Sneferu

Sneferu (also read Snefru or Snofru), well known under his Hellenized name Soris (by Manetho), was the founder of the 4th dynasty during the Old Kingdom. Estimates of his reign vary, with for instance The Oxford History of Ancient Egypt suggesting a reign from around 2613 BC to 2589 BC, a reign of 24 years, while Rolf Krauss suggests a 30-year reign, and Stadelmann a 48-year reign. He built at least three famous pyramids that survive to this day and introduced major innovations in the design and construction of pyramids in Ancient Egypt.
