On the evening of April 3rd, 1919, President Woodrow Wilson, who was in Paris for the Versailles Treaty negotiations, became suddenly and dangerously ill. At first his doctor thought that he’d been poisoned. Wilson had a high fever and bad cough for five days, during which time the same doctor told the outside world that Wilson had a bad cold. When Wilson returned to the conference he was visibly weakened, seemingly exhausted. As time passed at least two lingering after- effects manifested themselves: first, an apparent neurological disorder as Wilson became paranoid in petty ways, suspecting the French of spying on him, and second, likely due to debility, when he returned to the conference he caved in on all of his 14 points then still in contention excepting number XIV (a League of Nations), which Clemenceau and Lloyd George disdained to give him.
