Howard Crosby Butler was an American archaeologist. Butler graduated from Princeton University, and later pursued special studies at the Columbia School of Architecture and at the American School of Classical Studies in Rome and in Athens. In 1899, 1904, and 1909, he was at the head of archaeological expeditions in Syria. Turkey's unsolicited request that he oversee the excavation of Sardis represented a rare distinction for an American and a Christian. He became professor of the history of architecture at Princeton in 1905. Butler became unwell on August 11, 1922 after returning from Sardis, via Naples. He was admitted to the American Hospital of Paris in Neuilly on August 13 and died that night.
