In 1905, Good Will–Hinckley School founder George W. Hinckley received $15,000 from the Carnegie Foundation for construction of a library on the expanding campus. This Carnegie library was unique in that it was for a private school. Hinckley hired New York architect Albert Randolph Ross, who designed an impressive single-story, Classical Revival edifice with central rotunda, portico, and flanking wings, all adorned with such classical features as Tuscan columns in antis and pediments. In the 1970s a suspended ceiling was installed beneath the dome.
