Daniel R. Gilgannon

Daniel R. Gilgannon was an American science fiction author whose best-known work is Stopwatch on the World. Reliable bibliographic sources identify him as the author of that novel and list a modest publication record in the field.

Although he is not widely documented in mainstream literary reference sources, his work continues to surface in library and genre databases, which suggests a lasting niche interest among readers of vintage science fiction.

A memorial listing under the full name Daniel Regis Gilgannon appears to match the author, but because detailed biographical information is limited, many personal details about his life are not well confirmed in easily available sources.
