The John W. Jones House currently stands at 1250 Davis Street, Elmira, New York, across from a historic entrance to Woodlawn Cemetery.
 It is the former home of John W. Jones and current home of the John W. Jones Museum.
 It stands on part of its original property, though it originally faced College Avenue.
 Historically, the house was the private residence of John W. Jones and his family, but changed ownership several times since, and was used as rental property that fell into disrepair.
 Condemned by the City of Elmira in 1997, Lucy Brown brought it to the public’s attention and with a group of concerned citizens, saved it from demolition.
 It is now the home to the John W. Jones Museum.

 The prize is named in honor of science fiction editor and writer John W. Campbell, whose science fiction writing and role as editor of "Analog Science Fiction and Fact" made him one of the most influential editors in the early history of science fiction.
