June 21, 1810, and June 21, 1940, marked the wedding days of two future U.S. Presidents to their first ladies. Zachary Taylor, who would become the 12th President of the United States, married Margaret Mackall Smith, while Richard Nixon, who would become the 37th President, married Thelma Catherine “Pat” Ryan. These unions not only shaped their personal lives but also their political careers, as both first ladies played significant roles in their husband’s political and public life narratives.
