Wright brothers
After that, they started a company to build airplanes.  They had a patent war with Glenn Curtiss, filing lawsuits against each other over who really invented the airplane steering system.  The Wrights believed that Curtiss' aileron system was too similar to their own steering system and that he had copied them.  During the patent war, Wilbur died.  Orville continued working to keep his reputation as the first man to fly. Later he sold the airplane company and became an elder statesman of aviation. He died in 1948.
