Here's a tribute to Ellison at the time of his death on the CGC forum I ran across.

They mention a few comics adaptations of Ellison's work that rank among my favorites.

Such as THE ILLUSTRATED HARLAN ELLISON (1978) with adaptations by Jim Steranko, Tom Sutton, Alredo Alcala, Leo and Diane Dillon, Wm Stout, and Overton Loyd.
And the Earth/Kyben war stories by Ellison from the 1950's, adapted by Ken Steacy in EPIC ILLUSTRATED, later collected in the NIGHT AND THE ENEMY graphic novel, with some new bridging material.

The last of the Earth/Kyben stories adapted was "Demon With a Glass Hand" in a 1986 DC graphic novel by Marshall Rogers (adapting the award-winning Outer Limits episode in comics form). There are a few that remain unadapted.

I'd forgotten that Ellison had collaborated with Roy Thomas on one or more INCREDIBLE HULK stories in the early 1970's.
And some adaptations by Thomas and Conway that Ellison recalled with contempt in his COMICS JOURNAL interview, of "Repent Harleqin" in UNKNOWN WORLDS OF SCIENCE FICTION magazine 3 (adapted by Thomas and Alex Nino) in 1975, and in CHAMBER OF CHILLS 1 "Delusion For A Dragon Slayer" in Oct 1972 (by Conway and Syd Shores).


Ellison's first published work in comics was an EC story "Upheaval" in WEIRD SCIENCE-FANTASY 24, June 1954, that you can see someone posted in a sealed CGC graded comic container, on the case listed as Ellison's first published work. Which it may or may not be, Ellison was still attending Ohio Stae University in 1954.
As I recall Ellison began his career writing short stories in 1956. Ellison had first written the "Upheaval" story for a 1952 s-f fanzine, then re-packaged it and submitted it to EC. Ellison hit the jackpot, as it was not only purchased by EC, but also illustrated by Al Williamson. Ellison also sold the same story in various forms to several other publishers.
The short story version of it, "Mealtime", was eventually published in Ellison's short story collection ELLISON WONDERLAND in 1962.


So while Ellison sporadically worked in comics while having his primary success as a book author and Hollywood screenwriter, it's pretty wild that he got his initial break as a comics fan who got to work professionally in the comics he loved, and then moved up from there.

Another not listed here is Ellison giving a plot idea to Dennis O'Neil to do a story about Batman hunting a Nazi war criminal that wound up as the O'Neil/Adams story "Night of the Reaper" in BATMAN 237, in Dec 1971.
