After President Woodrow Wilson suffers a debilitating stroke in 1919, First Lady Edith Wilson assumes many day-to-day responsibilities of the presidency. With little formal education, she managed access to the president and oversaw executive functions during a fragile post–World War I moment. Though her authority became widely recognized in Washington at the time, her legacy as “First Woman President” is now largely forgotten. Drawing on his book Madam President William Hazelgrove offers a vivid portrait of the woman who effectively leads the nation during a critical period.
