Aeschylus:
A Greek playwright back in 500 BC. Many historians consider him the father of Greek tragedies.
How he died: An eagle dropped a tortoise on his head
According to legend, eagles picked up tortoises and attempt to crack them open by dropping them on rocks. An eagle mistook Aeschylus' head for a rock (he was bald) and dropped it on him instead.

Tycho Brahe:
An important Danish astronomer of the 16th century. His ground breaking research allowed Sir Isaac Newton to come up with the theory of gravity.
How he died: Didn't get to the bathroom in time.
In the 16th century, it was considered an insult to leave a banquet table before the meal was over. Brahe, known to drink excessively, had a bladder condition-but failed to relieve himself before the banquet started. He made matters worse by drinking too much at dinner, and was too polite to ask to be excused. His bladder finally burst, killing him slowly and painfully over the next 11 days.
