The Journalists Memorial lists all journalists who died (natural causes or murdered) as a result of their work. To the right, which you can faintly make out in the full-size image, are pictures of many of them, plus descriptions of everyone killed in the last year and why.
Incidentally, I wonder why there are so few before, say, 1950: were there fewer journalists back then or do we simply have less information about the ones who were killed and why?
