Friedrich Hassel, real name Friedrich Laube, (23 April 1815 in Spangenberg[1] or Kassel[2][3] – 29 September 1884) was a German child actor, stage actor, operatic tenor and opera director.
Hassel's stepfather, who was engaged at the Staatstheater Kassel, approved of it when he became interested in the stage at an early age.
At the age of nine he entered the stage for the first time as a "choirboy" and one year later he already sang the "first boy" in The Magic Flute.
There he also discovered his voice, took lessons with Ferdinand Pillwitz and got himself cast before long as "Telasco" in Gaspare Spontini's Cortez to stormy applause.
Besides his singing career he didn't neglect acting and enjoyed great popularity especially in the genre of youthful, humorous roles.
