Nicholas Longworth II was a lawyer from a prominent Cincinnati, Ohio, family who served on the Ohio Supreme Court.

Joseph Longworth was an American lawyer, real-estate magnate, art collector, and philanthropist. A member of the wealthy Longworth family, he helped shape cultural life in Cincinnati for a generation. Longworth sold the parcel of land that would become Eden Park, including the land that would be used for the Cincinnati Art Museum. He also contributed to the construction of the museum and served as its first president. Longworth was the "prime mover" for the Art Academy of Cincinnati, arranging the movement of the school to Eden Park, planning its integration with the museum, and endowing it with $370,000. In 2013 the original Art Academy building was renamed the Longworth Wing of the Cincinnati Art Museum in his honor.
