Daniel Eggert was born in Bückeburg, Lower Saxony, where he participated in music and music theatre from a young age.
After graduating from high school he began his studies to become a secondary school teacher (subjects: music and german) in Hannover, before he later devoted himself to vocal studies, which he applied equally in the fields of song, oratorio and opera, accompanied by diverse ensemble work  with the music from the Renaissance to the modern times.
While studying under Ks. Prof. Astrid Schirmer and Prof. Jacques Schwarz in vocals and Prof. Jan-Philipp Schulze for Lieder, he participated in numerous master classes, including Deborah Polaski, Barbara Bonney and Daniel Ferro.
Daniel Eggert was the recipient of several scholarships, such as Fellow of Yehudi Menuhin's "Live Music Now" and the Richard Wagner Verband Hannover.
His first stage experiences included classic operas, e.g. as Dr. Bartolo in Mozart's Figaro and Claudius in Handel's Agrippina, as well as contemporary works, such as Bom in Heinz Holliger's Beckett setting "What where".
During his studies he also made his debut at the Festspielhaus Bayreuth in »Tannhäuser für Kinder« and at the Prinzregententheater München as Soljony in Peter Eötvös »Tri Sestri«. A year later he performed in »Tri Sestri« at the Staatsoper Unter den Linden Berlin and later in a premiere for the opening of the season at the Zurich Opera House.
Other commitments have taken him in the meantime to Paris, to the New Forum Hamburg, the Handel Festival Göttingen and the theaters Aachen, Braunschweig and Hildesheim.
Daniel is often a guest of the NDR Radio Philharmonic, where he was last seen as Marchese d'Obigny in "La Traviata" and as Conte di Ceprano in "Rigoletto" at the Classic Open Airs 2016 and 2017 of the NDR.
In the lieder repertoire he devotes himself not only to the 'classics'- Schubert, Schumann, Brahms and Strauss- but also works by Shostakovich, Aaron Copland, Ralph Vaughan Williams and most recently the world premiere of "Moments: Signatures", one of the song cycles of the young composer Stefan Johannes Hanke.
First hired as a founding member of the ensemble of the 'Junge Oper' Hannover, Daniel has been a solo ensemble member at the Staatsoper Hannover since 2012. He has made his debut there in more than 20 roles, last u.a. as Sparafucile, Eremit,  1st Nazarener / Salome, king / Aida and as Sarastro.
In the current season, he recently gave his debut as Brander in Berlioz "Damnation de Faust" in Hanover and will soon be there as Seneca in Monteverdi's "L'incoronazione di Poppea".
