Numerous inventions and scientific breakthroughs have occurred in North Carolina. Many inventors are well-known, such as the Wright Brothers, Caleb Bradham, and Richard Gatling. Others may not be widely known for a number of reasons, such as being unable to secure a patent. In 1801, G. F. Saltonstall of Fayetteville was the first North Carolinian to receive a patent. He had invented a new method of processing grain. Davis provides a timeline of North Carolina inventors and their creations from 1801 to 2005.
