The Imaginary Invalid is a three-act comédie-ballet by the French playwright Molière. It was first performed in 1673 and was the last work he wrote. The plot centers around Argan, the 'imaginary invalid' who is completely dependent on his doctors and wants to marry his daughter to a doctor against her will, so that he will always have medical care freely available to him. In an ironic twist of fate, Molière collapsed during his fourth performance as Argan on 17 February and died soon after.
