[Cavalry and the crowds at the St. Louis world's fair]

The Louisiana Purchase Exposition, commonly known as the Saint Louis World's Fair of 1904, was the last great international exposition before World War I. The fair, built on a 1,200 acre site, included hundreds of thousands of objects, people, animals, displays, and publications from 62 exhibiting countries and 43 of the 45 states. The setting of world records, such as the largest organ, and working displays of every important technological advance were significant design goals. The Fair was a combination of trade show, civic showpiece, and monument to culture, along with more than a tinge of American pride. The Fair showcased the grandiose ambition of the gilded age, forming a kind of collective tribute to the nineteenth century's international understanding of the furtherance of peace, prosperity, and progress. It's a grand snapshot in time of American and foreign societies as they wished to portray themselves.

Frances Benjamin Johnston (1864-1952) was an American photographer who is best known for her pioneering work in the field of architectural and landscape photography. She was born in Grafton, West Virginia, and after studying art and photography in Paris, she returned to the United States and established herself as a successful photographer. Johnston's work focused primarily on architecture, and she photographed many of the most significant buildings and structures of her time. She also photographed landscapes, gardens, and people, and her work often appeared in magazines such as House Beautiful, Ladies' Home Journal, and Country Life. One of Johnston's most notable projects was her documentation of historic architecture in the American South. In 1933, she was commissioned by the Carnegie Corporation to photograph historic homes and buildings in Virginia, Maryland, and North Carolina. This work resulted in a series of photographs that are now housed in the Library of Congress. Throughout her career, Johnston was also an advocate for women in photography, and she worked to promote the work of other women photographers. She was a founding member of the Women's Professional Photographers' Association and the Photo-Secession, a group of photographers who sought to elevate photography as an art form.
