About Frank Whittle:
Air Commodore Sir Frank Whittle is credited with single-handedly inventing the turbojet engine. A patent was submitted by Maxime Guillaume in 1921 for a similar invention; however, this was technically unfeasible at the time. Whittle's jet engines were developed some years earlier than those of Germany's Dr. Hans von Ohain who was the designer of the first jet engine to be used to actually power an aircraft.
