Confederate Brigadier-General.
Loved science so much that he had a personal astronomical observatory built into his house. According to people who knew Gregg, his science library rivaled that of Harvard University. His day job was being a lawyer.
Proving that science and skepticism aren't necessarily a good defense against bone-headedness - Gregg was also a "fire-eating" Secessionist who helped draft South Carolina's ordinance of session.
At the battle of Fredericksburg in Dec. 1862, Gregg was shot thru the spine and lingered in horrible pain for 2 days before dying.
According to legend, during that 2 days he was badgered to do a deathbed conversion by the religious fanatic "Stonewall" Jackson. Gregg just replied: "You know I'm not a believer."
(That scene was used in the 2003 movie
Gods & Generals, which had a running time damn near as long as the real Civil War.)

"Stonewall" Jackson was one case of religious mania actually doing something good, however unintentional. Jackson fervently believed that every human being needed to read the Bible, so he taught slaves how to read. That was highly illegal in Virginia at the time.
Oh, Flannery O'Connor was a Catholic, and apparently a pretty devout one. Some lit-critics have called her "the greatest Xian writer." Much of the irony and tension in her writing came from her ideas of religion, as opposed to those of her...more fervent Protestant brethren in Georgia.
My usual plug: if you've never seen it, get ahold of John Huston's 1980 film version of "Wise Blood." Huston worked with O'Connor's literary executors and the script is lifted almost verbatim from the book:
"I'm gonna start me a new church. Where the blind don't see, the crippled don't walk, and what's dead stays that way.":rofl:
