Dayton hosts significant research and development in fields like industrial, aeronautical, and engineering that have led to many technological innovations. Much of this innovation is due in part to Wright-Patterson Air Force Base. Dayton is also noted for its association with aviation; the city is home to the National Museum of the United States Airforce and is the birthplace of Orville Wright. Healthcare accounts for much of the Dayton area’s economy. Companies such as Reynolds and Reynolds, CareSource, DPL, LexisNexis, Kettering Health Network, Premier Health Partners, and Standard Register have their headquarters in Dayton.
