From the period sources

Gaston Marie Dethier, a “brilliant Belgian organist” according to The New Encyclopedia of Music and Musicians (1924), was born in Liège in 1875. He trained at the Liège Conservatory and was a pupil of Guilmant. By 1894, Dethier had become organist at St. Francis Xavier’s in New York, and since 1907, he served as a professor at the Institute of Musical Art, alongside an active concertizing career. His brother, Edouard Dethier, a Belgian violinist, also taught at the Institute of Musical Art in New York and toured extensively in America as a concert-violinist, as noted by Grove’s Dictionary (1920). The brothers collaborated in 1915, giving “notable sonata-recitals” for violin and piano, as The New Encyclopedia of Music and Musicians (1924) records. Dethier’s influence extended to his students, with Weston Gales, a specialist in boy-choir training and later founder of the Detroit Symphony Orchestra, studying organ with Dethier at Yale, according to Grove’s Dictionary (1920).
