Langdon Warner (1881–1955) was an American archaeologist and art historian specializing in East Asian art. He was a professor at Harvard and the Curator of Oriental Art at Harvard’s Fogg Museum. He is reputed to be one of the models for Steven Spielberg's Indiana Jones. As an explorer/agent at the turn of the 20th century he studied the Silk Road. He was elected a Fellow of the American Academy of Arts and Sciences in 1927.
Warner graduated from Harvard College in 1903 with a specialty in Buddhist art and an interest in archeology. After several field trips to Asia, he returned to Harvard, where he taught the university's first courses in Japanese and Chinese art. The Smithsonian Institution sent him to Asia in 1913, and he spent more than a year there, but World War I interrupted his work. In 1922 the Fogg Museum again sent him to China. 
Frescoes at Dunhuang and controversy over the removal of antiquities
Langdon Warner's work in China is the subject of much controversy among art historians. On the one side, there are those who say that he pillaged sites in Asia of their art, in particular frescos from the Mogao caves at Dunhuang. In 1922, the Fogg Museum sent Warner to China to explore western China.  He arrived at the Mogao Caves in Dunhuang in January 1924 and, armed with a special chemical solution for detaching wall-paintings, he removed twenty-six Tang dynasty masterpieces from caves 335, 321, 323 & 320. Warner first applied the chemical solution (strong glue) to the painting on the cave wall. He then place a cloth against it. The cloth is then pulled away from the fresco and then he applied plaster of Paris on the back of the painting and transfer the painting to the plaster surface. Warner had found evidence that the caves were the object of vandalism by Russian soldiers and reached an agreement with the local people to purchase the frescoes and remove them in order to save them for posterity. Unfortunately, the removal process resulted in some damage to the site itself. Luckily, frescoes he framed with glue but was unable to remove are still on display in caves today. Out of 26, only five(5) of the fragments of the murals he removed are in good enough condition to be exhibited now in the Harvard Art Museums, Cambridge, Massachusetts.
The views of the Chinese government towards Warner have varied as intensively as the government itself over the last century. In 1931, the National Commission for the Preservation of Antiquities declared that archeological objects could only be taken from the country if there is no one in the country "sufficiently competent or interested in studying or safe-keeping them." Otherwise, the Commission concluded, it is not longer scientific archeology but commercial vandalism." Warner himself viewed his work as a heroic act of preserving art from destruction. He defended taking fragments from the Longmen Grottoes, saying "if we are ever criticized for buying those chips, the love and labor and the dollars we spent on assembling them should silence all criticism. That in itself is more service to the cause of China bigger than anyone else in this country has even made.  It is worth noting though, most of the destruction was done to fill orders placed by western collectors using images provide by the buyers.
Today the caves in Dunhuang are favored as tourist stops to showcase the Chinese view that the Americans pillaged their heritage. Certain members of the family have requested that the Museum return the pieces to Dunhuang. The Museum's position is that since they have a bill of sale indicating that Warner legitimately purchased the artwork they have no obligation to return them. The Warner family acknowledges both points of view on the matter and seeks resolution.
World War II
Warner's archaeological career was interrupted by the United States' entry into World War II and he became part of the Monuments, Fine Arts and Archives (MFAA) Section of the U.S. Army. He was brought on as an advisor to the MFAA Section in Japan from April to September 1946.
He has been given credit by some for advising against firebombing and the use of the atomic bomb on Kyoto, Nara and other ancient cities to protect cultural heritage of Japan. There are monuments erected in Kyoto, Hōryū-ji (outside the western edge of Hōryū-ji temple), and Kamakura (outside Kamakura JR Station) in his honor for this reason. However, Otis Cary has argued that the credit for sparing Japan's cultural heritage sites belongs not to Langdon but to the U.S. Secretary of War, Henry L. Stimson.
