Francis S. (Francis Sales) Betten

Born in 1863 and listed in library records as Francis Sales Betten, S.J., he was a Jesuit priest and author whose work reached across several fields. Surviving catalogs and digital libraries connect him with books on history, religion, and education, including The Roman Index of Forbidden Books (1909) and From Many Centuries: A Collection of Historical Papers (1938).

Betten also appears in the record of early North American entomology through A Handbook of the Dragonflies of North America, a work associated with the Biodiversity Heritage Library and long remembered by later readers of Odonata studies. That mix of subjects gives him an unusual profile: part teacher, part historian, and part naturalist.

He died in 1942. While many fine-grained biographical details are hard to confirm from the sources available here, the books themselves show a writer interested in making specialized knowledge readable for general audiences.
