The record — long form
Roberson Mansion is the gift that came with a ghost. Alonzo Roberson — the lumber president and banker — built the Italian Renaissance Revival mansion on Front Street in 1907, childless and past forty, and wrote the city's future into his will: after Margaret's death, the house would become an educational center for everyone. When she died in 1934 the Roberson Memorial Center opened, and the mansion became the museum Binghamton still runs — galleries, planetarium, the Gilded Age rooms intact.
The ghost is the donor himself — staff and visitors report the older gentleman in the halls, seated in the theater, peering from the top-floor windows after closing. The signature encounter is the throat-clearing: employees working late hear a man clear his throat from the first floor when everyone else has gone, the museum's interpretation being Alonzo's polite way of saying it's time to leave. The 2019 staff decorating incident — the whole family hearing it at once — is the register's most cited.
The file keeps the generosity inside the haunting — the mansion was willed to the public, and the ghost is the public's benefactor still checking the house. PBS made the documentary 'Alonzo's Ghost'; the museum runs the haunted tours itself. The Robersons' childlessness built the museum; their continued presence is the staff's running explanation for why the house never quite feels empty.
Roberson Mansion is the archive's benefactor file — the 1907 Italian Renaissance mansion willed to Binghamton as a museum, haunted by the throat-clearing Alonzo who still tells the staff when to go home.
Why this file matters
Roberson Mansion is the archive's bequest file — the Gilded Age mansion its owner gave to the city, the museum where the donor's ghost reportedly still patrols the halls, the philanthropy that made the haunting possible.
A mansion willed to the public keeps its donor — the file's suggestion being that Roberson's hold is Alonzo himself: the man who gave his house to everyone, the throat-clearing that says the museum is closed, and the ghost who never quite gave up the house he gave away.
The Roberson Mansion, part of the Roberson Museum and Science Center, is a home in Binghamton, New York. It is an Italian Renaissance style house, designed by Binghamton architect C. Edward Vosbury and built in 1904, and completed in 1907, for Alonzo Roberson Jr. and his wife Margaret Hays Roberson. It was built with all of the then modern conveniences: an elevator, central heat, combination gas and electric lighting, a dumb waiter, an intercom system, and a private bath for each bedroom.
