Lillian Blauvelt (1873–1947) was a popular opera singer in New York City and internationally in the first decade of the 20th century. Her voice was a lyric soprano with a very pure timbre and dramatic distinction. Her vocal range was from G to D. She was from Brooklyn, New York, and eventually toured every country in Europe.
She was a graduate of the National Conservatory of Music. Blauvelt sang in concerts in New York City and Brooklyn prior to becoming the soprano of the West Presbyterian Church,42nd Street between Fifth Avenue and Sixth Avenue, in 1893.
In January 1893 she sang the air (music) for Aida from Act I, and the duet for Aida and Amneris from Act II, with Mrs. Luckstone-Myers, a contralto. The Sunday concert was held at Music Hall.
In 1898 she sang under Sir Henry Wood at the Royal Albert Hall in London. Forty years later his list of the finest artists he had ever worked with included Ferruccio Busoni, Fritz Kreisler, Pablo Casals and Lillian Blauvelt.
She performed with the New York Symphony at Carnegie Hall. In the ninth season of Symphony Concerts for Young People, 1904, the program was devoted to works by Bizet, Gounod, Verdi, and Richard Wagner. Blauvelt and Edward P. Johnson were soloists with the orchestra conducted by Frank Damrosch.
