Charles Follen McKim in the context of McKim, Mead, and White

McKim, Mead & White was an American architectural firm based in New York City. The firm came to define architectural practice, urbanism, and the ideals of the American Renaissance in fin de siècle New York.

The firm's founding partners, Charles Follen McKim (1847–1909), William Rutherford Mead (1846–1928), and Stanford White (1853–1906), were giants in the architecture of their time, and remain important as innovators and leaders in the development of modern architecture worldwide. They formed a school of classically trained, technologically skilled designers who practiced well into the mid-20th century. According to Robert A. M. Stern, only Frank Lloyd Wright was more important to the identity and character of modern American architecture.

The Low Memorial Library (nicknamed Low) is a building at the center of Columbia University's campus in Upper Manhattan, New York City, U.S. The building, located near 116th Street between Broadway and Amsterdam Avenue, was designed by Charles Follen McKim of the firm McKim, Mead & White. The building was constructed between 1895 and 1897 as the university's central library, although it has contained the university's central administrative offices since 1934. Columbia University president Seth Low funded the building with $1 million (equivalent to $38 million in 2024) and named the edifice in memory of his father, Abiel Abbot Low. Low's facade and interior are New York City designated landmarks, and the building is also designated as a National Historic Landmark.

Low is arranged in the shape of a Greek cross. Three sets of stairs on the library's south side lead to a colonnade with a frieze describing its founding. The steps contain Daniel Chester French's sculpture Alma Mater, a university symbol. The library is four stories tall, excluding a ground-level basement. The building's raised first floor has an entrance vestibule, as well as an ambulatory around an octagonal rotunda, which leads to offices on the outer walls. The rotunda contains a sky-blue plaster dome and four Vermont granite columns on each of its four sides. The library's stacks could store one-and-a-half million volumes; the east wing hosted the Avery Architectural Library and the north wing hosted Columbia's law library.

William Rutherford Mead (August 20, 1846 – June 19, 1928) was an American architect who was the "Center of the Office" of McKim, Mead, and White, a noted Gilded Age architectural firm. The firm's other founding partners were Charles Follen McKim (1847–1909) and Stanford White (1853–1906).
