Florine Stettheimer (August 29, 1871 - May 11, 1944) was an American artist. She has been described as "a Deco-influenced early Modernist whos never really gotten her due".
Florine was born in Rochester, New York to Joseph Stettheimer and Rosetta Walter. Her father, a banker, left the family before the children were grown. She was the fourth of five children: Walter, Stella, Carrie, Florine, and Ettie. After Walter and Stella married, the youngest three immured with their mother to form an epicurean way of life.She spent much of her early life traveling, studying art in Italy, Spain, France, Germany, and Switzerland. She studied for three years in the mid-1890s at the Art Students League of New York, but came into her own artistically upon her permanent return to New York after the start of World War I. In October 1916, the only one-person exhibition of her work during her lifetime took place at New York's Knoedler & Company. She exhibited 12 "high-keyed, decorative paintings", none of which were sold.
Cushioned by family resources, Stettheimer refrained from self-promotion and considered her painting "an entirely private pursuit". She intended to have her works destroyed after her death, a wish defied by her sister Ettie, her executor.
Stettheimer's privileged position pervades her work. As one critic has written, "money she regarded as a birthright, decidedly not something to be flaunted in the shape of a dozen yachts, but rather to be used as a palliative against the more unpleasant aspects of the world outside... In this frame of mind, she felt free to depict life as a series of boating parties, picnics, summertime naps, parades and strolls down Fifth Avenue."
She created the sets and costumes for the 1934 production of Four Saints in Three Acts, an opera by Virgil Thomson with a libretto by Gertrude Stein. Her designs, which used cellophane in innovative ways, proved to be the project for which she was best known during her lifetime.
She assisted her sister Carrie in the creation of the Stettheimer Dollhouse, now in the collection of the Museum of the City of New York. The house is a whimsical depiction of an upper-class residence, filled with works by Stettheimer's artist friends, including William Zorach, Alexander Archipenko, and Gaston Lachaise.
