Sneferu, also spelt as Snefru or Snofru (in Greek known as Soris), was the founder of the Fourth dynasty of Egypt, reigning from around 2613 BC to 2589 BC.

The father of Egypt's most famous pyramid builder, Khufu, Sneferu was actually more prolific than his heir, being responsible first for completing his father Huni's pyramid at Meidum, then building his own step pyramid there. These were followed by the famous Bent Pyramid at Dahshur, and finally, Egypt's first true pyramid, the Red Pyramid. A small pyramid at Seila, near Meidum, is also believed to have been built at his command.

Sneferu was known to be a wise and just ruler.
