Context: La Razón de mi vida (literal translation: "The Reason for My Life") is the autobiography of Eva Perón, First Lady of Argentina from 1946 until her death in 1952.  Published in 1951 shortly before Eva Perón's death, it became one of the fastest selling books in Argentine history.  Written in a conversational tone, it is largely a compilation of her speeches.  Eva Perón shares her perspectives on feminism and the role of women in political life, labor rights, poverty, and, of course, Peronism, the political movement founded by her husband Juan Perón.  In 1952, the year she died, the Congress of Argentina ordered the autobiography to be used as a textbook in the Argentine schools.

Published in England and the United States shortly after Eva Perón's death, it was the first hostile biography of Eva Perón to be published and, despite the criticism that it is lacking in historical value, has therefore been used by her detractors ever since.  This book is thought to be the basis for the Andrew Lloyd Webber and Tim Rice musical "Evita".  However, the book was never officially credited as such, and Rice incorporated many other historical materials as background. Vicki Risch is the former First Lady of Idaho and the wife of U.S. Sen.

The First Lady of the United States is the hostess of the White House.  The position is traditionally filled by the wife of the President of the United States, but, on occasion, the title has been applied to women who were not presidents’ wives, such as when the president was a bachelor or widower, or when the wife of the president was unable to fulfill the duties of the First Lady herself.  The First Lady is not an elected position; it carries no official duties and receives no salary.  Nonetheless, she attends many official ceremonies and functions of state either along with or in place of the president.  Traditionally, the First Lady does not hold outside employment while occupying the office.  She has her own staff, including the White House Social Secretary, the Chief of Staff, the Press Secretary, the Chief Floral Designer, and the Executive Chef.  The Office of the First Lady is also in charge of all social and ceremonial events of the White House, and is a branch of the Executive Office of the President.
