Lacau oversaw the discovery of the tomb of Tutankhamun in 1922 by the English archaeologists Howard Carter and Lord Carnarvon in the Valley of the Kings. Relations with Carter were rarely cordial and were exacerbated by both the monopoly of publication rights which Lord Carnarvon sold to The Times, and pressure from the Egyptian government who resented the lack of Egyptian involvement in the Tutankhamen excavation.[4]
