus was Elements, which wikipaedia summarise as follows:\n\nAlthough Elements is a geometric work, it also includes results that today would be classified as number theory. The contents of the work are as follows:\n\nBooks 1 through 4 deal with plane geometry:\n\nBook 1 contains the basic properties of geometry: the Pythagorean theorem, equality of angles and areas, parallelism, the sum of the angles in a triangle, and the three cases in which triangles are "equal" (have the same area).\n\nBook 2 is commonly called the "book of geometrical algebra," because the material it contains may easily be interpreted as algebra.\n\nBook 3 deals with circles and their properties: inscribed angles, tangents, the power of a point.\n\nBook 4 is concerned with inscribing and circumscribing triangles and regular polygons.\n\nBooks 5 through 10 introduce ratios and proportions:\n\nBook 5 is a treatise on proportions of magnitudes.\n\nBook 6 applies proportions to geometry: Thales' theorem, similar figures.\n\nBook 7 deals strictly with number theory: divisibility, prime numbers, greatest common divisor, least common multiple.\n\nBook 8 deals with proportions in number theory and geometric sequences.\n\nBook 9 applies the results of the preceding two books: the infinitude of prime numbers, the sum of a geometric series, perfect numbers.\n\nBook 10 attempts to classify incommensurable (in modern language, irrational) magnitudes by using the method of exhaustion, a precursor to integration.\n\nBooks 11 through 13 deal with spatial geometry:\n\nBook 11 generalizes the results of Books 1–6 to space: perpendicularity, parallelism, volumes of parallelepipeds.\n\nBook 12 calculates areas and volumes by using the method of exhaustion: cones, pyramids, cylinders, and the sphere.\n\nBook 13 generalizes Book 4 to space: golden section, the five regular (or Platonic) solids inscribed in a sphere

You've gotta put Euler on your list; he's one of the most prolific mathematicians EVER.  Archimedes is probably the best ancient mathematician.  (Pythagoras may be famous for his theorem, but that theorem was known to the Chinese before Pythagoras' time.)  For a name that's been passed down through the ages, though, you've gotta go with al-Khowarizmi.  While he wasn't an innovator, his classic text "al-Jabr wa'l Muqabala" gave us the term "algebra" and his name is the basis of our word "algorithm".

René Descartes is regarded as having invented analytic or coordinate geometry in 1637.  I can't find any information on who invented simultaneous equations.  However, the reason for this is clearly because they are much more ancient than Cartesian geometry.  The Indian mathematician Baudhayana was solving simultaneous equations as early as 800 BCE!  It is true that simultaneous equations have a relationship with coordinate geometry, because a system of equations is solved by a point that is the intersection of the curves represented by the equations.  However, this aspect of simultaneous equations is not fundamental to solving them.

Leonardo Fibonacci was born in Pisa, Italy, around 1175. His father was Guilielmo Bonacci, a secretary of the Republic of Pisa.His father was also a customs officer for the North African city of Bugia. Some time after 1192. Bonacci brought his son with him to Bugia.Guilielmo wanted for Leonardo to become a merchant and so arranged for his instruction in calculational techniques, escpecially those involving the Hindu - Arabic numerals which had not yet been introduced into Europe.Since Fibonacci was the son of a merchant, he was able go travel freely all over the Byzantine Empire. Merchants at the time were immuned, so they were allowed to move about freely. This allowed him to visit many of the area's centers of trade. While he was there, he was able to learn both the mathematics of the scholars and the calculating schemes in popular use, at the time.

erathostenes did it by measuring the angle of a shadow from a stick on a certain day, and then doing it again the next year farther south.  He used geometry to figure out the size of the earth, and wasnot correct, but not too far off.

Euclid (also referred to as Euclid of Alexandria) (Greek: Εὐκλείδης) (c. 325–c. 265 BC), a Greek mathematician, who lived in Alexandria, Hellenistic Egypt, almost certainly during the reign of Ptolemy I (323 BC–283 BC), is often considered to be the "father of geometry". His most popular work, Elements, is thought to be one of the most successful textbooks in the history of mathematics. Within it, the properties of geometrical objects are deduced from a small set of axioms, thereby founding the axiomatic method of mathematics.\n\nAlthough best-known for its geometric results, the Elements also includes various results in number theory, such as the connection between perfect numbers and Mersenne primes, the proof of the infinitude of prime numbers, Euclid's lemma on factorization (which lead to the fundamental theorem of arithmetic, on uniqueness of prime factorizations), and the Euclidean algorithm for finding the greatest common divisor of two numbers.\n\nEuclid also wrote works on perspective, conic sections, spherical geometry, and possibly quadric surfaces. Neither the year nor place of his birth have been established, nor the circumstances of his death.\nIn geometry, the parallel postulate, also called Euclid's fifth postulate since it is the fifth postulate in Euclid's Elements, is a distinctive axiom in what is now called Euclidean geometry. It states that:\n\nIf a line segment intersects two straight lines forming two interior angles on the same side that sum to less than two right angles, then the two lines, if extended indefinitely, meet on that side on which the angles sum to less than two right angles.\n\nEuclidean geometry is the study of geometry that satisfies all of Euclid's axioms, including the parallel postulate. A geometry where the parallel postulate cannot hold is known as a non-euclidean geometry. Geometry that is independent of Euclid's fifth postulate (i.e., only assumes the first four postulates) is known as absolute geometry (or, in some places, neutral geometry).

The theorem (that every real integer can be written as the sum of four squares) was first stated (or enunciated) by Diophatus, the "father of algebra", around 1,800 years ago.  It may have been solved by Pierre de Fermet in 1638, but the first known, published proof was that of Joseph Lagrange in 1770.

The sphericity of the earth was known long before Eratosthenes, but he did measure the size of the earth. \n\nEratosthenes had heard tales from travellers that at noon on midsummer's day in Aswan, Egypt, one could see the image of the Sun on the water at the bottom of a deep well. He realized that this could only happen if the Sun was directly vertical on that day at Aswan. He then measured the angle of the Sun from vertical at his home in Alexandria at noon on midsummer's day, and determined (using a compass) that the angle was 1/51 of a full circle. Since he also knew that the distance from Aswan to Alexandria was 5000 stadia (about 500 miles), he computed the circumfrence of the Earth to be 51 * 5000 or 255,000 stadia. This is a remarkably accurate result.

Pythagoras (of Samos, born about 569-82 BC - died about 507 BC) was a Greek philosopher who made important developments in mathematics, astronomy, and the theory of music. The theorem now known as Pythagoras's theorem was known to the Babylonians 1000 years earlier but he may have been the first to prove it. \n\nIn any right triangle, the area of the square whose side is the hypotenuse (the long side of a right triangle opposite the right angle) is equal to the sum of areas of the squares whose sides are the two legs (i.e. the two sides other than the hypotenuse, the adjacent and opposite in sine, cosine and tangent workings). \n\nIf we let c be the length of the hypotenuse and a and b be the lengths of the other two sides, the theorem can be expressed as the equation\n\nThis equation provides a simple relation among the three sides of a right triangle so that if the lengths of any two sides are known, the length of the third side can be found.\n\nI was taught this in a long jumpo sand pit, with 25 billard balls.\nmy old teacher, Mr Chadwick, made a line of 5 balls, and this was the hypotenuse. he then drew in the rest of the triangle. he squared the 5 balls, by making a square of 5 by 5 balls, (25 in all).\n\nthen he put balls on the other lines. three fitted onto the short side, and four onto the next side. he then squared the two other sides. 3 x3 and 4 x 4 (9 and 16, when added together = 25. \n\nhe showed me that 27 years ago, It was amazing, and the reason I am now a teacher.

I think it was Rene Descartes who said "I think so therefore I am."  Whatta guy, not only a philosopher, but he developed the Cartesian coordinate system--y'know, used for graphing equations and functions using the x- and y-axes.

A sicily born mathematician/physicist.\n\nArchimedes (Greek: Αρχιμήδης ) (c. 287 BC–212 BC) was an ancient Sicilian mathematician, physicist, engineer, astronomer and philosopher born in the seaport colony of Syracuse. He is considered by some historians of mathematics to be one of the greatest mathematicians in antiquity; Carl Friedrich Gauss considered him one of the two greatest ever.\n\nWell known for proposing Archimedes principle related to relative density of object and floatation. When he found the truth about relative density.. it is said that, he ran out of the bath yelling at the top of his voice -- "Eureka, eurteka" -- meaning I found it i found it.
