== Relocation to United States == He emigrated to the United States in 1894 where he eventually became a naturalized citizen. He was organist at The Church of St. Francis Xavier from 1894 until 1907. After he left in 1907 the position was filled by Italian organist Pietro Yon who would eventually become organist at St. Patrick's Cathedral.
== Juilliard School == He taught organ on the faculty of the Juilliard School from 1907 until 1945. Among his notable pupils were Ray Lev, Marcelle Martin, Carl McKinley, Georges-Émile Tanguay, and Powell Weaver.
