What is "khaemweset"

Prince Khaemweset (also translated as Khamwese, Khaemwese or Khaemwaset) was the fourth son of Ramesses II, and the second son by his queen Isetnofret. He is by far the best known son of Ramesses II, and his contributions to Egyptian society were remembered for centuries after his death. Khaemweset has been described as "the first Egyptologist" due to his efforts in identifying and restoring historic buildings, tombs and temples.
