Humberto Waldemar Asdrúbal Baeza Fernández, also known as Tito Fernández, El Temucano, was a Chilean singer-songwriter and folklorist. He recorded and released more than 40 albums from the 1970s to the present.
Fernández was born in Temuco but moved to Santiago as a teenager. In his 20s, he began singing in pubs and bars in the north of Chile, Peru, and Bolivia. He was imprisoned during the battle between the Bolivian army and Che Guevara's guerrillas.
Fernández returned to Chile in 1971. He moved to Santiago where he recorded his music and shared the stage several times with Victor Jara. He was also active with the Juventudes Comunistas de Chile. However, unlike other singers of the Nueva Canción Chilena, Fernández also had followers within the military and right-wing.
After the military coup in 1973, he was assigned to deliver Victor Jara's wedding ring to his widow. Fernández was himself detained by the military after the coup and imprisoned for a short time at the Escuela de Aviación, where he had studied in his youth. He was given the work of being a waiter serving military personnel at the school.
