Gemeinhaus-Lewis David De Schweinitz Residence
Also known as: Moravian Museum

Why it's listed
Built in 1733 as a two and a half story log building with white oak boarding, the Gemeinhaus in Bethlehem, Pennsylvania, is the oldest surviving structure in the town and has been owned by the Moravian Church since it was built. By 1743 it measured 94 by 32 feet and contained a chapel, twelve rooms and two dormitories. It was long a residence for Moravian church officials and their families and today operates as a museum. Botanist Lewis David de Schweinitz was born there in 1780 and returned to live there in 1822 after periods in Salem, North Carolina, and Europe. He remained in the house until his death in 1834. His major work, A Synopsis of North American Fungi, classified over 3,000 species, about 1,200 of them his own discoveries. The building is valued as a rare survival of German-Moravian architecture in America and for its link to early American natural history.
Significance in brief: The nomination argues the building is the oldest structure still standing in Bethlehem and an excellent example of German-Moravian architecture in America. It is also significant as the birthplace and home of botanist and mycologist Lewis David de Schweinitz, who is described as one of the leading American botanists and the leading mycologist of his period.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
