Hippodamus of Miletus

Hippodamus of Miletus (/hɪˈpɒdəməs/; Greek: Ἱππόδαμος ὁ Μιλήσιος, Hippodamos ho Milesios; c.480–408 BC) was an ancient Greek architect, urban planner, physician, mathematician, meteorologist and philosopher, who is considered to be "the father of European urban planning", and the namesake of the "Hippodamian plan" (grid plan) of city layout, although rectangular city plans were in use by the ancient Greeks as early as the 8th c. BC.

Hippodamus was born in Miletus and lived during the 5th century BC. His father was Euryphon. According to Aristotle, Hippodamus was the first author who wrote upon the theory of government, without any knowledge of practical affairs.
