58th Street Branch, July 8, 1928. Designed by Carrère and Hastings and opened May 10, 1907, the 58th Street Branch looks very different today. The original wide library building was demolished in the 1960s and was replaced in 1969 by a new branch in the lower floors of an office tower at the same location.

📚In 1901 after selling his corporation for $500 million, steel magnate and philanthropist Andrew Carnegie announced a $5.2 million donation to the City of New York for the construction of public library buildings. With this gift, 67 branch libraries were constructed in the five boroughs between 1903 and 1929. 📚

Arion Hall, ca. 1908. Founded in 1854 to promote "the perpetuation of love for some of the characteristic elements of German civilization," the Arion Society was a musical group that built this headquarters in 1886-1887. The grand pile was an Italian Renaissance style building with stone balconies, two sculptural groupings at the roofline, Guastavino-tiled arches inside that created huge vaulted spaces, a German beer hall, and a ballroom with seating for 500. While the society was successful through the end of the 19th century, performing at the White House and hosting international statesmen, they ran into trouble by the entry of the U.S into the Great War. When asked to sign a “pledge of loyalty to President Wilson," along with other German societies, the Arions refused. Their response was, “we regard the invitation to sign as a doubt of our loyalty and therefore an insult.” Soon after, a member refused to play the Star-Spangled Banner during a classical concert. (The conductor stated it was not a un-American sentiment, but that the song is "decidedly unclassical and did not fit in with the programme.") These actions proved the death knell for the society. They sold the clubhouse within weeks to the brewer George Ehret, and the interior furnishings were sold at public auction. The later history of the building is strange and varied. It served as the Anderson Galleries, home to art dealers, agents, and appraisers. Then it was empty between 1931 and 1946 before opening the Park Avenue Theater, a “unique and artistic movie house designed to meet the needs of a subscription clientele.” By 1957 the building had a bank, an auto salesroom, and a dance studio. Then it became the Chapel of Saints Faith, Hope, and Charity, an annex of St. Patricks's. Finally, in the late 1970s, the diocese sold the building, and the new owner razed the four-story building for a sleek new office building completed in 1981.
