Presidents and First Ladies Trivia

[Anita]

After reading many of the biographies of First Ladies, I was surprised how many were afflicted with serious medical conditions. Many were suffering with these conditions while in the White House. Laurie's post on Ida McKinley is a good example. http://www.firstladies.org/biographies

Name the First Lady who was so ill she and her husband had to remain in the White for weeks after her husband's term expired?
