Hasan al-Rammah (Arabic: حسن الرماح‎) (died 1295) was a Syrian Arab chemist and engineer during the Mamluk Sultanate who studied gunpowders and explosives, and sketched prototype instruments of warfare, including the first torpedo. Al-Rammah called his early torpedo "an egg which moves itself and burns." It was made of two sheet-pans of metal fastened together and filled with naptha, metal filings, and saltpeter. It was intended to move across the surface of the water, propelled by a large rocket and kept on course by a small rudder.
