    Mayor Gaynor attends the groundbreaking for Brooklyn's Central Library

    The groundbreaking for the Brooklyn Central Library took place on June 5, 1912, with Mayor William Jay Gaynor present, and a foundation contract was awarded that month. Surveyors found large amounts of peat moss on the site, and the building needed deep foundations because the Mount Prospect Reservoir was so close. The design was Raymond F. Almirall's Beaux-Arts scheme, of which only part would ever be built.

    The unfinished library becomes a campaign issue in the mayoral race

    The library saw no construction from 1918 to 1925, the years John Francis Hylan was mayor. His refusal to fund the building became a point of contention in the 1925 mayoral election, with his opponents claiming he had doubled the city budget while giving the library nothing. By then only one story of one wing was finished, under a temporary roof.

    A new chief librarian arrives to find a library one-third built and full of pigeons

    In October 1930 the library's trustees picked Milton James Ferguson, formerly chief librarian of California, to succeed Frank P. Hill as chief librarian. The building was only one-third complete, and thousands of pigeons had settled in the shell of the unfinished Flatbush wing. The New York Post described it as a "Roman ruin," while the Brooklyn Daily Eagle used the words "hideous old wreck."

    “Thousands of pigeons had made the shell of the unfinished Flatbush wing their home. The New York Post called it a "Roman ruin…”

    Flooded foundations of the stalled library become a play area, and a boy reportedly drowns

    Work stopped in 1931 once the foundations were done. After rain, the foundations of the Eastern Parkway wing flooded, and local children often played there with model boats; one boy reportedly drowned. By 1932 the library's directors were calling the site a monument to municipal procrastination, and it was also known as the Pigeon Palace.

    “…local children often played with model boats there; at one point, a boy reportedly drowned in the foundations.”

    Githens and Keally redesign the stalled library as an Art Deco building

    In May 1935 Borough President Raymond Ingersoll announced a redesign of the library by Alfred Morton Githens and Francis Keally, who moved most main public rooms to the ground story and the offices and backroom work to the upper floors. By February 1936 their preliminary designs were done: the original Beaux-Arts design was scrapped for an Art Deco one with a fan-shaped plan.

    “The original Beaux-Arts design was completely scrapped in favor of an Art Deco design, and the building was redesigned with a fan-shaped plan.”

    About 200,000 people sign a petition asking Washington to fund the library

    In February 1936 local leaders formed a committee to push for finishing the Central Library. From April to June 1936, roughly 200,000 people put their names on a petition to PWA secretary Harold L. Ickes, urging him to approve funding for the building. Ingersoll described the library at the time as Brooklyn's highest-priority needed improvement.

    “Between April and June 1936, about 200,000 people signed a petition asking PWA secretary Harold L. Ickes to approve money for the building.”

    The PWA authorizes $2.5 million to build the redesigned library

    General contractor Cauldwell-Wingate Company was awarded the $1.3 million contract for the redesigned library. The PWA authorized $2.5 million for the building that June, with only the first story to be fitted out at first. To save money, the existing frame was kept.

    The Ingersoll Memorial Library opens, and borrowing is capped within two weeks

    The Central Library first opened its doors to the public for previews on February 1, 1941, under the name Ingersoll Memorial Library, and limited service began two days later. No permanent library building in Brooklyn had opened for nearly two decades before it. Within two weeks patrons had borrowed so many books that the system limited how many each cardholder could take out, and the building was formally dedicated on March 29.

    A bronze screen over the entrance shows characters from American literature

    Above the triple doors of the library is a forty-foot bronze screen made of fifteen squares, each with a relief figure from American literature, among them Tom Sawyer, the Raven and Moby Dick, plus a portrait of Walt Whitman. Sculptor Thomas Hudson Jones designed it, and he also made two squirrel reliefs for the Children's Library gates. The flanking pylons carry gilded reliefs by C. Paul Jennewein showing the evolution of science and art.

    The second floor is finally finished, fourteen years after the library opened

    When the library opened the second floor was largely unfinished, and by late 1946 it still lacked flooring, lighting and radiators and had exposed wiring. In August 1952 the Board of Estimate appropriated $900,000 to fit it out. The New York Times noted that readers often had to stand in the main circulating room while the floor above was used for storage. The second story was completed in 1955.

    The Central Library is designated a New York City landmark

    The Landmarks Preservation Commission designated the Central Building of the Brooklyn Public Library a landmark on June 17, 1997, after a May 6 hearing at which three people spoke in favor, including a library representative. The designation report notes that the library, first proposed in 1888, took nearly six decades to build. It names the building among Brooklyn's best known and busiest public buildings.

    The Dweck Center auditorium opens beneath the rebuilt terrace

    The library planned a 200-seat auditorium under its rebuilt terrace. Raymond Almirall's original design had included an auditorium, but it was never built for lack of money. The new one opened in October 2007 and was named for Dr. S. Stevan Dweck, who gave $1.5 million. The Dweck Center in the basement has hosted fundraisers and parties and, as of 2011, over 100 events a month.

    “The auditorium, which was supposed to be completed in mid-2007, opened that October and was named for S. Stevan Dweck, a doctor who donated $1.5 million.”
