Alfonso Iannelli was an Italian-American sculptor, artist, and industrial designer. Based in Chicago for most of his life, Iannelli was born in Andretta, Italy on February 17, 1888. He came to America in 1898. He studied to be a sculptor under Gutzon Borglum, later famous for Mount Rushmore. From 1910 to 1915, he designed posters for the vaudeville acts appearing at the Orpheum Theatre in Los Angeles. Frank Lloyd Wright's son John saw his work, and the two became friends. John introduced Iannelli's work to his father, Frank Lloyd Wright, who invited Iannelli to work with him on his Midway Gardens project in 1914. Iannelli created several of the Midway's Sprite sculptures for Wright. Wright, however, claimed credit for the pieces, leading to a bitter division and the ultimate demise of their partnership. He also collaborated with Chicago architect Ernest A. Grunsfeld III on several Art Déco-style plaques in 1929 to 1930 for the Adler Planetarium. These contributions include the zodiac signs of astrology and depictions of the planets in their mythological forms. About this time, Ianelli also designed an exterior fountain for the Riverside Studio in Tulsa, Oklahoma. Noted architect Bruce Goff completed the building in 1929 for a local music teacher named Patti Adams Shriner. The Riverside Studio was listed on the U.S. National Register of Historic Places in 2001. Afterward, Iannelli collaborated with noted Chicago areaPrairie School design architects Purcell and Elmslie, notably on the Woodbury County Courthouse, and with architect Barry Byrne for several church projects in the American Midwest, and one in Ireland. Iannelli also worked on numerous exhibitions at the 1933 Century of Progress, including the Radio Flyer and Havoline Thermometer buildings. He went on to open Iannelli Studios in Park Ridge, Illinois, in collaboration with his wife Margaret, a talented illustrator and artist in her own right. Iannelli Studios grew to become one of Chicago's most famous art studios at the time. They included more collaborators and expanded into commercial design, advertising, product design, and architectural interiors. Among Iannelli's most famous industrial designs are the Streamline Moderne-inspired C-20 "Coffeemaster" vacuum coffeemaker and T-9 electric toaster for Sunbeam Products, which the company introduced as its flagship modern appliances in honor of the 1939 New York World's Fair. Iannelli also designed many significant interiors for churches and movie theaters, two of which remain in operation today: the Pickwick Theater in Park Ridge and the Catlow Theater in Barrington, Illinois. He also designed the large-scale Rock of Gibraltar relief on the facade of the Prudential Building in Chicago. He died in Chicago on 23 March 1965.
