Helen Louise Taft, known as Nellie, was the First Lady of the United States from 1909 to 1913 as the wife of President William Howard Taft. Born to a politically well-connected Ohio family, she took an early interest in political life, deciding at the age of 17 that she wished to become first lady. Herron married Taft in 1886, and she guided him throughout his political career, encouraging him to take actions that would bring him closer to the presidency. Accompanying her husband to the Philippines in 1900, she became a prominent socialite in Manila, contributing to US-Philippines relations. After her husband was appointed Secretary of War, she played a significant role in convincing him to run for president in the 1908 presidential election and making the necessary connections to ensure his success.
