The correct answer is Hippodamus of Miletus
He was the promoter, if not the inventor, of the urban system of regular mesh that became known as the Hypodamic System. This system consists of the organization of cities through streets arranged in an orthogonal matrix, creating housing blocks between them and in which all public and religious buildings or squares fit into this mesh. It is thought to have been used for the first time in the reconstruction of Miletus in 479 BCE after its destruction by the Persians.
