I came across this rather interesting list this morning. It is the Wiki List_of_Unusual_Deaths. Some of these are pretty good. It's a rather long list of strange facts but here are a few that caught my eye. They are all sorted by year in history.
1327: Edward II of England, after being deposed and imprisoned by his Queen consort Isabella and her lover Roger Mortimer, was rumored to have been murdered by having a red-hot iron inserted into his anus.
1601: Tycho Brahe, according to legend, died of complications resulting from a strained bladder at a banquet. It would have been extremely bad etiquette to leave the table before the meal was finished, so he stayed until he became fatally ill. This version of events has since been brought into question as other causes of death (murder by Johannes Kepler, suicide, and mercury poisoning among others) have come to the fore.
1753: Professor Georg Wilhelm Richmann, of Saint Petersburg, Russia, became the first recorded person to be killed while performing electrical experiments when he was struck and killed by a globe of ball lightning. 
1814: London Beer Flood, 9 people were killed when 323,000 imperial gallons (1 468 000 L) of beer in the Meux and Company Brewery burst out of their vats and gushed into the streets.
1963: Thích Qu?ng ??c, a Vietnamese Buddhist monk, sat down in the middle of a busy intersection in Saigon, covered himself in gasoline, and lit himself on fire, burning himself to death. ??c was protesting President Ngô ?ình Di?m's administration for oppressing the Buddhist religion.
