Hortensia Bussi, the widow of former Chilean President Salvador Allende, has died at the age of 94.The renowed left-wing activist passed away in her sleep. A professor of history and geography, Bussi – also known as Tencha – was often seen at the side of her husband, who was elected president of the South American country in 1970. But the socialist leader’s rule was ended by a violent military led coup d’etat three years later. Allende allegedly killed himself while under air and ground attack at the presidential palace, rather than surrender. Bussi went into exile in Mexico but returned in 1990 after civilian rule was restored and spend the last few years virtually confined to her Santiago home.
