[1] He was principal bass of the New York Philharmonic from 1892, after performing with the orchestra since 1880, and faculty at the National Conservatory, under the direction of Antonín Dvořák, and the Institute of Musical Art, which later became the Juilliard School.
Manoly originally came to Vienna as a boy soprano, who had an exceptional voice in choral music.
Upon arriving in Vienna at the age of fifteen, he found his voice changing and unable to audition at the Conservatory.
At the Vienna Conservatory, he studied double bass with Franz Simandl; harmony, counterpoint, and composition with Anton Bruckner; and conducting with Joseph Hellmesberger.
Graduating in 1876, he moved to the United States where he performed with the Theodore Thomas Orchestra, the Mendelssohn Quintette Club of Boston, and the Boston Symphony Orchestra.
