Eliza McCardle Johnson (October 4, 1810 – January 15, 1876) was the first lady of the United States from 1865 to 1869 as the wife of President Andrew Johnson. She also served as the second lady of the United States from March until April 1865 when her husband was vice president. Johnson was relatively inactive as first lady, and she stayed out of public attention for the duration of her husband's presidency. She was the youngest first lady to wed, doing so at the age of 16.

Johnson significantly contributed to her husband's early career, providing him with an education and encouraging him to strengthen his oratory skills and seek office. Johnson did not participate in the social aspects of politics, however, remaining at home while her husband took office. During the American Civil War, she was forced from her home for her family's Unionist loyalties. She was affected by tuberculosis throughout much of her life, and what activity she did choose to undertake was limited due to her health.

Johnson was briefly the second lady of the United States before becoming the first lady, as her husband was vice president until the assassination of Abraham Lincoln. After becoming the first lady, Johnson delegated the role's social duties to her daughter Martha Johnson Patterson. Though she only made two public appearances during her tenure as first lady, Johnson was a strong influence on her husband, and he would consult her regularly for advice. Johnson returned to her home of Greeneville, Tennessee with her family after leaving the White House, living a quiet retirement. She died six months after her husband and was buried beside him.

Early life and marriage

Eliza McCardle was born in Greeneville, Tennessee on October 4, 1810. She was the only child of John McCardle, a cobbler and innkeeper, and Sarah Phillips. McCardle was raised by her widowed mother, who financially supported her by weaving McCardle attended school and received a basic education. She is believed to have attended the Rhea Academy in Greenville.

McCardle met Andrew Johnson when his family moved to Greeneville in September 1826. She is said to have first seen him while talking amongst her friends, who began to tease her when she expressed her interest in the tailor's apprentice. After marrying, the couple moved into a two room house, where one of the rooms served as a tailor shop.

Eliza Johnson provided her husband much of his formal education, She played a large role in his early political career, assisting him in his education and his oratory skill.

Johnson assisted the president with his speeches as she did in his previous political positions, and she worked to prevent the outbursts caused by his temper.

Johnson returned to the practice common among 19th century first ladies in which she allowed a younger surrogate to perform much of her duties, reestablishing the practice after the highly public tenure of her predecessor Mary Todd Lincoln. She would be the last first lady to invoke illness in this fashion until Ida Saxton McKinley much later.
