The Chicago Public Library's regional library for the North Side was named for Conrad Sulzer (1804-1873), who immigrated to Chicago from Switzerland and was one of the earliest known settlers of the Lake View community. Sulzer purchased 100 acres of land and became very active in the civic affairs of the community, holding several public offices. The Conrad Sulzer Regional Library, at 4455 North Lincoln Avenue, opened its doors to the public in September 1985. It replaced the Frederick H. Hild Branch Library at 4544 North Lincoln Avenue, which had been serving the community since 1931. Designed by the firm of Hammond, Beeby & Babka in the neo-classical style, Sulzer contains 65,000 square feet and includes an auditorium accommodating 200 people, an expanded browsing area and a neighborhood historical room housing the Ravenswood-Lake View Community Collection.
