Miss Hart was a native of St. Louis, Missouri, and a graduate of Washington University, where she was a member of Gamma Phi Beta. She was involved in the St. Louis Artists’ Guild and the Independent Artists group. She also taught art, including adult classes at University City High School.

The artist had at least two solo shows in St. Louis, in 1954 and 1960. The ’54 show, a Guild effort, consisted of an astounding 79 paintings and drawings. Her work in portraiture drew praise, and she also excelled in still life and landscape while occasionally delving into abstraction. Critics noted a strong sense of humor in many of her pictures.

She worked as an executive secretary.
