Robert Raymond Smith Barry (4 April 1886 – 23 April 1949) was an officer in the Royal Flying Corps and its successor, the Royal Air Force. His most notable contribution was in developing flying instruction methods. In December 1916 he masterminded a complete reorganisation of flying training methods at Gosport. This new training method later became known as the "Gosport System" and was adopted worldwide. Smith-Barry was later described by Lord Trenchard as the man who "taught the air forces of the world how to fly".
