Hero of Alexandria
Hero (or Heron) of Alexandria (Greek: Ἥρων ὁ Ἀλεξανδρεύς) (c. 10–70 CE) was an ancient Greek mathematician and engineer. He lived and worked in Alexandria when Alexander the Great ruled. He is famous for his numerous contraptions and experiments. His geometrical works deal largely with problems on mensuration written in three books. Book 1 deals with the area of squares, rectangles, triangles, trapezoids,various other specialized quadrilateral , the regular polygons, circles, surfaces of cylinder, cones, spheres etc. Heron has derived the famous formula for the area of a triangle using its three sides.

"At least from the days of Alexander the Great to the close of the classical world, there undoubtedly was much intercommunication between Greece and Mesopotamia, and it seems to be clear that the Babylonian arithmetic and algebraic formulas continued to exert considerable influence in the Hellenistic world. This aspect of mathematics, for example, appears so strongly in Heron of Alexandria (fl. ca. A.D. 100) that Heron once was thought to be Egyptian or Phoenician rather than Greek. Now it is thought that Heron portrays a type of mathematics that had long been present in Greece but does not find a representative among the great figures - except perhaps as betrayed by Ptolemy in the Tetrabiblos."
