What’s Happening at HSDC?

The Cameron Solariium with its unrestored19th century wallpaper.Please help us to restore the historic Zuber wallpapers in Simon Cameron’s famous solarium! 

Added to the old Harris Mansion by Simon Cameron, entrepreneur and politician, after he bought the house in 1863, the solarium or sun room boasts some fascinating 19th century wallpapers made by the famous Zuber & Company of France. Still present in their original location, the papers now need a restoration to bring back their beauty and ensure their existence for future generations.

It is said that this room was Cameron’s spot of choice for breakfast. From here he could look out at the rose garden and other gardens around the house where he oversaw the planting of native varieties.

Can’t you imagine him and his family seated in the elegant little room, reading a newspaper over a cup of coffee or tea, feeling the warmth of the morning sun?

The marble floor was restored last year in a project that included repairs and replacement of foundation, joists, and subfloor, as well as the spectacular Italian marble tiles. No more stick-on tiles that were to be temporary but lasted for years!

Please read more about the wallpaper restoration project and  what you can do to help with all the details here.

The Historical Society of Dauphin County (HSDC) was founded in 1869 at Harrisburg, Pennsylvania, the capital city of the Commonwealth of Pennsylvania. Early programs and displays were offered in the 1860 County Courthouse. In 1906, a prominent Harrisburg family donated its Front Street home to the Society as its headquarters. Here the Society remained until 1941, when the heirs of 19th century businessman and politician Simon Cameron gave to the Society their home, built by early settler John Harris, one of the city’s founders.

The mission of the HSDC is to collect, preserve, exhibit, publish, and promote interest in the history of Dauphin County for the education, enjoyment, and benefit of the public.

John Harris-Simon Cameron Mansion

The GeMansion todayorgian-style vernacular stone house was built c. 1766 by John Harris, Jr., whose father was an early settler in the region. Both father and son were tavern-keepers, traders, and ferry operators. The house passed out of the Harris family in the early 19th century, when it served as a home for a distinguished citizen of the city and later has the Pennsylvania Female College. In 1863, Simon Cameron, Lincoln’s first Secretary of War and former Ambassador to Russia, purchased the house and transformed it into the Victorian home we see today. The house is a National Historic Landmark and is used for public and private events, programs, tours, and exhibitions of collections (which number approximately 15,000 items). In recent years nearly $500,000 has been raised and expended on extensive exterior (and some interior) restoration. In 2016 the 250th anniversary of the house was celebrated through numerous programs and events centering on the settlement known as Harris’ Ferry.
