The Brooklyn Museum is an art museum located in the New York City borough of Brooklyn. At 560,000 square feet (52,000 m2), the museum is New York Citys third largest in physical size and holds an art collection with roughly 1.5 million works. Located near the Prospect Heights, Crown Heights, Flatbush, and Park Slope neighborhoods of Brooklyn and founded in 1895, the Beaux-Arts building, designed by McKim, Mead and White, was planned to be the largest art museum in the world. The museum initially struggled to maintain its building and collection, only to be revitalized in the late 20th century, thanks to major renovations. Significant areas of the collection include antiquities, specifically their collection of Egyptian antiquities spanning over 3,000 years. African, Oceanic, and Japanese art make for notable antiquities collections as well. American art is heavily represented, starting at the Colonial period. Artists represented in the collection include Mark Rothko, Edward Hopper, Norman Rockwell, Winslow Homer, Edgar Degas, Georgia O'Keeffe, and Max Weber. The museum also has a "Memorial Sculpture Garden" which features salvaged architectural elements from throughout New York City. The roots of the Brooklyn Museum extend back to the 1823 founding by Augustus Graham of the Brooklyn Apprentices’ Library in Brooklyn Heights. The Library moved into the Brooklyn Lyceum building on Washington Street in 1841; the institutions merged two years later to form the Brooklyn Institute, which offered exhibitions of painting and sculpture and lectures on diverse subjects. In 1890, under its director Franklin Hooper, Institute leaders reorganized as the Brooklyn Institute of Arts and Sciences and began planning the Brooklyn Museum. The Museum remained a subdivision of the Brooklyn Institute of Arts and Sciences, along with the Brooklyn Academy of Music, the Brooklyn Botanic Garden, and the Brooklyn Childrens Museum until the 1970s when all became independent.
