A mid-century science-fiction writer whose work blends big global stakes with brisk, imaginative storytelling. Best known for Stopwatch on the World, he also led a life of teaching, service, and wartime reporting.

by Daniel R. Gilgannon
Daniel R. Gilgannon was an American writer remembered today for Stopwatch on the World, a science-fiction novel first published in the early 1950s and later made widely available through Project Gutenberg. The book imagines a world under extraordinary pressure, showing his taste for high-concept ideas and urgent, suspenseful plots.
Beyond his fiction, Gilgannon appears to have lived a notably service-minded life. Memorial records describe him as a former teacher and principal in New York, with work at Delehanty High School in Jamaica and St. Agnes Cathedral High School in Rockville Centre. They also note that he reported for Stars and Stripes during World War II.
He was born in 1916 and died in 2009. While detailed literary biographical information is limited, the available records suggest a writer whose imagination sat alongside a long commitment to education, community, and public service.
