Sunbury ( SUN-berr-ee), Pennsylvania, is a city that serves as the county seat of Northumberland County. Nestled in the heart of Central Pennsylvania's picturesque Susquehanna Valley, Sunbury is strategically positioned on the east bank of the Susquehanna River. This location is notably downstream from where the river's main and west branches converge, adding to the city's scenic beauty and historical significance.
Sunbury's roots stretch back to the early 18th century, reflecting a rich tapestry of American history. As of the 2010 census, it had a population of 9,905, illustrating its role as a significant community within the region. The city is not only the principal city of the Sunbury, PA Micropolitan Statistical Area but also plays a key role as one of the three principal cities in the larger Bloomsburg-Berwick-Sunbury, PA Combined Statistical Area.
One of Sunbury's most notable historical highlights is its connection to the legendary inventor Thomas Edison. In 1883, the Hotel Edison became the first building in Sunbury to be illuminated by Edison's innovative three-wire electrical system. This event was so momentous that the hotel was later named in honor of Edison. The historical significance of this moment is further accentuated by the story of John W. Treadwell, Jr., a nine-year-old boy who had the honor of flipping the switch to activate the new lights, marking a new era in the city's development.Beyond its electrical history, Sunbury is home to several other historic landmarks. These include the Beck House and the Northumberland County Courthouse, both of which are steeped in architectural and historical value.
