Alan St. H. (Alan St. Hill) Brock

Alan St. H. Brock, also listed as Alan St. Hill Brock, was a British author born in 1886. The clearest source I could confirm for him in this search is bibliographic: Project Gutenberg and the Internet Archive both identify him as the author of Pyrotechnics: The History and Art of Firework Making, first published in 1922.

Library records also connect his name with other books on the same subject, including Fireworks and Fetes and A History of Fireworks. Taken together, those records suggest he devoted much of his writing to explaining fireworks not just as spectacle, but as a technical craft with a long cultural history.

Reliable biographical details about his personal life were limited in the sources I could confirm here, so it seems best to remember him chiefly through his unusual area of expertise: making the world of pyrotechnics understandable and engaging for general readers.
