Born in 1866 and identified in library records as Frank H. Hall, or Frank Henry Hall, he appears to have built a career around clear, useful writing rather than literary fame. Catalog and book records connect him with a long list of nonfiction works, including arithmetic textbooks and reference-style volumes such as History of the State of Colorado.
Other surviving records place him at the New York Agricultural Experiment Station in Geneva, where he served as editor and librarian. Publications associated with that work include practical bulletins on topics such as birds in agriculture, dairy bacteriology, poultry nutrition, and vegetable crops, suggesting a writer deeply involved in agricultural education and public information.
Frank Henry Hall died in 1929. Reliable biographical detail beyond his work and dates is limited in the sources I could confirm, so the picture that remains is of a prolific, service-minded author whose books were meant to teach, explain, and be used.
