Hermon A. MacNeil (1866 – 1947), was an American sculptor who is known for designing the Standing Liberty quarter, struck by the Mint from 1916-1930, and sculpting Justice, the Guardian of Liberty on the east pediment on the United States Supreme Court Building. He was best known for his work with Native American subjects, and gained acclaim for his work as a portrait sculptor. He was taught sculpture in many art institutions, and gave Augusta Fells Savage private lessons when her acceptance to the Fontainebleau School of Fine Arts was retracted after it became clear she was Black.

MacNeil was born in Massachusetts and graduated from Massachusetts Normal Art School (now the Massachusetts College of Art and Design) in Boston, and then became an instructor in industrial art at Cornell University from 1886-89. He later studied under Henri Chapu and Alexandre Falguière in Paris and was granted a scholarship to study in Roma for four years. He went to Chicago to collaborate with Frederick MacMonnies1893 World's Columbian Exposition, and then came back to teach at the Art Institute of Chicago for a few years.

He married fellow sculptor Carol Brooks in 1895 and they went to Rome and lived there for 3 years until 1899 before moving to Paris. The couple came back to the United States around 1900 when their first son was born, and soon after they purchased a home in College Point, where he lived and worked until he passed away in 1947.
