Harriet Lane was a capable hostess and a philanthropist, and this month we will share some lesser-known insights about her. Stay tuned as each month we examine a different first lady and their profound impact on the Executive Mansion and beyond.

Upon her death in 1903, Harriet bequeathed a sizable European art collection to the Smithsonian & became known as the 'First Lady of the National Collection of Fine Arts.' She also donated a large sum to endow a home for children at Johns Hopkins Hospital in Baltimore.
