The Art Institute of Chicago was founded as both a museum and school for the fine arts in 1879, a critical era in the history of Chicago as civic energies were devoted to rebuilding the metropolis that had been destroyed by the Great Fire of 1871. The Art Institute found its permanent home in 1893, when it moved into a building constructed on what is recognized today as the traditional homelands of the Council of Three Fires—the Ojibwe, Odawa, and Potawatomi peoples. Built jointly with the city of Chicago for the World’s Columbian Exposition at the intersection of Michigan Avenue and Adams Street, that building—its entry flanked by the two famous bronze lions—remains the “front door” of the museum even today.
In keeping with the academic origins of the institution, a research library was constructed in 1901; eight major expansions for gallery and administrative space have followed, with the latest being the Modern Wing, which opened in 2009. The permanent collection has grown from plaster casts to nearly 300,000 works of art in fields ranging from Chinese bronzes to contemporary design and from textiles to installation art.

Formerly a royal palace, the Louvre has embraced the history of France for eight centuries. Intended as a universal museum since its inception in 1793, its collections—among the finest in the world—span several thousands of years and a territory that extends from America to the confines of Asia. Divided among eight departments, these collections feature works admired throughout the globe, including the Mona Lisa, the Winged Victory of Samothrace, and the Venus de Milo. With nearly ten million visitors in 2012, the Louvre is the world’s most visited museum.

Together with its branch museum, the Renwick Gallery, SAAM holds works from the colonial period to the present, made in the United States.The collection includes works by such stylistically diverse luminaries as John Singleton Copley, Winslow Homer, and Georgia O’Keeffe, housed in one of the oldest public buildings constructed in early Washington.

There must be sufficient awareness of the artist's name for inclusion on Artcyclopedia.
The site collects "museum-quality art", however has no desire to be gatekeepers, i.e. arbiters of quality and merit. Normally taking cue from museum curators worldwide who are collecting and showing an artist's work signals that the artist has significance.
