Note: (More than one GM can share credit for a season for any year they were GM for a full or partial part of said season.

One of the things I found from this is that 3 GM’s died while holding the position.
The Atlanta Braves GM Bill Lucas (Died 5/5/1979), The Los Angeles Dodgers GM Fresco Thompson (Promoted 6/4/1968; Died “several months later”) and the one that most surprised me because I don’t recall it ever being mentioned The New York Mets GM Johnny Murphy (Died 1/14/1970).
