I tried googling this, but I couldn't find it. What is the name of the journalist (who was either British or American...I can't remember) who snuck into Saudi Arabia in the early twentieth century and disguised himself as a Muslim since no non-Muslims were allowed in Saudi Arabia at that time? He wore a turban and brought his wife with him.

T.H. Lawrence (of Arabia). Peter O'Toole depicted in him on the silver screen. Circa the First World War.
