In April of 1919, the president traveled to Europe himself. The war had ended in November. But the spread of the flu continued. And Wilson got sick. The president’s condition deteriorated so quickly and drastically that his personal doctor, Cary T. Grayson, worried that Wilson had been poisoned.
Even as Grayson told reporters that Wilson had a cold, he fretted about the president’s condition. ” I was able to control the spasms of coughing,” Grayson wrote, “but his condition looked very serious.” The president couldn’t even sit up in bed.
Worse, in the midst of fragile negotiations, the president began to act strangely. He acquiesced to French demands that had once seemed impossible; Wilson believed he was surrounded by spies; one colonel noted that the president had lost “his quickness of grasp, and tired easily.”
Wilson did recover. But he suffered a stroke months later that crippled his administration, and set up his wife as a de facto president.
