[3] Del Puente began his studies at the Conservatory of San Pietro a Majella as a young boy, originally devoting himself to cello under Gaetano Ciandelli.

[4] Upon discovering a fine baritone voice, he studied singing under Alfonso Guercia and Domenico Scafati,[5] himself a student of Alessandro Busti and the castrato Girolamo Crescentini.

Del Puente made his baritone debut at Iași, Romania alongside tenor Italo Campanini, with whom he would share many triumphs.

Quickly he was engaged with and sang at the leading theaters in Europe, such as Apollo, Rome; La Scala, Milan; San Carlo, Naples; and others in Russia, Spain, Germany, and France.

Del Puente sang the role of Valentin in a cast that included Christina Nilsson, Italo Campanini, Sofia Scalchi, and Franco Novara.

At the Met, Del Puente created the roles of Barnaba and Alfio in the American premieres of La Gioconda and Cavalleria rusticana, respectively and being the leading baritone of the company, participated in several Met premieres of standard repertoire: Mignon, La traviata, Barbiere di Siviglia, Les Huguenots, and Carmen.

At Philadelphia, he created roles in the American premieres of Les pécheurs des perles, L'amico Fritz, and Manon Lescaut.

His grand ringing tones of such astounding beauty, richness and sonority could be modulated down to be just right for Alfonso in La favorita or any other Bel Canto role.

I have never heard him equalled Rossini's Barbiere, Meyerbeer's Nelusko in L'africana, the Count in Le nozze di Figaro, Amonasro in Aida, nor even approached in Il trovatore, or Carmen (Italian version).

He was buried at West Laurel Hill Cemetery in a grave that was unmarked until 1964, when local Philadelphia opera enthusiasts discovered it and erected a fitting monument.
