Stephen Harriman Long (December 30, 1784 – September 4, 1864) was an American army civil engineer, explorer, and inventor. As an inventor, he is noted for his developments in the design of steam locomotives. He was also one of the most prolific explorers of the early 1800s, although his career as an explorer was relatively short-lived. He covered over 26,000 miles in five expeditions, including a scientific expedition in the Great Plains area, which he famously confirmed as a "Great Desert" (leading to the term "the Great American Desert").
