As office and residence of the president of the United States, the White House is uniquely tied to both the life of the nation and the private lives of the building's occupants. Americans have approached its grounds for celebrations and demonstrations, for Easter Egg Rolls and the right to vote. Citizens have looked to the White House for leadership during times of the gravest national import, yet also to share in the joys and sorrows experienced by the families living there. The White House has undergone many changes through the years-some by blueprint, some by chance. Yet the building has always stood solid, each alteration becoming a part of its life experience. Historic Photos of the White House contains nearly 200 images taken between the years 1846 and 1977. They show scenes of presidential business, intimate family moments, public interaction, and various changes to the White House itself. Together, these images provide a fascinating view through history of an institution described as "the most famous and highly cherished building in the whole country."
