author
Best known today for a single surviving work, he wrote in the middle of a sharp 19th-century religious debate. His book takes the form of a lively exchange of letters, making theological argument feel unexpectedly direct and personal.
Henry Waller is a little-documented 19th-century author whose name is chiefly preserved through The Jesuits. Project Gutenberg lists that work under his name, and describes it as a correspondence with Rev. Edward Hoare about a lecture on the Jesuit order, based on an 1852 edition.
What makes Waller interesting is the form of the book as much as the subject. Rather than a detached treatise, it unfolds as a back-and-forth argument over doctrine, morality, and authority, giving readers a window into the religious controversies of Victorian Britain.
Because reliable biographical information about him is scarce in the sources I could confirm, it is safest to remember him through that surviving work: a focused, combative, and very human piece of religious controversy writing.
