Park Slope Branch, ca.1925. Completed in 1906 to the designs of Raymond F. Almirall, the current Park Slope Branch was originally named the Prospect Branch (it was renamed in 1975). Raymond F. Almirall designed four Brooklyn branches and was a member of the Brooklyn Carnegie Committee’s Architects’ Advisory Commission. Built in a Classic Revival style, the building is set back from the street and is symmetrical in floorplan. The interior of this branch is notable for being particularly ornate and largely still original. The entrance floor is a multi-colored mosaic and the walls of the reading rooms are clad in wooden wainscoting. Other interior features include arched stained glass windows and tiled and wood-framed fireplaces.

Ansonia Clock Company, undated. Anson Green Phelps founded the Ansonia Brass Company in 1844, and six years later the Ansonia Clock Company was founded in Connecticut as a subsidiary of the parent company. For the next eight decades, Ansonia was one of the major clock manufacturers in the United States. This clock factory, which occupied much of the block between Seventh and Eighth Avenues and 12th and 13th Streets, opened in 1879. The factory is lost to a terrible fire in 1880 and rebuilt in the same location the following year. The company condensed its production into Brooklyn in the mid-1880s. 1914 was a banner year for the firm which was then producing 440 different clock models. The war years were hard on the business and they never fully recovered, particularly with new competition in the novelty clock market. The Ansonia Clock Company sold this building in 1926 and sold the business to Soviet Russian interests in 1929. Today the building is a co-op called Ansonia Court.

Grocery store and frame buildings on Sixth Avenue, north of 16th Street, 1940. The corner store awning advertises the grocery as a “direct receiver of butter and eggs,” presumably fresh. Photographer P.L. Sperr describes nos. 567 and 569 as “very old frame dwellings.” Today, both structures remain, but the clapboards have been replaced with vinyl and brick veneer siding.

Park Slope Branch, Brooklyn Public Library 431 Sixth Avenue Raymond F. Almirall, 1905-06 This library was originally the Prospect Branch, housed beginning in 1900 in Prospect Park’s Litchfield Villa and consisting solely of books related to natural history. As Park Slope’s population grew, the demand for a larger, all-purpose library led to its relocation in 1901 to several storefronts on 9th Street between 5th and 6th Avenues. By 1904, the city purchased a large site and began planning for a new Carnegie-funded building. Its name was changed to Park Slope in 1975. The Classical Revival style, brick-clad building with limestone trim features an imposing, projecting portico entrance with Doric columns and a stone pediment. Like those found on the Pacific Branch, the torches in the keystones above the entrance and windows represent the light of learning. Its intact interior features stained glass, tiled fireplaces, wood paneling and marble mosaic floors. The Park Slope branch was designated in 1998.
