Robert Louis Stevenson lived from 1850 to 1894, so the following poets are candidates for the answer:
William Crowe (1745–1829).
Richard Flecknoe (c. 1600 – 1678).
J. Ingo (lived c. 1800; only one poem, though).
John Bedford Leno (1826 – 1894).
Laurence Minot (1300? – 1352?; contemporaries may have pronounced his name in a way that does not rhyme with ...
After some more searching, I found that the academic and author I was looking for is Frank Lentricchia.
In literary theory and criticism he wrote, among other ones, the following books:
After the New Criticism (University of Chicago Press, 1980), in which he reviews and evaluates the "critical theory" (not just literary theory, since he also discusses the ...
Googling for the exact phrase "merry sums" leads to the book Primrose Day by Carolyn Haywood. The search results page in the book show the girl's teacher explaining to her that they say "examples" instead of "sums" and is quickly followed by a scene in which other kids tease her "Oh, Merry Sums!

"Bolivar cannot carry double."
If that rings a bell, this is likely to be "The Roads We Take" by O. Henry.
Bob Tidball and "Shark" Dodson rob a train, and Bob suggests that they ride together on Dodson's horse, Bolivar, when his horse breaks a leg. But:
"Set still," said Shark. "You ain't goin' to hit no breeze, Bob. I
hate to tell you, but there ain'...

Chapter XXIV of Book I of that work begins as follows (quoted from Wikisource):
A proposal was once made in the Senate to distinguish slaves from free men by their ...

258. Hale: Sir Matthew Hale (1609-76), Chief Justice of the King's Bench, devout Puritan, and able philosophical defender of the Mosaic Account of the creation.

This is conjectural, but just before the passage in question, Camus writes something like
We sail across spaces so vast they seem unending. Sun and moon rise and fall in turn, on the same thread of light and night. Days at sea, as similar each to the other as happiness . . .
which to me echos some (but not all) of this passage in R. L. Stevenson's In the ...
Doesn't look like it.
For each of these (female) authors, the "Porter" in her name was her married name, taken from her husband. So if their shared surname is not a coincidence, it must come from a blood relation between their husbands, not the women themselves.
Eleanor H. Porter (née Eleanor Emily Hodgman, daughter of Francis Fletcher Hodgman and Llewella ...
The most likely candidate is Félix Fénéon (22 June 1861 – 29 February 1944). A collection of his short fiction Novels in Three Lines (Nouvelles en trois lignes in French) was translated by Luc Sante and published in 2007. A review by Julian Barnes appeared in the London Review of Books on 4 October 2007.
