Life and career
Born Louisa Melvin in Providence and later a resident of Boston, Melvin Delos Mars was one of the earliest African-American women to achieve recognition as a composer. She was one of the first black individuals to graduate from the New England Conservatory and first achieved notice in the 1880s singing alongside her sister, Carrie Melvin Lucas, who played cornet and violin. Her sister was the wife of vaudeville entertainer Sam Lucas, and their daughter and Louisa's niece, Maria Lucas, also became a popular trombonist, pianist, and conductor who eventually became the music director at the Howard Theatre in Washington, D.C.

Melvin Delos Mars was the first African-American woman to have an opera she composed produced: Leoni, the Gypsy Queen in Providence, Rhode Island in 1889. She went on to compose and star in four more full length operettas which were staged in either Boston, Massachusetts or Providence, Rhode Island between 1880–1896, including Fun At A Boarding School, and Love In Disguise; or, Things Are Not What They Seem. None of her works survive.
