J.A. Konrath is a self-publishing champion in terms of putting his works out on his own imprint and encouraging others to do so, but is also actually a traditionally-published backlist author, as you can see via his Stop You're Killing Me website bibliography listing, which shows that his Jack Daniels mystery series (of which we're getting a related short story collection as one of the current freebies; they may be self-published instead of having first been printed in various mystery magazines (I didn't really check for that since it's a repeat), but they're tie-ins to a popular print series) is a multiple nominee for the Macavity, Anthony, and Barry awards, with the 1st novel originally published by Disney's Hyperion imprint.
I'm surprised you don't recognize his name, as he's shown up in News and General Discussions many times over the years for his views on authors self-publishing their backlists instead of re-signing with the traditional publishers again for the e-book re-releases, including some of the current discussions on that Author's Guild letter thing.
Anyway, here's his
Wikipedia entry, and some sample dedicated discussion threads here on MR from a few years ago:
Joe Konrath on copyright and fair use,
Konrath and friends take on Turow,
LA Times: Joe Konrath can't wait for his books to go out of print.
ETA: Wikipedia says that he's had Jack Daniels shorts published in Ellery Queen's Mystery Magazine and other traditional print outlets.
