Final answer:
Charlotte Corday assassinated Jean-Paul Marat in his bathtub, which Jacques-Louis David later depicted in the painting 'The Death of Marat.'
Step-by-step explanation:
Charlotte Corday stabbed Jean-Paul Marat in his bathtub. Marat was a prominent figure in the French Revolution, often associated with the Reign of Terror. He had a chronic skin condition that required him to spend extended periods submerged in his medicinal bath. It was during one of these instances in 1793 that Corday, seeking to put an end to Marat's influence and the ongoing violence, assassinated him. Shortly after the murder, she was arrested and ultimately executed by guillotine. The famous painting 'The Death of Marat' by Jacques-Louis David immortalizes the moment after Marat's assassination, depicting him as a martyr.
