New York Public Library, Muhlenberg Branch, ca. 1912. Completed in 1906, the Muhlenburg Branch is a Carnegie library designed by the same architects of the Main Branch of the NYPL, Carrère and Hastings. The simplified Beaux Arts style building is named for William Augustus Muhlenberg. He was the first rector of the nearby Church of the Holy Communion, and donated many books to the Free Circulating Library (a precursor to the NYPL).

📚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. 📚
