These included a Professor Cosmo in Trieste,[3] the Boston-based conductor and instrumentalist John C. Mullally[3] who had ties to the Boston Symphony Orchestra;[6] brass player and conductor John M. Flockton[3] who was a founding member of the Boston Symphony Orchestra's brass section as well as a leader of military bands in Massachusetts;[7] and New York music critic and piano teacher James Huneker.

[3] Hein also highlighted the influence of several of his relatives on his music development in this 1927 interview which included not only his mother but his aunt, Madame Riva, who sang with the Paris Opera, his maternal grandfather who had worked as a singer at the Teatro Lirico Giuseppe Verdi in Trieste, and his uncle, tenor Albert Pardo, who was a professional singer and church musician employed at St. Francis Xavier Church in Manhattan for 26 years.

[8] It was created as a starring vehicle for Marie Cahill, and the production later toured nationally under the new title Molly Moonshine after the Broadway run ended in January 1906.

His musical Marrying Mary (1906, Daly's Theatre) used lyrics by Benjamin Hapgood Burt and was based on Edwin Milton Royle's 1903 play My Husband's Wife.

[15] Hein's When Dreams Come True (1913, Lyric Theatre) was created for the dancer and actor Joseph Santley who in addition to starring in the production also choreographed the show.

[19] He had the biggest success of his career with the musical Flo-Flo (1917, Cort Theatre) which he created with the French librettist and playwright Fred de Gresac.

[26] Hein suffered from a bad chronic lung infection throughout much of his adulthood,[1] and was living during a period before modern antibiotics, such as penicillin, were available to the public.

[1] Ultimately, his health declined to the point that he was forced to retire at the relatively young age of 46; relocating to a sanatorium in Saranac Lake, New York.

Several prominent musicians and people connected to the American theatre were pallbearers at the funeral, including composers Jerome Kern, Irving Berlin, and John Philip Sousa; actor and 'Shepherd of the Lambs Club' Fritz Williams (1865–1930); Broadway producer and playwright R. H. Burnside; songwriter Raymond Hubbell; and music publisher George Maxwell who was the first president of the American Society of Composers, Authors and Publishers.
