Emperdocles used his science skills to solve a water crises in the town of Selinus, a town with active volcanic craters nearby. After this, the townsfolk worshiped him as if he was a God. Eventually this got to his head, and, convinced that he was divine, he jumped into a volcano. Many believe that this is the reason for him not having a grave.
Living in Athens at the time, figs were a delicacy. While Chryssipus was walking home with a plate of figs, he looked down and saw a donkey happily eating away at them. According to sources this was so funny that he laughed himself to death after saying "why don't we give him some fine vintage wine to wash it down".
Diogenes lived most of his life in a big discarded tub. He voluntarily lived as a homeless person, often saying crazy things. Being such a famous figure, there are multiple conflicting accounts of his death. Some believe he tied from trying to eat an octopus raw. Others believe that he voluntarily held his breath in order to escape from life. On the other hand, many believe that he was trying to feed a single octopus to several dogs, but was then bitten on the foot, which ultimately lead to his death.
