author
A little-known early 20th-century writer, he is best remembered today for co-authoring the South African War novel On the Firing Line. His surviving public record is sparse, which gives his work a certain archival curiosity.

by Anna Chapin Ray, Hamilton Brock Fuller
Hamilton Brock Fuller appears in major public-domain book records as a co-author of On the Firing Line, a 1905 novel written with Anna Chapin Ray. His name is listed in library-style sources including Project Gutenberg, Wikisource, and The Online Books Page, which confirm his connection to that book.
Very little biographical information about him is readily documented in the reliable sources available here. Because the record is so limited, it is safest to describe him as an early 20th-century author known primarily through that surviving collaboration rather than to make broader claims about his life or career.
For readers of historical fiction and rediscovered books, his appeal lies in that period context: a writer whose work has outlasted most of the details of his biography.
