William Joseph Harding-King was educated at Trinity College, Cambridge. His first journey into the Sahara took place in 1900, after which he published his book In Search of the Masked Tawareks. He returned to the Sahara again in 1908 and then again between 1909 to 1912. His contributions to a number of journals represented a significant contribution of knowledge to desert studies and he was awarded the Gill Memorial Memorial Medal by the Royal Geographical Society in 1919.
