Hetepheres (𓊵𓏏𓊪𓏏𓆑𓂋𓏤𓋴) was the Egyptian queen mother of the 4th Dynasty (c. 2600 BCE) — wife of Pharaoh Sneferu and **mother of Pharaoh Khufu**, who built the Great Pyramid of Giza. Her elaborate burial cache was discovered in 1925 near her son's pyramid.
Her name means "satisfied is Horus."
Hetepheres reduces to nine — the number of Egyptian queen-mother.
