| Notes | In 1914, Roosevelt developed a relationship with Lucy Mercer, his wife’s social secretary, which evolved into a love affair. When Eleanor discovered the affair, she gave Franklin an ultimatum in 1918 to stop seeing Lucy or she would file for divorce. Roosevelt agreed to stop seeing Mercer romantically, but years later began secretly see Mercer again. She was, in fact, with him at the time of his death. |
