Johann Ludwig (also known as John Lewis, Jean Louis) Burckhardt (Arabic: يوهان لودفيك بركهارت; 24 November 1784 – 15 October 1817) was a Swiss traveller, geographer and Orientalist. Burckhardt assumed the alias Sheikh Ibrahim Ibn Abdallah during his travels in Arabia. He wrote his letters in French and signed Louis. He is best known for rediscovering two of the world's most famous examples of rock-cut architecture – the ruins of the ancient Nabataean city of Petra in Jordan and the temples of Abu Simbel in Egypt.
