From Wikipedia: American singer and composer, born in Brooklyn, New York. She became a vaudeville singer, singing at venues like The Abbey and Tony Pastor's.

In 1896, she composed and wrote the lyrics to "Sweet Rosie O'Grady", which became one of the most popular waltz standards of the time. The song was initially rejected when she tried to sell it to Tin Pan Alley publisher Joseph W. Stern & Co.; Stern's partner Edward Marks recounted that they changed their minds as soon as she left their office to market it elsewhere, and he chased her down the street to make an offer. The sheet music for the song sold over million copies. In 1899 it was recorded by Lil Hawthorne for Berliner Gramophone.

Nugent continued to compose songs for a number of years, but none approached the success of "Rosie O'Grady". Nugent performed her own songs, introducing many of them to audiences in this manner. Occasionally she collaborated with her husband, fellow-songwriter William Jerome.

Nugent retired from performing when she was 28 in order to raise a family; however, she continued to write music. In the 1940s and -50s, "Gay Nineties" revues came into vogue and Nugent began to perform again, on television.

She died June 3, 1958 in New York.
