Sergey Kitaev just shared with me an article he wrote with Anthony Mendes in Jeff Remmel's memory. Jeff Remmel was a distinguished mathematician with a very successful career in both logic and combinatorics.
The short biography at the start of the article paints a vivid picture of Jeff Remmel's personality, and will be of interest and inspiration to many readers. His hiring as "an Assistant Professor in the Department of Mathematics at UC San Diego at age 25, without officially finishing his Ph.D. and without having published a single paper" was, in Jeff Remmel's own words, a "fluke that will never happen again."
I had the pleasure of making Jeff Remmel's acquaintance when he visited Sergey in Reykjavik and thoroughly enjoyed talking to him about a variety of subjects. He was truly a larger-than-life academic.
