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.
